Abstract

In order to access an image sequence comprising individual search characteristics, search characteristics are stored correspondingly in an image sequence. A list comprising preferably plaintext search characteristics pertaining to an image sequence is thus prefixed, and stored behind the image sequence or inside the image sequence. Each search characteristic comprises a reference to an image inside the image sequence in addition to an information entry. Access is ensured via individual search characteristics.

Description

Verfahren zum Abspeichern von Suchmerkmalen einer BildsequenzMethod for storing search features of an image sequence
Die Erfindung betrifft ein Verfahren zum Abspeichern von Suchmerkmalen einer Bildsequenz und einen Zugriff auf die Bildsequenz anhand der Suchmerkmale.The invention relates to a method for storing search features of an image sequence and access to the image sequence on the basis of the search features.
Vielfältige audiovisuelle Information (Bildsequenzen) wird heute in digitalisierter Form an verschiedenen Orten gespeichert. Um diese audiovisuelle Information zu nutzen, ist es nötig, die interessierenden Daten zunächst einmal aufzufinden.A wide range of audiovisual information (image sequences) is now stored in digitized form at various locations. In order to use this audiovisual information, it is first necessary to find the data of interest.
Die MPEG-Standards zur Bildkompression sind dem Fachmann hinlänglich bekannt.The MPEG standards for image compression are well known to the person skilled in the art.
Zunächst wird auf die Bedeutung spezieller verwendeter Begriffe hingewiesen. Eine Bildsequenz kennzeichnet eine Reihe zusammenhängender Bilder. Eine Bildszene ist eine echteFirst, the meaning of specific terms used is pointed out. An image sequence identifies a series of related images. A picture scene is a real one
Teilmenge einer Bildsequenz und wird durch ein in MPEG- bzw. ITU-Standards definiertes Intrabild eingeleitet.Subset of an image sequence and is introduced by an intra image defined in MPEG or ITU standards.
Die Aufgabe der Erfindung besteht darin, ein Verfahren zum Abspeichern von Suchmerkmalen einer Bildsequenz/Bildszene anzugeben und einen Zugriff auf diese Bildsequenz/Bildszene über diese Suchmerkmale zu ermöglichen.The object of the invention is to provide a method for storing search features of an image sequence / image scene and to enable access to this image sequence / image scene via these search features.
Diese Aufgabe wird gemäß den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved in accordance with the features of patent claim 1.
Das Verfahren ermöglicht ein Abspeichern von Suchmerkmalen einer Bildsequenz und einen Zugriff auf die Bildsequenz anhand der Suchmerkmale, wobei die Suchmerkmale aus der Bildsequenz ermittelt werden. Die Suchmerkmale werden gemeinsam mit der Bildsequenz abgespeichert. Auf die Bildsequenz wird zugegriffen, falls in den Suchmerkmalen eine vorgegebene Information enthalten ist.The method enables search features of an image sequence to be stored and access to the image sequence based on the search features, the search features being determined from the image sequence. The search features are saved together with the image sequence. On the The image sequence is accessed if the search features contain predetermined information.
Eine Weiterbildung der Erfindung besteht darin, daß die Suchmerkmale Audiodaten und/oder Videodaten der Bildsequenz sind.A further development of the invention consists in that the search features are audio data and / or video data of the image sequence.
Eine andere Weiterbildung besteht darin, daß mittels der Suchmerkmale, die ihrerseits wiederum einen Verweis (Zeiger) enthalten, ein Zugriff auf ein Bild innerhalb der Bildsequenz möglich wird.Another development is that the search features, which in turn contain a reference (pointer), make it possible to access an image within the image sequence.
Der Zugriff kann dadurch erfolgen, daß der Verweis einen zeitlichen Offset innerhalb der Bildsequenz enthält und dadurch das Bild referenziert . Damit ist der Zugriff auf das Bild gewährleistet. Der Verweis adressiert also das Bild und damit einen Beginn innerhalb der Bildsequenz.The access can take place in that the reference contains a temporal offset within the image sequence and thereby references the image. This ensures access to the image. The reference thus addresses the picture and thus a beginning within the picture sequence.
In einer nächsten Weiterbildung ist es möglich, Suchmerkmale der Bildsequenz voranzustellen, einem Ende der Bildsequenz anzuhängen oder innerhalb der Bildsequenz abzuspeichern. Dies geschieht vorzugsweise mit Hilfe eines im MPEG- bzw. ITU- Standards definierten Intrabildes, das eine Bildszene einleitet und dem die Suchmerkmale vorangestellt werden können. Dabei können mehrere Bildszenen mit jeweils einem Intrabild innerhalb der Bildsequenz enthalten sein.In a next development, it is possible to prepend search features of the image sequence, to append it to an end of the image sequence or to save it within the image sequence. This is preferably done with the help of an intra image defined in the MPEG or ITU standard, which initiates an image scene and which can be preceded by the search features. Multiple image scenes, each with an intra image, can be contained within the image sequence.
Eine andere Weiterbildung besteht darin, jede einzelne Bildszene in einer Datenbank abzuspeichern und somit den Zugriff auf die Bildszene zu gewährleisten.Another further development consists in storing each individual image scene in a database and thus ensuring access to the image scene.
Eine zusätzliche Weiterbildung besteht darin, für einzelne nach dem MPEG- bzw. ITU-Standards definierte Objekte innerhalb der Bildsequenz jeweils eigene Suchmerkmale in der Bildsequenz abzuspeichern. Dadurch ist es möglich, auch auf solche Objekte bezogene, mit den Suchmerkmalen verknüpfte Einsprungstellen anzubieten. Auch ist es eine Weiterbildung, die Suchmerkmale durch einen vorgegebenen Startcode (Header) eindeutig zu identifizieren.An additional development consists in storing individual search features in the image sequence for individual objects defined according to the MPEG or ITU standards within the image sequence. This makes it possible to also offer entry points related to such objects and linked to the search features. It is also a further development to uniquely identify the search features by a predetermined start code (header).
Da die Suchmerkmale zusammen mit der Bildsequenz abgespeichert werden, kann eine umfangreiche Bilddatenbank aus einzelnen solcher Bildsequenzen zusammengestellt werden. Eine globale, vorzugsweise externe, Verweisliste hingegen, die Suchmerkmale und entsprechende Verweise auf die Bildsequenz enthält, erschwert einen modularen Aufbau derSince the search features are stored together with the image sequence, an extensive image database can be put together from individual such image sequences. A global, preferably external, reference list, on the other hand, which contains search features and corresponding references to the image sequence, complicates a modular structure of the
Bildsequenz (vor allem wenn diese aus mehreren Bildsequenzen besteht, die wiederum einzeln in andere Datenbanken exportiert werden sollen) .Image sequence (especially if it consists of several image sequences, which in turn are to be exported individually to other databases).
Weiterbildungen der Erfindung ergeben sich auch aus den abhängigen Ansprüchen.Further developments of the invention also result from the dependent claims.
Anhand der Figuren werden Ausführungsbeispiele der Erfindung näher dargestellt .Exemplary embodiments of the invention are illustrated in more detail with the aid of the figures.

In Schritt la der Fiσ.l werden Suchmerkmale aus der Bildsequenz bestimmt. Dazu werden Bilder gesucht, die einem gegebenen Musterbild ganz oder in Teilen entsprechen. Dies wird dadurch erreicht, daß das Musterbild zunächst auf vorgegebene Merkmale, insbesondere die vorherrschende Farbe oder typische auftretende Formen, analysiert wird. Diese Merkmale werden in einer Datenbank abgespeichert und mit einem Zeiger auf das zu referenzierende Bildmaterial, also das gefundene Musterbild innerhalb der Bildsequenz, referenziert . Die Suchmerkmale werden gemeinsam mit der Bildsequenz in einem Schritt lb abgespeichert. Schließlich wird der Zugriff auf die Bildsequenz anhand der Suchmerkmale in einem Schritt lc möglich, indem ein vorgebbares Merkmal mit den Suchmerkmalen verglichen und, falls eine Übereinstimmung gefunden wurde, zu der Bildsequenz innerhalb der Bildsequenz, die durch das Suchmerkmale referenziert wird, gesprungen wird.In step la of FIG. 1, search features are determined from the image sequence. For this purpose, images are searched which correspond to a given sample image in whole or in part. This is achieved by first analyzing the sample image for predetermined features, in particular the predominant color or typical shapes that occur. These characteristics are stored in a database and with a pointer to the image material to be referenced, i.e. the sample image found within the image sequence. The search features are stored together with the image sequence in a step 1b. Finally, access to the image sequence on the basis of the search features is made possible in a step 1c by comparing a predefinable feature with the search features and, if a match has been found, jumping to the image sequence within the image sequence that is referenced by the search feature.
Hierbei sei darauf hingewiesen, daß nicht ausschließlich die Videodaten referenziert werden können, sondern genauso Zeiger auf Audiodaten abgespeichert werden können.It should be pointed out here that not only the video data can be referenced, but also pointers to audio data can be stored.
In Fig.2 sind verschiedene Möglichkeiten gezeigt, die Suchmerkmale gemeinsam mit der Bildsequenz abzuspeichern.2 shows various possibilities for storing the search features together with the image sequence.
In Fig.2a ist eine Bildsequenz GOP (Group of Pictures, wie in MPEG-Standards definiert) , die einen Header H undIn Fig.2a is an image sequence GOP (Group of Pictures, as defined in MPEG standards), which has a header H and
Bildinformation BE enthält, dargestellt. Für alle Figuren 2a bis 2b gilt eine Zeitachse t, die vertikal von oben nach unten verläuft. Dadurch wird angedeutet, daß es sich um den zeitlichen Verlauf einer Bildfolge handelt, die als Bildsequenz abgespeichert ist.Contains image information BE. A time axis t which runs vertically from top to bottom applies to all of FIGS. 2a to 2b. This indicates that it is the temporal course of an image sequence that is stored as an image sequence.
In Fig.2a sind Suchmerkmale M der Bildsequenz GOP vorangestellt. Die Suchmerkmale M werden vorzugsweise in leicht lesbarer Form als eine Liste im Klartext (ASCII-Code) abgespeichert. Lange Listen mit Suchmerkmalen können zusätzlich komprimiert abgespeichert werden. Mit jedem einzelnen Suchmerkmal verbunden ist ein Zeiger PTR auf ein Bild innerhalb der Bildsequenz, wobei dieses Bild den Beginn einer Bildfolge, die mit dem Suchmerkmal verknüpft ist, innerhalb der Bildsequenz angibt. In den Figuren 2a bis 2d sind solche Verweise (Zeiger) als Pfeile PTR dargestellt.2a, search features M precede the image sequence GOP. The search features M are preferably stored in an easily readable form as a list in plain text (ASCII code). Long lists with search features can also be saved in compressed form. A pointer PTR to an image within the image sequence is connected to each individual search feature, this image indicating the start of an image sequence which is linked to the search feature within the image sequence. Such references (pointers) are shown as arrows PTR in FIGS. 2a to 2d.
In Fig.2b sind die Suchmerkmale M der Bildsequenz GOP nachgestellt. Ansonsten gilt das Gleiche wie bei Fig.2a.The search features M of the image sequence GOP are reproduced in FIG. 2b. Otherwise the same applies as in Fig.2a.
Die Suchmerkmale M können, wie in Fig.2c dargestellt, innerhalb einer Bildsequenz GOP abgespeichert sein. Entsprechend müssen mit den Suchmerkmalen M verknüpfte Verweise PTR auf Bildinformation vor (in Fig.2c oberhalb der Suchmerkmale M) oder auf Bildinformation zeitlich nach den Suchmerkmalen M (in Fig.2c unterhalb der Suchmerkmale M) verweisen.The search features M can, as shown in FIG. 2c, be stored within an image sequence GOP. Correspondingly, references PTR linked to the search features M must refer to image information before (in FIG. 2c above the search features M) or to image information temporally after the search features M (in FIG. 2c below the search features M).
Schließlich wird in Fig.2d die nach dem MPEG- bzw. ITU-Finally, in Fig.2d the according to the MPEG or ITU
Standards mögliche Codierung einzelner Objekte (Audioobjekte und/oder Videoobjekte) dargestellt. Dazu werden zu jedem Objekt 01 und 02 eigene Suchmerkmalssätze M31 und M32 ergänzt. Es kann eine audiovisuelle Szene mehrere Suchmerkmalssätze Ml, M2 , M31 und M32, enthalten.Standards possible coding of individual objects (audio objects and / or video objects) are shown. For this purpose, separate search feature sets M31 and M32 are added to each object 01 and 02. An audiovisual scene can contain several search feature sets Ml, M2, M31 and M32.
In Fig.2d beziehen sich die Suchmerkmalssätze Ml und M2 auf Bilddaten BD allgemein, während die Suchmerkmalssätze M31 und M32 jeweils Suchmerkmale enthalten, deren Einträge (Verweise) jeweils innerhalb der nach Objekten 01 und 02 getrennten Bildfolgen auf entsprechende zu referenzierende Stellen verweisen.In FIG. 2D, the search feature sets Ml and M2 relate to image data BD in general, while the search feature sets M31 and M32 each contain search features, the entries (references) of which, within the image sequences separated by objects 01 and 02, refer to corresponding locations to be referenced.
Eine Organisation einer Liste von Suchmerkmalen und deren Beziehung zu den Bilddaten BD ist in Fig.3 dargestellt. Es gilt wieder der vertikale Verlauf einer Zeitachse t von oben nach unten. Die Suchmerkmale M sind in Form einer Liste der Bildsequenz GOP, die den Header H und die Bilddaten BD enthält, vorangestellt. Die Liste enthält mehrere Suchmerkmale SMl und SM2. Jedes Suchmerkmal umfaßt jeweils eine beschreibende Komponente INF01 und INF02 und jeweils einen Verweis (Zeiger, engl . : pointer) PTR1 und PTR2 auf ein Bild innerhalb der Bilddaten BD.An organization of a list of search features and their relationship to the image data BD is shown in FIG. 3. The vertical course of a time axis t from top to bottom again applies. The search features M are prefixed in the form of a list of the image sequence GOP, which contains the header H and the image data BD. The list contains several search features SM1 and SM2. Each search characteristic comprises a descriptive component INF01 and INF02 and each a reference (pointer) PTR1 and PTR2 to an image within the image data BD.
Wie oben erwähnt, kann für eine nach dem MPEG-Standard komprimierte Bildsequenz die Liste logisch unterteilt sein, so daß sich bestimmte Suchmerkmale SMj_ auf vorgebbare Objekte innerhalb der nach dem MPEG-Standard komprimierten Bildsequenz ergeben. Vorzugsweise ist für die Unterscheidung zweier Objekte jedes zweite Suchmerkmal SM2J_ einem ersten Objekt und das andere Suchmerkmal SM(2i+ι) einem zweitenAs mentioned above, the list can be logically subdivided for an image sequence compressed according to the MPEG standard, so that certain search features SMj_ result for predefinable objects within the image sequence compressed according to the MPEG standard. For the differentiation between two objects, each second search characteristic SM2J_ is preferably a first object and the other search characteristic SM ( 2i + ι ) is a second
Objekt zugeordnet (i=0 , 1, 2 , 3 , ... ) . Entsprechend können für mehrere Objekte innerhalb der gleichen Bildsequenz unterschiedliche Suchmerkmalssätze angelegt werden. Object assigned (i = 0, 1, 2, 3, ...). Accordingly, different search feature sets can be created for several objects within the same screen sequence.
