Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment one
The embodiment of the present invention one provides a kind of method determining captions point of addition, as shown in Figure 1, can comprise the following steps:
Step S101, determines that captions cover the set of pixel.
In this step, captions have specific color, have certain contrast grade with picture color, thus user can see captions clearly, and general captions color is white.Because the picture of video has continuity, captions can continue to show certain hour, and therefore captions have time shaft, all corresponding same captions of each frame picture play in this time shaft.Because captions color and character quantity are fixed, therefore the captions of captions in time shaft in each frame picture cover pixel quantity is fixed value.This fixed value can be called that captions cover the set of pixel, and namely captions captions in a frame picture cover the quantity of pixel.
Step S102, chooses captions and adds candidate region in picture.
In this step, the center visual effect marking area often of picture, in order to prevent captions from blocking visual effect marking area, the fringe region generally choosing picture adds candidate region as captions.Can divide captions at the top of picture and/or bottom and add candidate region, the height ratio that captions add candidate region and picture is preset value.As shown in Figure 2, divide two captions in this picture and add candidate region, lay respectively at top and the bottom of picture, two captions interpolation candidate region areas etc. are large, the ratio of picture central area and height is 0.618, then each captions add the height ratio of candidate region and picture is 0.191.
Step S103, captions are added candidate region and are divided at least two captions Adding Areas, by pixel iterative between each captions Adding Area by the set according to captions covering pixel.
In this step, captions Adding Area can hold the set that captions cover pixel.Cover the set of pixel according to captions, according to from left to right, captions are added candidate region and are divided at least two captions Adding Areas by order from top to bottom, by pixel iterative between each captions Adding Area.The division captions Adding Area schematic diagram that Fig. 3 provides for the embodiment of the present invention one, 1 for dividing the original position of captions Adding Area, 6 for dividing the end position of captions Adding Area, and the position of 6 is not fixed on the lower right corner, can divide each captions Adding Area according to the order of 1-2-3-4-5-6.The original position and the end position that divide captions Adding Area are not limited to the upper left corner and the lower right corner.Each division deducts the pixel no longer covered, and adds and newly cover pixel, thus realizes between each captions Adding Area by pixel iterative.
Step S104, calculates the pixel energy value of each captions Adding Area respectively.
In this step, because picture has continuity, in the captions Adding Area that can calculate each frame picture that captions cover, the set of the energy value of each pixel is as the energy value ∑ of captions Adding Area
re (I (x, y)).
Wherein,
rfor captions cover the set of pixel, E (I (x, y)) is the energy value of a pixel I (x, y) in the captions Adding Area of a frame picture;
Wherein,
for pixel I (x, y) difference in the horizontal direction,
for pixel I (x, y) difference in the vertical direction, x is the coordinate components of pixel I (x, y) horizontal direction, and y is the coordinate components of pixel I (x, y) vertical direction.
Step S105, according to pixel energy value, chooses captions Adding Area and adds captions.
In this step, pixel energy value is higher, vision significance is higher, otherwise pixel energy value is lower, and vision significance is lower, therefore, the minimum captions Adding Area of pixel energy value is generally the least significant region of visual effect in whole picture, adds captions, can prevent captions from blocking visual effect marking area in the captions Adding Area that pixel energy value is lower.Fig. 4 a is captions effect schematic diagram of the prior art, the captions effect schematic diagram that Fig. 4 b provides for the embodiment of the present invention one, can find out that captions have blocked part animated character in fig .4, and in Fig. 4 b, animated character shows complete.
By a kind of method determining captions point of addition that the embodiment of the present invention one provides, the continuity between the importance of video content and video pictures can have been considered, find the region that in video pictures, vision is relatively secondary, and add captions at this, effectively reduce and add captions blocking key content.
Embodiment two
The embodiment of the present invention two provides a kind of method that captions cover the set of pixel of determining, as shown in Figure 5, by the step S101 in the embodiment of the present invention one, can determine that the set of captions covering pixel is optimized for following steps:
Step S1011, rasterisation captions, generate the mask figure of captions, the mask figure of captions comprises: blank pixel and captions color filling pixel.
In this step, captions are made up of at least one character, captions " in " the mask figure of captions that generates, as shown in Figure 6, in figure 6, the pixel being labeled as 0 is blank pixel, and the pixel being labeled as 1 is captions color filling pixel.
Step S1012, the set of statistics blank pixel and captions color filling pixel covers the set of pixel as captions.
In this step, the set set of pixels of captions color filling pixel is combined into R
mask, the set of blank pixel and captions color filling pixel is R
sub, then
rcan be R
subor R
mask.
