Abstract
The invention discloses a method for eliminating a false transition report caused by flashing, which mainly comprises the steps as follows: each frame in a video sequence is abstracted to generate a histogram of each frame; value differences between adjacent frames are computed according to the histogram of each frame; threshold values are computed according to the value differences between all the adjacent frames; the sizes of the value differences between the adjacent frames and the threshold values are compared on by one, and all current value differences larger than the threshold values are selected; according to the current value differences, a value difference between video frames corresponding to the current value differences and the histograms of two previous frames, and a value difference between one previous frame of a video frame corresponding to the current value differences and the histograms of five posterior frames are computed; and flashing points and transition points are judged via comparing the obtained histogram value differences and the threshold values. According to the invention, via the analysis of the value differences of adjacent frames in the video sequence and the comparison between the histogram value differences and the threshold values, the accuracy of transition point judgment and flashing points is improved, and false transition report caused by the flashing is eliminated.
Description
Technical field
The present invention relates to technical field of video processing, relate in particular to a kind of method that flash of light causes the transition wrong report of eliminating.
Background technology
Each paragraph (least unit that constitutes telefilm is a camera lens, one by one the shot sequence that is joined together to form of camera lens) all has certain single, complete relatively meaning, as shows a course of action, shows a kind of dependency relation, shows a kind of implication or the like.It is complete narration level in the telefilm, and just as the curtain in the drama, fictitious chapters and sections are the same, and paragraph links together one by one, has just formed complete telefilm.Therefore, paragraph is the most basic version of telefilm, and telefilm layer of structure in terms of content shows through paragraph.And transition between paragraph and paragraph, scene and the scene or conversion just are called transition.
Briefly, transition is exactly the camera lens switching in the video file, such as, video camera has been taken the auditorium earlier, switches to the rostrum then.
When daily TV programme are edited, usually earlier, find the point, transition in the video segment to the video analysis of cutting to automatically, bring convenience to editing.
Realize in the process of the present invention that the inventor inventor finds to exist in the prior art following technical problem:
Generally, the transition analysis all is a difference value of at first calculating consecutive frame in the video automatically, then according to the Changing Pattern of this difference value, finds than the big-difference place, and then is judged as point, transition.
If the flash of light camera lens is arranged in the video, so flash of light place will occur consecutive frame than big-difference, this will cause the wrong report that automatic transition is analyzed.
Summary of the invention
To defective of the prior art, the invention solves the problem that flash of light causes transition analysis wrong report.
In order to solve above technical problem, the invention provides a kind of method that flash of light causes the transition wrong report of eliminating, specifically comprise:
Extract each frame of video sequence, generate the histogram of each frame;
Difference value according to the histogram calculation consecutive frame of said each frame;
Difference value according to all consecutive frames calculates threshold value;
The size of the difference value of more said consecutive frame and said threshold value filters out all current difference value greater than said threshold value one by one;
Calculate the former frame of the corresponding frame of video of histogram difference and the said current difference value of the corresponding frame of video of said current difference value and front cross frame and the back histogram difference of five frames according to said current difference value;
Histogram difference that obtains and said threshold value are compared, if all surpass said threshold value, the corresponding frame of video of then current difference value is a point, transition, and if not, the corresponding frame of video of then current difference value is a shining point.
Wherein, comprise before each frame of said extraction video sequence: receive said video sequence.
Wherein, said histogram is stored in the one-dimension array.
Wherein, the difference value of said histogram calculation consecutive frame according to said each frame is specially:
According to the histogram calculation present frame of said each frame and the difference value of former frame, said difference value is stored in the two-dimensional array, and the sequence number of said two-dimensional array order in said video sequence is slided.
Wherein, said difference value according to all consecutive frames calculates threshold value and specifically comprises:
Difference value according to said consecutive frame calculates mean value;
Draw the difference value of the amplitude adjacent according to the maximum in said mean value and the said difference value greater than said mean value with said maximum;
Remove the difference value of the said maximum amplitude adjacent, calculate the mean value X and the mean square deviation Y of remaining difference value greater than said mean value with said maximum;
Threshold value is X+Y*Y.
Compared with prior art; The embodiment of the invention has the following advantages: through to the analysis of the difference value of consecutive frame in the video sequence and the comparison of histogram difference and threshold value; Increase the accuracy of judging point, transition and shining point, eliminate the transition wrong report that flash of light causes.
