Embodiment 1
[0029] In the embodiment of the method for sorting the moving objects used for video surveillance provided by the present invention, the color standard obtained in step 1 and step 2 and the color vector of the color block are the process of characterizing the color, before obtaining the color vector It also includes: converting the data of the color standard or the color block from the RGB space to the HSV space.
[0030] The included color components are obtained by dividing colors, and the number of color components can be 9, which are: black, white, red, orange, yellow, green, cyan, blue and purple.
[0031] Such as figure 2 Shown is the flow chart of the method for counting the number of color blocks in each similarity coefficient level provided by the embodiment of the present invention, by figure 2 It can be seen that step 4 includes:
[0032] Step 401, set the total interval range of the similarity coefficient as [0.5, 1), divide the total interval range from small ...

The invention is suitable for the field of intelligent video monitoring, and provides a method for sequencing movement objects for video detection according to colors. The method comprises the following steps of 1, inputting the color standard for color sequencing, and generating a color vector containing a plurality of color components according to the data information of the color standard; 2, dividing the target picture into color blocks of n*n small areas, and calculating the color vector of each color block; 3, adopting a cosine correlation algorithm to respectively calculate the similarity coefficient of each color block and the color vector of the color standard; 4, classifying the similarity coefficient into different classes, and respectively calculating the number of color blocks in each similarity coefficient class; 5, sequencing the target pictures according to the number of color blocks of each target picture in each similarity coefficient class. The method has the advantage that the targets with certain color characteristics are searched and sequenced according to the similarity degree, so a policeman is helped to quickly find the suspected target, and the inquiry time is shortened.
Description
technical field [0001] The invention belongs to the field of intelligent video monitoring, in particular to a method for sorting moving objects by color for video investigation. Background technique [0002] With the development of science and technology, intelligent video surveillance system is widely used in public security criminal investigation business. It has become an indispensable part of criminal investigation technology to record pedestrian and vehicle behavior through video recording, and to find and track suspected targets from video. The essence of video reconnaissance is to find clues through surveillance video, so as to find suspicious targets. [0003] However, a large amount of surveillance video brings inconvenience to the criminal investigators to find the target, and consumes a lot of manpower and material resources. The technical solutions of invention patent applications titled "A Video Detection Technology for Acquiring Vehicle Features Based on Video...
