VIDEO STREAM ANALYSIS METHOD Russian patent published in 2018 - IPC G06T7/00 

FIELD: image processing means.

SUBSTANCE: invention relates to the processing of bitmap images. In the method, the first frame of the video stream is obtained, for each pixel of which the value of the following components is determined: luminance components Y, components of the color difference U and components of the color difference V; based on the obtained parameters YUV form pixel-by-pixel frame prediction; get the next frame of the video stream and carry out the analysis cycle, namely, determine the pixels related to the object, and form a binary mask of the detected object; for the mentioned pixels related to the object, determine at least one color similarity parameter and texture similarity parameter; compare the mentioned parameters of color similarity and texture similarity with their threshold values and classify each pixel as “shadow/non-shadow”, then refine the pixel-by-pixel prediction of the next frame and repeat the cycle.

EFFECT: technical result is to improve the accuracy of determining moving objects.
