Identifying living skin tissue in a video sequence using color and spatial similarities
According to an aspect, there is provided an apparatus for identifying living skin tissue in a video sequence, the apparatus comprising a processing unit configured to receive a video sequence, the video sequence comprising a plurality of image frames; divide each of the image frames into a plurality of frame segments, wherein each frame segment is a group of neighboring pixels in the image frame; form a plurality of video sub-sequences, each video sub-sequence comprising a frame segment from two or more of the plurality of image frames; analyze the plurality of video sub-sequences to determine a pulse signal for each video sub-sequence; determine a similarity matrix based on pairwise similarities for each determined pulse signal with each of the other determined pulse signals; and identify areas of living skin tissue in the video sequence from the similarity matrix.
