Abstract:
1. A method comprising: causing down-sampling of image data received to generate down-sampled image blocks for a plurality of image frames; causing extraction of a plurality of features from the down-sampled image blocks; determining a moving status of the down-sampled image blocks based on changes in values of respective features in consecutive frames; determining, using a processor, a direction of motion of an object in the image data based on movement of a first border and a second border of a projection histogram determined based on the moving status of respective down-sampled image blocks, wherein determining the direction of motion comprises determining a non-moving block based on the moving status of connected neighbor blocks; and verifying a detection of movement of the object based on color histogram analysis, wherein the verification of the detection of movement comprises dividing one or more frames into a predetermined number of regions and sub-regions, determining a three dimensional histogram corresponding to each of the predetermined number of sub-regions, and down sampling one or more channels corresponding to the three dimensional histogram.
