A Motion Detection Algorithm Using Local Phase Information

Figure 6

Evaluating the motion detection algorithm at time (see also Supplementary Video S1). (a) A still from a -pixel video at time . (b) for all blocks, each of size . The blocks are concatenated to create a large “phase image” with their relative neighbors kept. (c) shown in the space. (d) shown in the space. (e) Phase Motion Indicator (PMI) for all blocks at . Each pixel is color coded for . (f) for all blocks at . Each pixel is color coded for this maximum value of block .
