Thread parallel processing scheme
Figure 6.17 illustrates the frame pipelining technique for the thread parallel pro-
cessing shown in Fig. 6.16 . The horizontal axis is the time, and the time unit refers
to the processing time of each frame. Each output of the thread is given to another
thread that is processed one time unit later. Parallel execution of the threads is
achieved with this frame pipelining technique.
In the S-T MRF algorithm, the motion vector extraction is based on the sum of
the absolute difference between the sequential frames. The SAD algorithm is very
useful for evaluating the similarity between two frames, as depicted in Fig. 6.18 .
