As a result, the ASPVC-Global algorithm using five random starts and up to four pattern modes may requires extra 0.58 of a mode ME&MC operations compared to the H.264 which would not be a problem in real time processing.
In order to determine the computational complexity of the proposed ASPVC-Global algorithm, let us compare it with the H.264 standard.
When the proposed ASPVC-Global scheme is embedded into the H.264 as an extra mode, additional one-fourth motion search is required per MB as the pattern size is a quarter of a macroblock.
Thus, the proposed ASPVC-Global with 100 random starts and 9.73 (according to Figure 5) inner-loop iterations until τ = 100% requires no more than 5.4 times operations compared to the full motion search by a mode where search length is 15.
In the proposed technique, near-global-optimal arbitrarily shaped PVC (ASPVC-Global) uses a pattern codebook that comprises eight patterns with 64 pixels as '1'.
In this paper, we highlighted two transmission modes at the global scale through a spatial-temporal analysis: the poultry transmission mode and bird migration mode.
This allows moves between separate modes, ensuring a global exploration of the model state space.
The device operates in two distinct shutter modes: rolling and global.
The modes with the lower frequencies represent preferential global motions.
Figure 10 shows some decoded frames for visual viewing comparison by the H.264, the IBS [12], the ASPVC-Local [16], PVC [15], and the proposed techniques.
