Skipping frames to improve cpu usage / power consumption

Frame Skipping when no movement improves cpu usage for guarddog

Frame Skipping when no movement improves cpu usage for guarddog

I Just added a frame processing skipper for when there are no changes on the frames (after a very quick check implemented here ) and therefore computation of faces , corners , RANSAC tracking and depth mapping has no meaning ( because the image remains almost 99% the same )
I will have to add some cooldowns ( i.e. 1 mandatory recalculation after 2000 milliseconds of skipping )

In the graph you can visually see when the skipping occurs and when normal processing takes place.. :P

This Behaviour is switched with VisCortx_SetSetting(USE_MOVEMENT_FLOW_FOR_CALCULATION_SKIPPING,1 or 0 :P )
