Matlab project for building motion estimator

My project is speeding up motion estimation for various video processing applications. Description- 1)Build a RavME Motion Estimator that uses motion from Compressed video as a kick start. Compare the below Measures of performance wrt to really good motion estimator(RGME) like EPIC Are the vectors from RavME the same as from full search BM? Are the vectors from RavME the same as ground truth or RGME? Is the prediction error from RavME the same or better than full search BM? Is the prediction error from RavME the same or better than RGME? 2)work on P - frame Select candidate motion vectors at a site .. remember to scale depending on how far in the past they point to For each candidate Measure DFD Measure Spatial smoothness Pick the best 3)B - frames == same thing Select candidate motion vectors at a site Flip the vectors around. So if you have one vector pointing back, then just negate it and make it also point forward Scale the vectors depending on the target frames For each candidate Measure DFD Measure Spatial smoothness Pick the best 4) then figure out for Iframe The code should be simple without using any matlab functions
