1. Week 4 Report UCF Computer Vision REU 2012 Paul Finkel 6/11/12

2. Accomplishments Sampled optical flow matrices, Eulerian – 4x4 grid – 16x16 grid Canonical correlation between rows of videos – Unusually high values, even for non-dense crowds Nothing lower than.8 – Debugging code

3. Accomplishments (cont’d) Cuboid extraction of optical flow – Very generalizable Histogram of optical flow (HOF) of cuboids Found a few videos for our dataset

4. Things to work on Get correct values for correlation – Fix/change method Test correlation on histogram of optical flow – Compare with canonical correlation values Extract useful frames of videos for our dataset
