So, here I am enduring the cold Canadian winter chill for the sake of better slow motion video… First off, the camera is tripod mounted. The first 2 clips use a simple texture in the background (snow) The following 3 clips then use a more complex textured background (buildings, chainlink fence & a moving car). The experiment is to find what type of visual anomalies the motion compensation algorithm will add when recording biometric motion on various backgrounds. The conclusion? The ability of the algorithm to properly predict the biometric motion vector is compromised by the slow frame rate of the original capture (60 fps) regardless of the background’s texture density. However, It would seem that the algorithm is well suited for processing motion of slower movements on either type of background. In other experiments I have done, I’ve found that for a fluid biometric capture, your frame rate needs to be a minimum of 6 times higher (180 FPS). This is far beyond the capability of any NTSC or PAL camera system. In order to reach frames rates above 60 FPS your will need to use a more specialized type of camera system. I use a Lumenera LU175 Lumenera.com With this camera I can reach frame rates up to 873 FPS (at a much reduced resolution of 120×160 B/W). At a resolution of 320×240 I can reach rates of about 330 FPS which is suitable for biometric capture and analysis without using any motion compensation at all. The further use of motion compensation on video recorded at …

I dony like, i look so frame x frame video, isnt “smooth”…

It’s difficult to stretch out 30 frames to make it look like 300 frames. Not bad though. You should definitely look into the EXF1 if you enjoy HS stuff.

Good stuff, thanks for posting the information on it as well.

Wow lance, wow. Ha ha, jk. Too bad u didnt kick that snow as soon as that car went like behind it (hard to explain) so that it looked like the car hit it and it burst into a milion pieces. *****
