This proved a but tricky, especially the Java part where you need to create your own buffer for the image, but […]

iPhone camera frame grabbing and a real-time MeanShift tracker

Published by under graphics,programming,video,work

Hi Just wanted to report on a breakthrough in my iPhone-CV digging. I found a true realtime frame grabber for the iPhone preview frame (15fps of ~400x300 video), and successfully integrated this video feed with a pure C++ implementation of the MeanShift tracking algorithm. The whole setup runs at realtime, under a few constraints of […]
