Re: Tensorflow Updates?

Hi, kwagyeman
I saw CNN won't support multiple object detection in previous post, How about Tensionflow? In my project i can teach any of simple 10 objects initially and find position of each object in single frame at-least 10 FPS.

Re: Global Shutter

really I was waiting this release for my colour object tracking project, which I mentioned beginning. previous post was mentioned planning to use bayer sensor, any way if it won't support colour,I will get one colour sensor. In my place MT9V032 colour sensor available, I will start experiment with it.
