Color recognition using openCV
This is the one part of object recognition module exploring of openCV. Until now, i have successfully detected and recognized circle, rectangle and color which is presented here today. And next step is hand gesture recognition.
In color recognition, it can detect any color, but there’s still a little bug that, the detectation color should be preset before recognizing the objects in the destination image. I am not sure whether there’s any color filter in openCV like Actionscript3 which can just directly filter the necessary color objects.

I have interested in color recognition.

Actually, there are 3 methods to recognize the colour objects which are:
1) using histgram to match the destination image;
2) using cvSetImageCOI to get specific color channel;
3) using cvSplit & cvMerge to manipulate channel to get the target colours.
there i put on another post about color recognition using openCV here as well as some parts of codes, hope it will be useful: http://www.iandol.com/research/882.htm
Hi, interesting post. I have been thinking about this topic,so thanks for writing. I’ll likely be coming back to your blog. Keep up great writing
Thanks.
These days i am quite busy with some investigations, once get time, i will continue to post the latest recognition function applications by using openCV.
waiting to know the robust recognition functions..
Thank!
I ‘m very interested in color recognition
hope it helps.
