Hello. I'm working with openCV and I'm a newbie in this field. I'm researching about Camshift. I want to extend this method by using multiple histograms. It means when tracking an object has many than one apperance (ex: rubik cube with six apperance), if we use only one histogram, Camshift will most likely fail.

I know calcHist function in openCV (http://docs.opencv.org/modules/imgpr....html#calchist) has a parameter is "accumulate", but I don't know how to use and when to use (apply for camshiftdemo.cpp in opencv samples folder). This function can help me solve this problem? Or I have to use difference solution?

I have an idea, that is: create an array histogram for object, for every appearance condition that strongly varies in color, we pre-compute and store all to this array. But when we compute new histogram? It means that the pre-condition to start compute new histogram is what?

Everybody please help me. Thank you so much!

P/S: Sorry about my language. I'm Vietnamese and I just know English. It's so difficult to find where is register place and post this topic. Hope everybody feel happy. Thanks.
