Dear

I have a snapshot of image captured by a camera. I need to calculate the area of specific color in that image. Any suggestions in this regard will be highly appreciated.

This operation is called color thresholding and is usually done in HSV space. To my knowledge there is no built-in function in MATLAB to do that, but I found this interesting page on File Exchange:

Color Threshold.

This was also the topic of a previous post in MATLAB Answers:

Color segmentation of skin markers: HSV or Lab? How to choose thresholds?.
