Skin Color Detection

Question

I am using the following algorithm to detect skin color, but its not working real well in different lighting conditions. Can anybody offer any advice how to improve it or su

Answer 1

I've used chrominance components to quickly get skin-toned regions of an image.

It's not perfect, but it's alright if all you want is a quick and dirty approach.

The paper is called "Face segmentation using skin-color map in videophone applications" by Douglas Chai. It's a fairly old approach (1999). Unfortunately, the paper itself is behind a pay-wall, but the approach is fairly simple:

• Detect areas with potential skin tones by using a range for Cb and Cr
• Morphological operations to clean up image
• Using standard deviation, further separation of background (low) and foreground (high)
• Some more morphological operations to further clean up the image
• Contour reconstruction (smooth curves) to produce the result
