( body )

Hi, i am new to image processing and openCV C/C++. I am wondering that is it possible to extract skin tone from the first image (face

Answer 1

This is a hard problem to solve, especially given the variation of colours depending on lighting and reflection. I have worked previously on finding skin in images, and generally the Cr (chroma red) component of the YCbCr colour space stands out prominently on skin. You might be able to exploit this information to find skin regions.

Here are a couple of papers that attempt to use colour for locating human skin: 1. Interaction between hands and wearable cameras 2. Markerless inspection of augmented reality objects
