1. Face Detection in Color Images

2. Method Used
Face detection using skin color based segmentation

3. Data Set
A Data set of more than 100 singular face images with faces directly facing the camera to get a better skin color estimation.
Source :- Google and AltaVista search engines

4. Steps Followed
Use of HSV color space for color segmentation instead of RGB.
Training of the algorithm using the given dataset in HSV color space.
Using Images with multiple face images to generate the final results.

5. Results obtained
For Skin Color classification the algorithm gave the following results:
17/255 <= H <= 240/255

10. Future Work
Getting Better approximation of skin color using factors like saturation and Value in HSV and also using other models such as YCbCr for further refinement.
Extraction of actual faces from the segmented images using symmetric properties of face and elliptical objects
