This Skin detection is process of extracting potential skin color regions from an image or video. Skin color detection restricts the work-space as it showcases human face, limbs and other exposed body features out of the whole image. Thus it can be used as a processing step in variety of applications like face detection and face recognition. Extraction of skin color pixels also help to identify pornographic image from the database of images and efficiently used for forensic purpose. It is been observed that there is positive correlation between images having large skin regions and the images which are pornographic in nature. We have implemented this approach using filtering of images in RGB and YCbCr color spaces using specific threshold values.
