Non-parametric histogram based skin modeling for skin detection

Digital Image Processing is a rapidly evolving field with increasing applications in science and engineering. Image Processing has the capability of developing the ultimate device that can perform visual functions of all living beings. An application of Image processing is skin detection. Skin detection is the process of finding skin colored pixels and regions in an image. Skin color arises due to melanin and hemoglobin, but there are many other objects in the world which are easily confused with skin, certain types of wood, copper, sand as well as clothes often have skin like colors. Therefore there is a need to properly formulate the skin detector, overcoming all the difficulties that arise in detecting skin in an image. This paper presents a technique for skin detection.
