A robust skin detector is the primary need of many fields of computer vision, including face detection, gesture recognition, and pornography filtering. Less than 10 years ago, the first paper on automatic pornography filtering was published. Since then, different researchers claim different color spaces to be the best choice for skin detection in pornography filtering. Unfortunately, no com...

Enhancing the performance of human face detection, tracking and recognition has been done by skin detection considering it as the fundamental step for the several decades. Of the evolved skin detection techniques, skin cluster classifier based on the human skin tone color are considered along with the concept of combination of two color spaces. This paper presents a novel method of combining mo...

Central cyanosis refers to a bluish discoloration of the skin, lips, tongue, nails, and mucous membranes, and is due to poor arterial oxygenation. Although skin color is one of its characteristic properties, it has long been realized that by the time skin color signs become visible, oxygen saturation is dangerously low. Here we investigate the visibility of cyanosis in light of recent discoveri...

Skin color detection is the process that classifies unknown colors into skin or non-skin classes. Skin color detection is preliminary step for facial or gesture analysis and can reduce search space for next higher level processing. In this paper, we show that proposed PCAbased color representation can give better performance than other frequently used color spaces such as XYZ and Luv. For skin ...

This research features a new method for skin color segmentation using a 2D plane in the RGB color space. The RGB color values of the input color image do not need to be converted into HSI or YIQ color coordinates that have popularly been used for color segmentation. We have observed an important fact that skin colors in the RGB color space are approximately distributed in a linear fashion. Base...

Detecting skin color from image sequences has played an important role in many computer vision applications, such as face detection and tracking. Even though there are a number of approaches for skin color detection, most of the existing algorithms produce false positives when non-skin pixels have similar color to skin color. To overcome this problem, this paper proposes a method that combines ...

This paper proposes skin color registration using the recognition of waving hands. In order to recognize hand gestures from images, skin colors are useful information. The proposed method can register skin colors simply and quickly because it uses just a few waves of the hand. The method consists of 2 steps. First, the regions of the waving hands are extracted from low-resolution images without...
