Spatial Hand Segmentation Using Skin Colour and Background Subtraction
Despite advances in hand detection and hand tracking, robust hand segmentation remains a challenging task in many gesture recognition systems. Problems can be caused by a variety of factors, such as changing illumination and background clutter. We compare the most commonly used visual cues for hand segmentation, namely skin colour and background subtraction, applied both separately and combined...
متن کاملTracking and Segmenting People in Varying Lighting Conditions Using Colour
Colour cues were used to obtain robust detection and tracking of people in relatively unconstrained dynamic scenes. Gaussian mixture models were used to estimate probability densities of colour for skin, clothing and background. These models were used to detect, track and segment people, faces and hands. A technique for dynamically updating the models to accommodate changes in apparent colour d...
متن کاملAn efficient color compensation scheme for skin color segmentation
Skin color is a useful means for human face detection. In this paper, we propose an efficient color compensation method for skin color segmentation under varying lighting conditions. One of the major problems of using skin color is that a face region may not be detected under poor or uneven lighting conditions. Our approach considers the distribution of the color components of skin pixels and t...
متن کاملComputer Vision and Human Skin Colour
Computer vision based face and gesture recognition will allow future human computer interfaces to be more intuitive and user-friendly than traditional interfaces. A crucial processing step for the success of such systems is robust detection and tracking of faces and hands, which is frequently done by combining complementary cues, e.g., motion, shape, and colour. Skin colour is often used becaus...
متن کاملUser Localisation for Visually-Based Human-Machine-Interaction
physiologically motivated (see [15]) colour space corresponds to the deviation in illumination from typical daylight. By a process, the cluster is transformed so that its elongation will be along the achromatic axis. So we can ensure equal colour sensations under different lighting conditions (see 1st and 2nd figure below). The skin colour classification takes place within the RGB-colour-space ...
