Stationary hand gesture recognition can be applied in a variety of domains such as human-computer interaction (HCI), remote control, virtual reality etc. Hand gesture recognition is mainly the study of detection and recognition of various hand gestures like Sign Language hand gestures, by a computer. This work is focused on three main issues in developing a gesture recognition system. These are (i) Threshold (ii) illumination normalization (iii) user independent gesture recognition based on fusion of Moments. It is very demanding to segment hand regions from the static hand gesture color images, due to unreliable light conditions and composite background. Since skin pixels can vary with different explanation condition, to find the range of skin pixels, becomes a hard task in case of color space based skin color segmentation. These methods propose a learning algorithm based on customized clustering expanse to remove person skin color regions from the stationary hand gesture color descriptions. To improve the performance of classification, two feature synthesis strategies have been proposed in this work.
