This paper presents a fast method for detecting the center of the eye in color face images using different color spaces. Specifically, this method consists of three stages. First, a color face image is transformed from the RGB color space to the YUV color space to extract the U color component image, whose binary image is utilized by projection functions to roughly locate the eye boundaries. Second,...
Eye detection is an important initial step in an automatic face recognition system. We present in this paper a real-time accurate eye detection method using color information and wavelet features together with a new efficient Support Vector Machine (eSVM). In particular, this method consists of two stages: the eye candidate selection and validation. The selection stage rejects 99% of the pixels through...
Coordination of multiple autonomous robots is a typical research problem in Multi-agent systems. The distributed agent models that represent the supervisory controllers of autonomous soccer robots are capable of communication, interaction and collaboration. By introducing the multi-agent based control architecture, the soccer robots perform seamless team cooperation to achieve the desired mission...
The hand gesture is the most common and natural way for human daily interaction. In this paper, we propose a novel approach to hand extraction based on active skin color model. The skin color model is first built by the non-linear transformation in YCbCr color space. Then the obtained model is applied to hand segmentation. Hand feature is extracted by calculating the seven moments of hand segmentation...
