The paper proposed a robust optimum thresholding method based on local intensity mapping(LIM), class uncertainty and region stability theories to segment fuzzy and noisy images. First of all, the intensities of an image would be mapped into another intensity space by LIM which could decrease the influence of noise and uneven intensity distribution. Then, the intensity-based class uncertainty is applied...
Real-time hand and face localization is a challenging problem in many application scenarios such as face and gesture recognition in computer vision and robotics. This paper proposes a robust method which can locate multiple faces and hands simultaneously under the changing environment of light illumination and complex background in real time by using skin-color detection and K-means in conjunction...
In this paper, an integrated video surveillance system for robust tracking is introduced. In the blob detection part, an optical flow algorithm for crowded environment is studied experimentally and a comparison study with respect to traditional subtraction approach is carried out. In the segmentation part, different algorithms are fused to develop a hybrid algorithm for stable segmentation, and validation...
