In this paper, a new face detection approach based on skin color segmentation is presented. First, the color image is converted into YCgCrcolor space from RGB, because the performance of clustering is excellent in YCgCr color space. We get the segmented image by using the algorithm of support vector machine in YCgCr color space. Finally, we offer a face verification algorithm according to the geometric...
To simulate tunnel environment in an underground mine during a fire disaster, a new computer simulation method based on cellular automata and particle system theory is proposed. Considering special environment in an underground mine's tunnel system, a cellular automata model, which neighborhood radius is variable to simulate flame spreading is employed; simultaneously a smog model based on particle...
