这本关于元胞自动机的教材结合了matlab例程，讲解生动，读者朋友可以自己尝试建立自己的元胞自动机模型(This textbook on cellular automata combines the MATLAB routine with a vivid explanation that readers can try to build their own cellular automata model.)

联合检测的代码，学习联合检测的好方法，这里和大家一起共享(Joint detection code, a good way to learn the joint test, to share with everyone here)

Simple but effective example of "Region Growing" from a single seed point. The region is iteratively grown by comparing all unallocated neighbouring pixels to the region. The difference between a pixel s intensity value and the region s mean, is used as a measure of similarity. The pixel with the smallest difference measured this way is allocated to the region. This process stops when the intensity difference between region mean and new pixel becomes larger than a certain treshold
