Recent researches indicate that pulse coupled neural network can be used for image processing, such as image segmentation and edge detection effectively. However, up to now it has mainly been used for the processing of gray images or binary images, and the parameters of the network are always adjusted and confirmed manually for different images, which(More)
In recent years, the constrained optimization problems have become a hot topic among the interest of scholars. In this paper, a new improved artificial immune algorithm is proposed and then used for solving constrained optimizations problems (COPs). This algorithm will treat these COPs as multi-objective optimization problems, and it is based on the concept(More)
Based on bidirectional lamp tracking and utilizing performances of Monte Carlo method, A novel algorithm is proposed here which makes it easy for an user to simulate the bright region of lamp-source on the testing screen. Comparing with the forward lamp integral method, this model is not only applicable to reflectors of any figure but also far more rapid(More)
