Image segmentation is an important part of image processing. For the disadvantages under multiple thresholds such as long time and poor quality, improved cuckoo search (ICS) proposed for multithreshold strategy. Firstly, model based on maximum entropy threshold described, secondly, algorithm by using chaotic initialization population to improve diversity solutions, optimizing step size factor p...

Back propagation neural network (BPNN) algorithm is a widely used technique in training artificial neural networks. It is also a very popular optimization procedure applied to find optimal weights in a training process. However, traditional back propagation optimized with Levenberg marquardt training algorithm has some drawbacks such as getting stuck in local minima, and network stagnancy. This...
