This book, is the most competitive book in the field of neural network I have ever seen. It reports the latest progress in the application to image processing. These include, image denoising, image segmentation, image enhancement, and etc. In this book the readers can get (1) the basic principles of pulsed coupled neural network; (2) how to apply PCNN on image processing; (3) the state-of-the-art techniques and algorithms. Let us join the pulse coupled neural network specially those who are doing image processing jobs.
