说明：  几种前向神经网络的应用实例，用matlab编的源代码(Several prior to the application of neural network, using matlab made the source code)

This is very important code for image segmentation comparisons, this code calculates RI, GCE and VI for segmentation comparisons.

主要应用于图像分割，基于分水岭分割算法的图像分割(The ICON partitions)

说明：  BP神经网络算法，BP(back propagation)神经网络是一种按照误差逆向传播算法训练的多层前馈神经网络，是应用最广泛的神经网络。(BP (back propagation) neural network is a kind of multilayer feedforward neural network which is trained according to the error back propagation algorithm. It is the most widely used neural network.)

说明：  应用MATLAB实现眼睛的定位检测程序，大家分享看看(Application of MATLAB to achieve positioning of the eye detection process, we share a look)

比较为基础的相关使用空间域使用两个伪序列块处理 为“0 1”，另一个是“1”水印恢复(Comparison-Based Correlation using block processing in the spatial domain Uses two PN sequences one for a "0" and another for a "1" Watermark Recovery)

this matlab code about corrent channel

用Matlab实现的LDPC编码程序，希望对大家有用(Matlab achieved with LDPC coding procedures, we hope to be useful)
