在matlab中实现标准条形码识别，设计带背景条形码图片分割与定位(To achieve standards in matlab bar code recognition, bar code design with the background picture segmentation and positioning)

基于图片的信息的隐藏与伪装，可以修改里面的参数使得其更好(Image-based information hiding and camouflage, you can change the parameters makes it better)

说明：  在神经网络中用迭代法对人脸图像进行压缩及恢复(Iteration in the neural network human face using image compression and restoration)

matlab 最优化处理的一些简单编程，以及附带若干个例子(Some simple matlab program optimization, and with some examples)

考虑你在哪里不同的传感器，桥上两侧的汽车造成的振动记录收集数据的情况。当你分析这些信号，则可能需要对齐。假设你有3个传感器以相同的采样速率工作，他们是造成同一事件的测量信号。(Consider a situation where you are collecting data different sensors, recording vibrations caused by cars on both sides of a bridge. When you analyze the signals, you may need to align them. Assume you have 3 sensors working at same sampling rates and they are measuring signals caused by the same event.)

粒子群优化算法(PSO)是一种进化计算技术(evolutionary computation)，有Eberhar博士和kennedy博士发明。源于对鸟群捕食的行为研究 ，PSO同遗传算法类似，是一种基于叠代的优化工具。 (Particle Swarm Optimization (PSO) is an evolutionary computation technique (evolutionary computation), and has Eberhar Dr. Dr. kennedy invention. Stems from the behavior of predatory birds, PSO with genetic algorithm is similar to an iterative optimization-based tools.)

matlab的工具箱，对于学习matlab有很大的帮助，很多很全~(matlab toolbox, matlab for learning a great help, a lot of very full ~)
