Color Image Enhancement Techniques: A Critical Review Abstract Image enhancement is one of the key issues in high quality pictures such as digital camera and HDTV. Since Image clarity is very easily affected by lighting, weather, or equipment that has been used to capture the image. These conditions lead to image may suffer from loss of information. As a result, many techniques have developed known as image Enhancement techniques to recover the information in an image. This paper presents a literature review on some of the image Enhancement techniques for color image enhancement like, Contrast Stretching, Histogram Equalization and its improvement versions, Homomorphic Filtering, Retinex, and Wavelet Multiscale Transform. Comparison of all the techniques concludes the better approach for its future research

处理lasso regression。 使用stochastic Markov property。(Algorithm for solving the Lasso problem: 0.5* (y- X*beta) *(y- X*beta)+ lambda* ||beta||_1 where ||beta||_1 is the L_1 norm i.e., ||beta||_1 = sum(abs( beta )) We use the method proposed by Fu et. al based on single co-ordinate descent. For more details see GP s notes or the following paper: Penalized Regressions: The Bridge Versus the Lasso Wenjiang J. FU, Journal of Computational and Graphical Statistics, Volume 7, Number 3, Pages 397?416, 1998 )

本程序实现2维TM波FDTD仿真,此程序用PML设置吸收边界条件(This procedure to achieve two-dimensional TM wave FDTD simulation, this procedure is set with the PML absorbing boundary condition)

基于C的Matlab函数功能扩充组合代码(Based on the C to expand the portfolio of Matlab Function code)

sensitivity calculus : output variation vs parameter variation

本程序生成的图片容量大概3M左右，所以对计算机配置要求较高。(This program generates pictures capacity probably about 3M, so the higher the computer configuration requirements.)

使用bp预测模型，通过matlab变成实现对现实生活进行应用于预测。(the real example for the bp model to forecast something)

matlab的滤波器设计，包括FIR窗函数设计法，IIR的双线性变换法和冲击响应不变法，比较的全面，非常好的学习资料 (matlab filter design, including the window function design method FIR, IIR' s bilinear transformation method and the same impulse response, comparison of the overall, very good learning materials)

说明：  在通信系统中的多天线选择技术，用MATLAB进行仿真，生产信噪比与误码率的图像。(MIMO)
