用MATLAB实现将灰度图转换为彩色图（伪彩色）(Gray into color image by the use of MATLABP（seudo-color）)

retinex阴影去除 non linear processing on the image by the commercial camera used Sensors are not Dirac Delta Functions but narrow band Approximate invariant angle is obtained by the entropy minimization mehtod. Exact angle can only be found by camera calibration method(retinex shadow removing，non linear processing on the image by the commercial camera used Sensors are not Dirac Delta Functions but narrow band Approximate invariant angle is obtained by the entropy minimization mehtod.

变步长自适应滤波算法，对VS—LMS算法进行了改进，建立了步长因子μ与误差信号e（n）之间另一种新的非线性函数关系．理论分析和计算机仿真结果表明，该关系不仅具有原有算法收敛速度快的优点，而且在低信噪比环境下比原有算法具有更好的抗噪声性能．(The variable step size adaptive filtering algorithm is discussed, and the VS-LMS algorithm is improved. A new nonlinear function relation between the step size factor μ and the error signal e (n) is established. Theoretical analysis and computer simulation results show that the proposed algorithm not only has the advantages of high convergence speed of the original algorithm, but also has better anti- noise performance in the low SNR environment than the original algorithm.)
