图像阈值分割，基于matlab的二维Renyi熵算法的灰度图像分割(Image threshold segmentation, matlab based two- dimensional Renyi entropy algorithm gray- scale image segmentation)

说明：  图片自适应二值化处理，二值化处理使用简单方便。(Adaptive binarization image processing, binary processing easy to use.)

insar图像数据，envisat卫星单视复数数据，可在matlab中直接打开(insar data, envisat single look complex data, which can be opened directly in matlab)

一个医学图像配准的源程序，希望对大家有用(A medical image registration of the source, in the hope that useful to everybody)

特征提取是图像配准的重要步骤，使用Harris角点检测算法实现图像拼接。(Feature extraction is an important step in image registration, using Harris corner detection algorithm for image mosaic.)

用于将视频文件转换成帧图像、帧图像转换为mat语言等(Converts a video file to a frame image, then converts it into a number matrix and the inverse process)

说明：  在一图像中加入噪声，是超分辨率中的一个重要步骤哦(noise)

说明：  基于背景差分法和帧间差分法的目标跟踪 应用了二维滤波，效果较好(Based on background difference and frame difference method applied to two-dimensional target tracking filter, better)

此代码是小波零树算法的matlab实现程序，子程序较为齐全，包括最后计算压缩图像的峰值信噪比和压缩效果的源码。(This code is the wavelet zero-tree algorithm matlab implementation procedures, subroutines are more complete, including the final calculation of the peak signal to noise ratio and the compressed image compression source.)

实现图像的二阶巴特沃斯(Butterworth)低通、高通滤波器，高斯低通、高通滤波器(Butterworth LPF、Butterworth HPF、Gaussian LPF、Gaussian HPF)
