MATLAB 计算医学图像的配准，融合 基于SIFT方法的配准()

用matlab实现标准四步相移条纹,可自己设定条纹的高度和宽度；最后得到包含相位信息的条纹包裹图。(Using matlab to achieve the standard four-step phase shift stripes, stripes can set their own height and width finally get the phase information contained stripes wrapped map.)

说明：  实现图像模糊和恢复，有逆滤波恢复方法、傅里叶变换(Image blur and restoration are realized by inverse filtering and Fourier transform)

局部投影去噪 自己编的 调试已经成功 拿来给大家借鉴 对象是混沌信号(Local projective denoising their own series of debugging has been successfully brought to everybody' s reference object is a chaotic signal)

自适应中值滤波器 该滤波器与中值滤波器相比，功能有很大的改善，但函数要复杂了很多(adapt median filter ,this filter compared with median filter, it is much improved in the resulted image.)

说明：  matlab编写计算直边图像的点扩散函数PSF(Compiling Point Spread Function ( PSF) for Computing Straight Edge Images with MATLAB)

非常不错的IDL实现的放大缩小代码，希望能给大家带来方便(Achieved a very good zoom IDL code, I hope that it brings convenience)

给予matlab的JPEG压缩程序，包含原始压缩图片，程序对灰度bmp图片进行JEPG编码，压缩成以0101形式的编码。JPEG编码先把图象色彩RBG变成亮度Y和色度Cr、Cb，它利用人的视觉对色度不敏感的特点，减少一部分色度数据，以达到压缩。 JPEG采取多种编码方式，包含有行程编码(Run Length Coding)和哈夫曼(Huffman)编码，有很高的压缩比。在编码前，先对数据进行分块，离散余弦变换（DCT）及量化，保留能量大的低频信号，丢弃高频信号以达到压缩。(Given to the JPEG compression matlab program, contains the original compressed image, the program of the grayscale bmp picture JEPG encoded, compressed into a 0101 form of encoding. RBG color coded JPEG image into a first luminance Y and chrominance Cr, Cb, which uses the human visual characteristics is not sensitive to the color, reduce the number of color data to achieve compression. Take a variety of JPEG encoding, includes length coding (Run Length Coding) and Huffman (Huffman) coding, a high compression ratio. In the code before the data block, discrete cosine transform (DCT) and quantization, to retain a large low-frequency signal energy, discarding high-frequency signals in order to achieve compression.)
