matlab实现的三维直方图统计。用来统计数据的三维直方图。可适用于任何三维数据的统计。(matlab code to deal with 3d hist.)

说明：  facet边缘检测的matlab源代码,是基于二阶模型，只要运行最后一个hhh.m就可以了(facet Edge Detection Matlab source code is based on second-order model, as long as the last one run on the hhh.m)

256色显示文件。在DOS环境下用256原色显示BMP格式的图片。(256-color display documents. In the DOS environment display with 256 color BMP format picture.)

说明：  视频转帧预处理 ，应用于红外图像序列处理，为后续处理提供便宜。(Video frame preprocessing, applied to infrared image sequence processing, provides cheaper for subsequent processing.)

说明：  该方法在传统的极化SAR滤波Lee方法上增加了自适应窗口处理以及滤波参数预估计等步骤，有效的提高了传统的滤波方法的抑制相干斑的能力，同时能够很好的保持极化SAR图像的极化散射特性。(in the traditional method of increasing polarization SAR Lee adaptive filtering window processing and pre-filtering parameters estimation step, effectively improve the traditional filter method of inhibiting the ability to spot coherent while being able to maintain a good polarization scattering characteristics of SAR images.)

灰度图像直方图的计算，超级好用的啊，可以通过它获得图像的分形维数等等，内存小，功能大(Gray image histogram calculation, super nice ah, you can get through it the fractal dimension of the image, and so on, the memory is small, functional large)

jpeg编解码程序，c语言的，很好用，直接用vc++打开编译便可使用。很好移植(jpeg decoding process, c language, useful, open directly vc++ compiler can be used. Good transplant)

将曲线轮廓中的B-样条曲线通过最小二分法转换成一组能保持曲线轮廓形状的小折线。这样，原有的字体轮廓数据就从用曲线轮廓表示转变为用多边形表示，即用一组点及其先后顺序来描述轮廓。(Profile to Polygon)

深度学习的Toolbox,使用mnist_uint8手写字数据库，适合初学者使用。(Deeplearning of the Toolbox, use mnist_uint8 handwritten word , for beginners.)

JSteg隐写技术matlab实现代码--基本思想：用秘密信息比特直接替换JPEG图像中量化后DCT系数的最低比特位，但若量化后DCT系数为0或者1，则不进行处理。（DCT系数的LSB嵌入） (JSteg steganography matlab code- the basic idea: direct replacement with the secret information bits JPEG image quantized DCT coefficients in the least significant bit, but if the quantized DCT coefficient is 0 or 1, no processing. (DCT coefficients LSB embedding))
