adaboostcode，这是matlab环境下的adaboost代码，希望对各位有帮助。(adaboostcode, this is the matlab environment AdaBoost code, you want to be helpful.)

该压缩包里包括了一幅图像的位平面解，即一幅灰度图像可以分成八个位平面。利用它可以转化到彩取色图像中去，很有用处的。(The bag includes a compressed image bit-plane solution, that is, a gray image can be divided into eight bit-plane. Use it can be transformed into the color check color images, and useful.)

说明：  SAR-CS成像算法实现，包含运动补偿，速度估计，对0.15m实测数据成过像(SAR-CS imaging algorithms, including motion compensation, the estimated speed of 0.15m measured data into a cross as)

对图像采用DCT变换后，进行图像去噪的算法(Image denoise by DCT)

利用形态学的腐蚀运算提取图像边界 编写细化算法提取骨架的程序(Using morphology corrosion operation to extract image edgePreparation of thinning algorithm to extract the skeleton program)

vssamp算法，图像变步长自动匹配重构重构算法，基于samp算法，更快速有效的重构复杂图像(vssamp variable step size image reconstruction algorithm automatically matches reconstruction, samp algorithm based on more quickly and efficiently reconstruct complex images)

本程序用C语言在LSB上添加水印。最低有效位(LSB)是给这些单元值的一个二进制整数位位置，就是，决定是否这个数字是偶数或奇数。LSB有时候是指最右边的位，因为写较不重要的数字到右边位置符号的协定。它类似于一个十进制整数的最不重要的数字，它是在一个(最右边)位置的数字。(This program in C language to add a watermark on the LSB. The least significant bit (LSB) is a binary integer position to the value of these units, that is, to decide whether this number is even or odd. LSB is sometimes referred to as the rightmost bit, write a less important figure to the right location symbol Agreement. It is similar to the most significant digit of a decimal integer, it is the number in a (far right) position.)

说明：  特征检测与匹配的目标是识别一个图像中的关键点与另一个图像中的对应 点之间的配对。(The goal of feature detection and matching is to identify the key points in one image and the corresponding points in another image)

contourlet变换工具箱，很好用的。(contourlet conversion kit, the good.)

在梯度基础上使用加权平均提取指纹方向场然后使用高斯滤波进行平滑处理(Extraction of fingerprint orientation field using weighted average based on gradient)
