计算局部形状描述符梯度方向直方图（HOG），直接输入图像即可用。(Calculate the local shape descriptors gradient orientation histogram (HOG), the input image can be used directly.)

rgb颜色空间与hsi颜色空间转换的一段MATLAB代码。(a matlab code rgb space to hsi space or return.)

相位编组提取长直线的强弱文理，用于灰度图像明显的图像的处理(Marshalling phase extraction strength ARTS long straight, clear images for grayscale image processing)

用PHD滤波的方法实现多目标跟踪，及对PHD滤波性能的检测。(PHD filter method using multi-target tracking, and performance testing for the PHD filter.)

本代码实现了对高光谱遥感图像进行混沌序列置乱加密，其中包括读取三维立体遥感图像、混沌加密以及灰度直方图绘制(This code implements the hyperspectral remote sensing images chaotic sequence of scrambling encryption, including reading the three-dimensional sensing image, and histogram drawing Chaotic Encryption)

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.)

填充区域图像，设置填充区域，填出图像的颜色(Filled regional images, set fill area, fill in the color of the image)

读取图像，将RGB图像转化为灰度图像，显示并保存(The RGB image is transformed into gray image)

这是角点检测的程序，图像中所有凹凸点都可以检测到，并在二值图像上显示出来，效果不错。直接运行corner.m即可(Corner detection program, the result is good)

对飞机进行边缘检测，阈值分割。从而达到图像感兴趣区域提取的目的，能使得图像中的飞机以黑白形式清晰地单独显示出来(Aircraft edge detection , thresholding . So as to achieve the purpose of extracting image regions of interest , can make the image appear as black and white aircraft clearly separate)
