数字图像处理matlab版自编函数，包括边缘处理等各种函数(The various functions of the digital image processing matlab version of the self-function, including edge treatment)

用于计算相机外参数，即CCD像素坐标与三维世界坐标的对应关系，输入参数是世界坐标标定点对，输出外参数矩阵(Outside the parameters used to calculate the camera, that the correspondence between CCD pixel coordinates and the coordinates of the three-dimensional world, the world coordinate input parameter calibration point right, outside the parameters of the output matrix)

Chaotic maps. Matlab simulation.

算地震动，加速度，位移和速度，很好用的，呵呵。大家给力啊。(Considered ground motion, acceleration, displacement and velocity, the good, huh, huh. We can give power ah.)

用Matlab的GUI设计的能打开摄像头，进行监控的报警，就是停止的功能没有开发好还，共享一下。(Using GUI to design Matlab can open the camera, monitoring alarm, is to stop function did not develop good also, sharing what.)

说明：  图像特征提取，计算图像的7个Hu不变矩特征，matlab例程(Seven Hu invariant moments features of images)

match two images and extract features.

this source code use to recognize iris using ANN method

matlab实现商标文字分割~第一部分计算列梯度差，计算每个像素的列方向一定范围内（n）最大值和最小值的差距,统计该差值超过某一设定域值T的像素的个数，并将该统计个数存在 GY 向量。，第二部分计算行梯度差，计算每个像素的行方向一定范围内（n）最大值和最小值的差距，统计该差值超过某一设定域值T的像素的个数，并存在 GX 向量(matlab text segmentation ~ realize trademarks calculations are shown in the first part of the gradient difference, calculated for each pixel column direction of a certain range (n) the difference between maximum and minimum values, statistics of the difference exceeds a certain threshold T set of pixels of a few, and the statistics of the number of vectors exist GY. , The second part of the calculation line gradient difference, calculated for each pixel within a certain range direction (n) the difference between maximum and minimum values, statistics of the difference exceeds a certain threshold T set the number of pixels, and the existence of GX Vector)
