to do KNN classifier

For all classifier needs feature classification object .Here the program for height and width feature taken hand image.This program suitable for any single object in the image. input gray_img : input hand image or any measure image like 2d with 0 to 255 intensity output height : pixel count of height width : pixel count of width out_img : segmented image with line for height and width hand_height_width function implements hand height and width of the image using the method outlined in: calculate the hand height and width value for gray image. In Proceedings of the Information Sciences 275 (2014) 45–56. Hand shape identification on multirange images. [ height width out_img ] = hand_height_width ( gray_img ) function is to find the hand height and width value of the image. The input is given to the gray scale image.

对ising模型的模拟，这是二维的情况，对于学物理的人很重要的。(Ising model for the simulation, which is two-dimensional case, for physics, it is very important.)

说明：  利用Matalab软件分别编写子函数实现数字图像压缩及解压缩处理，并统计分析压缩处理算法所能够实现的压缩比及解压图像和原始图像间的均方根误差。(Functions were written by Matalab software for digital image compression and decompression processing, and statistical analysis of compression algorithms to achieve the compression ratio and decompression images and root mean square error between the original image.)

说明：  对离散数据运用最小二乘法进行椭圆拟合，运行过了觉得还不错就上传了。(Discrete data on the use of least squares method for ellipse fitting, run over a feel good on the uploaded.)

说明：  短时傅里叶变换，通过加窗函数，切割，做到精细化处理(Short time Fourier transform, through windowing function, cutting, achieve fine processing)
