2ASK-2FSK-2PSK-lmodulation

特别经典的俄罗斯方块matlab程序！图形不错，界面也做得很好，共享给大家一起学习！(In particular the classic Tetris matlab program! Good graphics, the interface they have done well to share for everyone to learn!)

- K means algorithm is performed with different initial centroids in order to get the best clustering. - The total cost is calculated by summing the distance of each point to its cluster centre and then summing over all the clusters.Based on the minimum overall cost achieved during each iteration of iterKMeans the pixel assignment to their respective clusters are made and final compressed image is obtained. This algorithm will run slower as the number of clusters , size of the image and number of iterations increase.

说明：  全程:近地倾斜轨道至地球静止轨道转移方案MATLAB程序包，顾名思义。(As the name implies, the MATLAB program package for the transfer scheme from near-Earth tilt orbit to geostationary orbit.)

图像中值滤波，利用中值滤波和低通滤波进行比较，分析PSNR，得出性能差别(image filtering, using median filter and a low-pass filter, PSNR analysis, the performance differences come)

Large Area DEM Generation Using Airborne LiDAR Data and Quality Control

说明：  在很多图像处理的过程中，需要判别一个图像的清晰度，和图像分割结果的优劣，于是就引出了信息熵的概念，绝大多数时候，它都被用来作为评价图像的一个量化标准。(In many image processing processes, it is necessary to distinguish the clarity of an image and the result of image segmentation, so the concept of information entropy is introduced. Most of the time, it is used as a quantitative standard to evaluate the image.)

说明：  一套非常漂亮的图片站程序，以前本人用过的，而且利于排名！(A very beautiful picture at stations, previously I used, but also helps to rank!)
