说明：  在N=128时采用次优化迭代算法的PTS法与普通PTS法的PAPR性能比较。仿真参数：QPSK调制，V=4，P=4，取 。从程序的运行时间可知，采用次优化迭代算法，PTS法的复杂性可以大大降低。(In the N = 128 used sub-optimal iterative algorithm method and the general PTS PTS PAPR performance comparison method. Simulation parameters: QPSK modulation, V = 4, P = 4, to take. We can see from the program' s running time, using sub-optimal iterative algorithm, PTS method can greatly reduce the complexity.)

从X光片中提取出骨头影响，并对其区域进行标注。(X-ray film extracted from the bones of the impact, and its region mark.)

there is some code in matlab that will provide help in the field if digital image processing.it includes the code of extracting region of interst, median filter, nearest neighbour point sampling technique, negative of an image etc. and it is done by myself because i am doing becholar of computer science.it does not include any copyrighted content.i hope it will help thoes people that required help in the field of digital image processing.
