角点的计算calculate the curvature of image(calculate the curvature of image)

说明：  该程序给出了OFDM信号以及频谱分析，也插入了保护间隔(the procedure given OFDM signal and spectrum analysis, insert a protective partition)

该程序介绍了有关八叉树编码的基本编程知识，对于初级学者易懂易学。(This program introduces the octree encoding basic programming knowledge, which ishelpful for junior scholars to understand.)

多径效应的时域表示实际上就是不同路径来的信号存在随机的时延差。对于抗其它扩频信号干扰性能，及抗多址干扰性能。我们这里考虑简单的情况，只考虑一个用户干扰的情况，说明其具有抗多址干扰性能就行。(Multipath effect is actually a time domain representation of the signal path to the existence of different random time delay difference. Other spread spectrum signal for the anti-interference performance, and anti-MAI performance. Here we consider the simplest case, considering only one user interference, indicating its performance with anti-multiple access interference on the line.)

very good excellent amazing

对位图图像利用JPEG标准进行正交变换、量化、扫描从而达到压缩，同时解压显示其压缩图像。(Bitmap image using JPEG standard orthogonal transformation, quantization, scanning to achieve the compression, and decompression display the compressed image.)

说明：  数值分析-函数逼近-插值法-lagrange插值法的实现(- Function approximation- interpolation-lagrange interpolation achieve numerical analysis)
