对一维信号，用正交重叠变换做DCT和逆DCT(Of one-dimensional signals, using orthogonal lapped transform DCT and inverse DCT to do)

说明：  DensePose用深度学习把2D图像坐标映射到3D人体表面上，再加上以每秒多帧的速度处理密集坐标，最后实现动态人物的精确定位和姿态估计。该技术集目标检测、姿态估计、目标部分/实例分割等多种计算机视觉任务于一身的一个综合问题。(DensePost maps 2D image coordinates to 3D human body surface by in-depth learning, and processes dense coordinates at the speed of multiple frames per second. Finally, it realizes precise positioning and attitude estimation of dynamic characters. This technology integrates many kinds of computer vision tasks, such as target detection, attitude estimation, target part/instance segmentation, etc.)

适合初学图形学的人,都是基本的绘图与填充及图形变换,贝页丝曲线的绘制.(graphics suitable for beginners who are basic drawing and filling and graphic transformation, Pui-page wire drawing curves.)

一个较好效果的彩色图像合成代码(分左右两个视窗,很好用(A good effect of color image synthesis code (about two Windows, very useful)

说明：  图像的DCT变换 提取高频分量 和低频分量 (DCT change)

比较简单的jpeg编码解码程序.( Compared with simple jpeg code decoding procedure )

医学图像处理，主要用于图形形态学，如腐蚀、膨胀以及开、闭运算。(Medical image processing, mainly for graphics morphology, such as erosion and dilation as well as opening and closing operation.)
