多变形填充
- 本程序是一个填充多边形的程序，采用逐行扫描，并判断是否在多边形内，若是，则填充颜色，反之不填充。-this procedure is a process filled polygons, progressive scan and determine whether the polygon, and if so, were filled with color, contrast not filled.
基于DCT变换的图像编码方法研究
- 本文结合DCT变换的特性，利用分形的Peano一hilbert扫描曲线，对基于DCT变换的图像编码方法进行了研究，并提出了改进方法。主要工作分为两个部分: 一是在分块DCT基础上的改进。对分块后生成的各图像块矩阵，不直接作二维DCT变换，而是先进行扫描，使之重排成一维向量，再进行一维DCT变换，这样可以减少运算量。 其次是对层次余弦变换编码部分的改进。使用层次DCT变换与零树编码相结合的方法，并在扫描编码过程中，按Peano一hilbert扫描顺序进行编码。这样不仅可以减少“块效应”，而且可以加

- 本实验要求编写一个计算图像直方图的程序并要求讨论直方图均衡化技术，最后对图3.8（a）进行均衡化处理。直方图是多种空间域处理技术的基础，直方图操作能有效的用于图像增强。在实验中根据直方图对应的离散函数可以编写出计算一个图像直方图的函数，直方图均衡化则是借助于直方图灰度变换实现灰度映射从而达到图像增强的目的。实验通过得到原始图像的直方图，直方图均衡化变换函数图和增强后的图像增强后图像的直方图这些实验数据来解释图像被增强的原因。,In this study requested to prepare
