- 数字图像处理实验 根据原图像的直方图,发现背景和目标的分割值大约在130左右,并将灰度图像转为二值图像,分割效果比较理想。 图像处理实验(六)图像压缩与编码 实验目的: 学习JPEG压缩编码 实验内容: 一.实现基本JPEG的压缩和编码分三个步骤: 1. 首先通过DCT变换去除数据冗余; 2. 使用量化表对DCT系数进行量化; 3. 对量化后的系数进行Huffman编码。-digital image processing experiments based on
SMQTcode
- 根据icip会议2005年度的一篇文章编写的matlab程序。包含有效果图。 运用smqt(连续均值量化变换)算法进行灰度图像增强。它比传统方法(直方图均衡化处理)的优点在于可以保证增强后图象的直方图波形不变,可以展现图象的底层结构,自动集中改进图象细节。是一种新的效果更好的灰度图象增强算法。-under icip 2005 annual meeting of an article prepared by the Matlab procedures. Includes map results
