H264-DCT-Quanter
- H264中的整数DCT变换编码及量化代码,并附有原文的DCT编码、量化的说明文档。本源码从X264及JM中抽取后整理得来,并用原文档中的示例数据进行了测试,与原文档结果完全一样,是学习H.264不可多得的参考资源. -H264 in the integer DCT transform coding and quantization code, together with the original DCT coding, quantitative descr iption of the doc
DctQuant
- 工程名为DctQuant,编程实现了一帧CIF格式4:2:0的YUV图像的H.264的整数变换、量化以及逆量化、逆变换。具体的功能表述如下: 1、首先按“打开YUV”按钮,选择一帧格式为CIF的4:2:0的YUV图像(默认的YUV图像的格式为4:2:0的CIF格式)。选择完成后,可以看到显示的输入图像。 2、输入QP值,QP是0到51之间的整数值,超出范围,会弹出对话框提示。QP默认为28。注意:当改变QP值为0时,即没有量化,则点击转换按钮显示出的PSNR值即为输入图像的PSNR值。
imrotate_my
- 一个空间点P绕一个中心点C旋转可用接续的三个变换来实现:第1个变换平移点C到坐标系原点位置,第2个变换将点P绕原点旋转,第3个变换平移点C回到其相对于坐标系原点的原始位置。当原始图像点乘以变换矩阵,得到新的图像位置点时,其位置可能不是整数值,该位置的灰度值需要通过灰度插值获得。在不改变输出图像大小的情况下,超出原始图片范围的区域,MATLAB原有函数imrotate的处理方法为将其灰度值全部置零,本文通过取模操作对超出区域进行了另外一种控制方法imrotate_my函数,能够较好的显示出图像旋转
