Description: The Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG are finalising a new standard for
the coding (compression) of natural video images. The new standard [1] will be known as H.264 and
also MPEG-4 Part 10, “Advanced Video Coding”. This document describes the transform and
quantization processes defined, or implied, by the standard. Platform: |

Description: 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。
3、点击转换按钮，可以看到经过变换量化和逆量化逆变换过程以后输出的图像以及显示输出图像的PSNR值（保留小数点后6位）和默认4x4块号为0的原始各像素值、整数变换后的值、量化后、逆量化后、逆变换后的值。
4、可以手动改变块号，块号的范围为0-6335，超出范围会弹出对话框提示。然后单击“输入块号”按钮即可显示此块号对应的原始各像素值、整数变换后的值、量化后、逆量化后、逆变换后的值。

1, first press the "Open YUV" button, select a format for the CIF of the 4:2:0 YUV image (the default YUV image format 4:2:0 CIF format). Selection is complete, you can see displayed in the input image.
2, enter the QP value, QP is an integer between 0-51 values out of range, will pop-up dialog box prompt. QP default is 28. Note: When changing the QP value is 0, that is not quantified, then click the convert button to show the PSNR values of the PSNR values shall be the input image.
3, click the Convert button, you can see through the transformation inverse quantization and inverse quantization output of the image after the transformation process and display the output image PSNR values (retention decimal 6), and the default 4x4 block No. 0 of the original values of each pixel , int Platform: |
