摘要： A method and apparatus evaluates quantization matrices used in video codec systems. Two primary factors are considered in making these estimates. The first is the human visual system contrast sensitivity function. This function measures how well a quantization matrix fits human visual characteristics. The second factor is a typical viewing setting, such as a range of typical viewing distances. For consumer use, the viewing range is one to four times picture height. For professional use, it is assumed the viewing range is one-half to three times picture height. The quantization matrix used in a video codec system defines the quantization step for different frequency bands. This quantization step is essentially equivalent to the allowable error in a frequency band. The present invention evaluates the quantization matrix for its effectiveness in hiding distortion errors. By using this evaluation scheme, the quantization matrix can be modified as needed, and the overall performance of the quantization matrix in a video codec system is improved substantially.
摘要翻译：方法和装置评估在视频编解码系统中使用的量化矩阵。在作出这些估计时，考虑了两个主要因素。第一个是人类视觉系统的对比敏感度函数。该函数测量量化矩阵适合人类视觉特性的程度。第二个因素是典型的观看设置，例如典型观看距离的范围。对于消费者来说，观看范围是图像高度的一到四倍。对于专业使用，假设观看范围是图像高度的一半到三倍。在视频编解码器系统中使用的量化矩阵定义了不同频带的量化步长。该量化步骤基本上等于频带中的容许误差。本发明评估了其在隐藏失真误差方面的有效性的量化矩阵。通过使用该评价方式，可以根据需要修改量化矩阵，并且在视频编解码系统中的量化矩阵的总体性能得到显着提高。

摘要： A coding method for coding a picture in a moving picture with a processor configured to code, on a block-by-basis, each picture in the moving picture, to generate a coded stream. The processor transforms each picture into coefficients representing spatial frequency components and quantizes the coefficients with a quantization matrix. Identification information identifying the quantization matrix is provided in the coded stream in predetermined units to reduce the amount of data to be coded. The processor is configured to use a coded quantization matrix for a chroma component rather than a default quantization matrix.
