变换编码 meaning in English
transform coding
transformational coding
transition coding
Examples
- In the second part : the emphasis of this part lies in discussing subband coding , wavelet transform coding and fractal coding , whose coding functions are better than the coding of having dct as the core
因此本文第二部分重点讨论了编码性能要优于离散余弦编码的子带编码、小波变换编码和分形编码。 - An advantage of wavelet - based video compression is that it offers more graceful image degradation at high compression ratios , and it also eliminates the block artifacts seen in dct compression
由小波变换编码实现的视频压缩在具备高压缩比的基础上，仍拥有较高的主观视觉效果，避免了由分块dct变换引起的方块效应。 - Thirdly dct is implemented using chen fast dct algorithm . we transform float - point arithmetic into fixed - point arithmetic , which meeting the precision requirements of the ieee 1180 standard , to accord with fixed - point c6201 dsps
随后在dct变换编码中，采用chen快速dct算法，在保证idct精度符合ieee1180标准条件下，将浮点dct系数转化为与c6201定点dsps运算单元相适应的定点系数。 - This paper introduces the process of transform coding and the principle of still picture & moving picture compression and the standards of jpeg / mpeg - 2 and practical skill of the standards from the angle of the application and network in the development of dvd in front
本文前半部分主要从dvd的应用及未来网络化发展的角度，论述了变换编码、静止与活动图像压缩原理、 jpeg mpeg - 2标准和实用技术。 - Digital image processing techniques have been being used more and more widely in many fields such as multimedia , the internet , television and fax , etc . image compression is one of the most important key techniques in image processing
数字图像处理技术在多媒体、因特网、电视、传真等领域的应用越来越广泛。图像压缩是数字图像处理中最重要的关键技术之一，传统的图像压缩方法有预测编码、变换编码和矢量量化等。
