摘要

宽高比是视频图像的宽度与其高度的分数关系。由于历史和其他一些因素的影响，有很多不同宽高比的视频格式，对宽高比转换的要求越来越迫切。本文介绍了文献中已发表的长宽比转换方法，包括裁剪法、展开法等，并给出了实验结果，说明了每种转换方法的优缺点。

A Comparative Review of Aspect Ratio Conversion Methods

The Aspect ratio is the fractional relation of the width of a video image compared to its height. Because of the historical and some other factors, there are so many video formats with different aspect ratios and the conversion of aspect ratio is required more and more imminently. The paper introduced all the aspect ratio conversion methods published in literatures, including cropping method, expanding method and so on, and presented experiment results to demonstrate the advantages and disadvantages of each conversion method.
