摘要翻译：
我们提出并讨论了将矩形图像转换为椭圆区域的不同算法。我们主要关注使用具有显式和可逆方程的数学映射的方法。其关键思想是从正方形和圆盘之间的可逆映射开始，然后扩展到处理矩形和椭圆。这个扩展可以通过简单地移除偏心并在使用选定的正方形到圆盘映射后重新引入它来完成。

英文摘要：
  We present and discuss different algorithms for converting rectangular imagery into elliptical regions. We mainly focus on methods that use mathematical mappings with explicit and invertible equations. The key idea is to start with invertible mappings between the square and the circular disc then extend it to handle rectangles and ellipses. This extension can be done by simply removing the eccentricity and reintroducing it back after using a chosen square-to-disc mapping.
