Thus, encoding an image by fractal techniques consists of finding an appropriate contractive transformation whose fixed point is the best possible approximation of the original image.

因此，一幅图像的分形编码就是寻找一个合适的压缩仿射变换，它的不动点是原始图像尽可能好的近似。

Some fixed point theory of fractional linear transformation is discussed and it is shown that one kind of transformation from unit circular to unit circular has only some real fixed points.

本文讨论了分式线性变换不动点理论，并证明了一类单位圆到单位圆的分式线性变换仅有实不动点。

Unified fixed point coordinate transformation (UFP-CT), and a novel zero steady-state error current control method for active power filter (APF) based on UFP-CT were proposed.
