Paper Abstract

Based on the classical log-polar transformation (LPT), the variable parameter log-polar transformation (VPLPT) is proposed. In the new algorithm, the size of uniform sampling central area is freely adjustable according to different vision task and its high resolution is reserved. The peripheral area is processed with log-polar transformation, which base can be adjusted. The calculation quantity of the two algorithms is analyzed respectively and compared with each other. The result shows the new algorithm's rapidity.
