摘要
Abstract
The log‐polar transformation blurred images ,details surrounding area loss serious and large amount of data , so the non‐uniform rectangular sampling algorithm is proposed .The computing data quantities of LPT ,variable parameter LPT algorithm were compared ,it can be discovered when image size is 256 × 256 ,non‐uniform rectangular sampling method the pixel data only 5066 .The calculating quantity of rectangular algorithm is the least .关键词
