摘　　要：图像转置算法是数字图像处理的重要领域之一,本文针对图像转置的前向映射方法和后向映射方法进行研究,并针对两个算法的处理时间,处理图像清晰度进行分析,然后对后向映射处理时间问题提出基于双线性插值的后向映射方法,改进结果较传统算法而言,转置全过程所花费平均时间节省2.16倍。Image transposition algorithm is one of the important areas of digital image processing.This paper studies the forward mapping method and backward mapping method of image transposition,and analyzes the processing time and image sharpness of the two algorithms.Then,a backward mapping method based on bilinear interpolation is proposed for the processing time of back⁃ward mapping.Compared with the traditional algorithm,the average time spent transposing the entire process is saved 2.16 times.
