基于seam carving技术的图像非等比缩放

数字图像的缩放分全等比例缩放和非等比例缩放。本文主要研究图像非等比例的缩放。传统的图像缩放技术采用插值算法,但是这种算法在缩放时经常会出现马赛克或者图像内容丢失现象。本文研究的seam carving技术首先对图像进行能量描述,使图像中不同内容的景物具有不同的能量,然后找到图像水平和垂直方向的最低能量线,对其进行删除或插入操作,就可以在图像缩放中最大限度地保留图像的重要内容。该方法应用在视频图像4:3到16:9的转换上可以取得很好的效果。通过Matlab实验结果表明,本文的方法在图像进行非等比例缩放时,具有很好的抗畸变性能。

Non-proportional Resizing of Image Based on Seam Carving Technique

There are two types of digital image scaling,which are proportional scaling and non-proportional scaling.This paper described non-proportional scaling.Conventional image scaling technique uses interpolation algorithm.But this algorithm often appeared the phenomenon of mosaic and the loss of image content.This paper described the energy of the image in order to endue the different elements of the image with different energy.Then find the lowest energy line of horizontal and vertical direction and delete or i...
