Abstract
It takes much more time for us to read the information of high resolution image. When the object section that we are interested in is high bright image elements in the image and has the line property, the best way to descript it is to use a line segment. The previous image compress technologies including nearest neighbor, bilinearity and bicubic, etc., are designed to adapt the general image and has the satisfaction effect in whole. But sometimes they compress a line to a dot-line. It brings trouble to read the real information of the image. In this paper, we present a new method - maximum extraction based on block segmentation to compress image and it keeps the line property well. Because the maximum extraction improve the average value of the extract image, it looks more bright than the original image, then we use grey transform to change the brightness of the image to make it close to the original image. Through many experiments, it is proved very effect to help us recognize the road and some other high bright objects with line property.
