Problems solved by technology

However, due to the overall layout and aesthetics of the thumbnails in the album, the square centered cropping method is adopted, so that the thumbnails we obtain currently cannot show the main area of ​​the user on most of the images, resulting in the user being unable to understand the whole picture through the thumbnail The information of the picture cannot play the real role of the thumbnail

Abstract

Disclosed is a method for acquiring a thumbnail based on image saliency detection. The method comprises: conducting image saliency detection on an image to be processed to acquire a saliency region of the image; calculating the largest rectangular region containing the saliency region; and finally, according to the largest rectangular region, conducting image clipping, so as to obtain a thumbnail of the image to be processed. Therefore, thumbnails of a large number of images can be acquired quickly and effectively, so that the acquired thumbnail can reflect a main region of the image and fully display information about the entire image, thereby facilitating a user in browsing quickly.

Description

technical field [0001] The invention relates to an image processing method, in particular to a method for acquiring thumbnails based on image saliency detection. Background technique [0002] At present, in order to make the photos look better, we often use the "golden section" in the composition. It is a phenomenon that exists widely in nature. It makes people feel that the picture is harmonious and full of beauty. The "Golden Section" is also called the "Rule of Thirds". The "Rule of Thirds" is to divide the entire picture into three equal parts with two straight lines in the horizontal and vertical directions. We place the subject on any straight line. Or the intersection of straight lines is more in line with human visual habits. When shooting, you can directly call up the camera's "well" auxiliary line, and place the subject on the four intersection points, so that the picture will come alive immediately. However, due to the overall layout and aesthetics of the thumb...
