Image processing method and device

Abstract

The invention discloses a picture processing method and an apparatus and belongs to the picture processing field. The method comprises the following steps of according to a pixel point in a target picture to be processed, acquiring a plurality of significant rectangles from the target picture; based on areas of the plurality of outstanding rectangles, a significant mean value of the plurality of significant rectangles and center distances of the plurality of significant rectangles, calculating an anchor point coordinate of the target picture, wherein the center distance of each significant rectangle is a distance between a center point of each significant rectangle and a center point of the target picture; based on the anchor point coordinate of the target picture, moving the target picture so that an anchor point of the target picture is superposed with a center point of a cutting frame; and based on the position of the cutting frame, carrying out cutting processing on the target picture. By using the method and the apparatus of the invention, times for a user to manually adjust the target picture are reduced and picture cutting processing efficiency is increased.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing method and device. Background technique [0002] With the rapid development of terminal technology, the picture processing function of the terminal is increasingly powerful. Not only can the picture beautification function be provided on the terminal, but also the function of cutting the picture can be provided. For example, when the user sets the mobile phone wallpaper picture or changes the avatar picture, the size of the area to be filled is fixed. For example, for the wallpaper picture, the area to be filled may be the same size as the terminal display screen, while for the avatar, The area to be filled may be small, and if the size of the picture selected by the user is larger than the size of the area to be filled, the picture needs to be cropped. [0003] At present, the image processing process can specifically be as follows: after the user se...

Problems solved by technology

[0004] The salient area of ​​the picture is generally the area that can most arouse the user's interest and express the content of the picture. When the salient area of ​​the target picture is not in the center of the target picture, the above method cannot accurately place the salient area of ​​the target picture in the center of the target picture. The center position of the cropping frame needs to be adjusted manually by the user repeatedly. The operation is more complicated, which reduces the efficiency of image cropping
