Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] The inventor noticed during the invention that:

[0026] In the existing thumbnail generation scheme, the middle part of the picture is intercepted or the entire picture is reduced to be used as a thumbnail for browsing.

[0027] Because in the process of generating thumbnails, only the middle part of the picture is cut mechanically or the...

Abstract

The embodiments of the invention provide a reduced graph generation method and device. The method comprises the following steps: analyzing a picture according to a preset rule, and determining a significance value of each pixel point; performing area segmentation on the picture; determining the significance value of each pixel point of each area; according to the significance value, selecting an area where a reduced graph is generated; and generating the reduced graph on the basis of the area. By use of the scheme provided by the embodiments of the invention, the generated reduced graph can represent an original picture most, can be well directed to and represent the original picture, and improves the efficiency and experience of a user in checking a graph database.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to a method and device for generating a thumbnail. Background technique [0002] Thumbnails play an important role in the browsing process of photo albums. Batch browsing methods are provided. The improvement of thumbnail quality is an important requirement in the gallery browsing process. In the existing thumbnail generation scheme, it is to intercept the middle part of the picture or Zoom out the image as a whole and use it as a thumbnail for browsing. [0003] The disadvantage of the prior art is that the generated thumbnail cannot always enable the user to know the picture pointed to by the thumbnail through the thumbnail, that is, the thumbnail generated from the original picture cannot clearly point to and represent the original picture. Contents of the invention [0004] Embodiments of the present invention provide a method and device fo...
