Abstract

Disclosed in an embodiment of the present invention are a thumbnail generating method and system, the method comprising: obtaining the sizes of an original picture and a target thumbnail; calculating the product of a preset coefficient and the size of the target thumbnail to obtain a thumbnail size corresponding to the original picture, the preset coefficient being greater than 1; zooming out the original picture according to the thumbnail size corresponding to the original picture to obtain an intermediate result picture; determining a weight value distribution map of the pixels in the intermediate result picture; and clipping the intermediate result picture according to the weight value distribution map of the pixels and the size of the target thumbnail so as to obtain a thumbnail comprising an area of interest to human eyes. The embodiment of the present invention ensures that an area of interest to human eyes in a picture is retained in a thumbnail, thus improving thumbnail effect.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and system for generating a thumbnail. Background technique [0002] When images are displayed on electronic devices such as smart phones and digital cameras, in order to shorten the loading time when displaying images and improve the user's browsing experience, thumbnails of the images are displayed in most cases. Among them, a traditional method for generating a thumbnail is: first scaling the picture to a certain size, and then cutting the scaled picture to generate a thumbnail. Among them, the method of cropping the zoomed picture is usually to use the center crop or the center fixed upper crop, whichever method is a one-size-fits-all method, and there is no guarantee that the thumbnail will retain the image that is of interest to the human eye. area. Contents of the invention [0003] Embodiments of the present invention provide a method and system for gene...
