Thumbnail-based image sharing method and terminal

Abstract

Embodiments of the invention provide a thumbnail-based image display method and a terminal. The method comprises the steps of displaying a thumbnail on a screen; performing feature extraction on the thumbnail to obtain a feature factor of the thumbnail; if the feature factor of the thumbnail is matched with that in a preset feature factor index library, displaying prompt information on the screen, wherein the feature factor index library represents a corresponding relationship between the feature factor and an image storage address, and the prompt information represents that an original image matched with the thumbnail exists; obtaining an original image acquisition request; and displaying the original image on the screen according to the original image acquisition request. According to the image display method and the terminal provided by the embodiments of the invention, feature indexes are created for all pictures applied to a memory and a cache as well as a picture library, and a high-resolution original picture is found by utilizing the feature factor of the thumbnail, so that high-definition image sharing among different applications is realized.

Description

technical field [0001] The invention relates to the field of media image processing, in particular to a method and terminal for image sharing between different application programs based on thumbnails. Background technique [0002] Image retrieval refers to the retrieval of relevant graphic and image data by searching for image text or visual features. Image retrieval can be performed in the following ways: image retrieval by entering keywords similar to the image name or content; image retrieval by voice recognition; image retrieval by uploading images or hyperlinks pointing to images. [0003] In image retrieval technology, the server or client that performs the actual retrieval can create index information from images, for example, through image analysis and recognition, adding annotations to images, etc., and then build an index library based on the index information. [0004] In image retrieval technology, the main retrieval methods are as follows: [0005] Based on i...
