Abstract

The invention provides an image processing device and method. The image processing device comprises an extraction unit, a feature point matching unit and a group generation unit, wherein the extraction unit is used for extracting feature points representing local features of ungrouped images; the feature point matching unit is used for matching the feature points of input ungrouped images with the feature points of the other ungrouped images and determining the images, matched with the input ungrouped images, among the other ungrouped images to serve as a matching image set; and the group generation unit is used for generating new image groups based on the matching image set under the conditions that the matching quantity of the input ungrouped images and the other ungrouped images is greater than or equal to a first predetermined quantity and the quantity of grouped feature points among the matching feature points is greater than or equal to a threshold quantity, wherein the grouped feature points are located in an image identification region. According to the image processing device and method in the embodiment, the images can be grouped automatically and accurately.

Description

technical field [0001] The present invention relates to an image processing device and method, and more particularly, to a device and method for automatically grouping images. Background technique [0002] With the popularization of smart mobile terminals, users are becoming more and more accustomed to recording various information by taking pictures of mobile terminals. For example, information recording is performed by photographing newspapers, periodicals, water bills, and electricity bills, etc., and users can obtain desired information by retrieving these images later. This method is very convenient for users. [0003] By grouping images recorded with various information, it is possible to greatly improve the efficiency for users to acquire desired information by retrieving images. However, compared with text information, image information is very difficult for computers to automatically process and classify. Contents of the invention [0004] In view of the above-...
