Embodiment Construction

[0025] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The embodiments of the present application can be applied to various image content retrieval fields such as computer vision and graph databases. For example, based on road image retrieval, it can quickly locate the location, and based on commodity image retrieval, it can quickly retrieve commodity objects, etc.

[0027] refer to figure 1 A schematic diagram of an image processing example is shown.

[0028] Step 102, using a source image and a similar image in a similar image set of the source image to form at least one image pair, the similar image set including at least one similar image.

[0029] Content-based image retrieval can be divided into two stages, one stage is the rough sorting stage...

Abstract

The embodiment of the invention provides an image processing method and device, an image retrieval method and device, equipment and a storage medium, and aims to improve the image retrieval efficiency. The method comprises the steps that a source image and similar images in a similar image set of the source image are adopted to form at least one image pair, and the similar image set comprises at least one similar image; performing feature matching on the source image and the similar image in the image pair, and determining a corresponding first feature subset and a corresponding second feature subset; determining the similarity between the first feature subset and the second feature subset based on the topological structure information of the feature points; and determining a similar image screening result in the similar image set according to the similarity. The calculation amount is low, the resource consumption is low, and the retrieval efficiency of similar images can be improved.

Description

technical field [0001] The present application relates to the field of communication technology, in particular to an image processing method and device, an image retrieval method and device, a product object search method, a road search method, an electronic device and a storage medium. Background technique [0002] Content-Based Image Retrieval (CBIR) is a scheme for searching images based on the content of images. [0003] In one example, a user can input an image, and other images with the same or similar content can be searched based on the CBIR technology. In the current CBIR technology, it is usually to determine the feature points in the two images, then estimate the transformation matrix based on the feature points, and then match the changes of the feature points based on the transformation matrix, from the set of feature points determined, and then transform the matrix again, repeat the above Process until the convergence or error requirements are determined to de...
