Abstract

The invention discloses a method for generating an image retrieval database, an image retrieval method, a corresponding image retrieval database generator, an image retrieval device, and an image retrieval system; when generating the database, classify and reduce the dimensionality of sample image feature description information, for Each feature point forms a label data; classify and store the sample image content data and label data in the database; in image retrieval, use a similar method to process the target image to be retrieved to form multiple labels for each feature point; When matching, the label of the target image is traversed and matched with all the labels in the corresponding classification index in the database, and the matching score between the target image and each sample image in the database is calculated. The invention realizes the compression of the description content, and can effectively improve the data transmission efficiency. In addition, classifying and storing sample image content data and label data can effectively reduce the waiting time for image retrieval and make it possible to realize real-time retrieval in large databases.

Description

technical field [0001] The present invention relates to the technical field of content-based image retrieval, in particular to an image retrieval system and related methods and devices. Background technique [0002] In the field of computer vision, features in an image can be characterized by identifying and describing one or more key points. The key points can be described by various description contents, for example, the description content of the key points can be expressed by the visual features of the image content (shape, color, texture, rotation and other image characteristics). In image recognition, the features in the target image are matched with the features in the sample image database. When the calculation speed of the key point detection of the object and the size of the image feature database are fixed, the time consumption mainly depends on the transmission and storage of image features. , so the construction complexity and dimensionality of the key point de...
