Embodiment Construction

[0045] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0046] This solution uses the solid-state hard drive as the picture database, and realizes the picture library generation and picture query functions in its main control FPGA chip, that is, realizes the construction of the picture library and the similarity measurement of pictures in the solid-state hard drive main control FPGA chip. In this way, when querying pictures, after the feature information of the picture is extracted by the main control FPGA chip of the solid-state hard disk, the similarity comparison with the pre-classified features in the picture database is performed to sort the matching degree of the pictures, so as to achieve efficient and high reliability. Image search function.

Abstract

The invention discloses an image retrieval system and an image retrieval method based on FPGA. According to the image retrieval system, a solid state disk is used as an image database, and an image library generating module and an image query module are achieved in the master control FPGA chip of the image retrieval system. The method comprises the steps of inputting an image to be queried by a user, and after extracting the feature information of the image, sorting images according to the matching degrees through performing similarity comparison between the feature information with presort feature in the image library. The innovation of the image retrieval system and the image retrieval method provided by the invention lies in that the solid state disk is used for achieving the establishment of the image library and the measurement of the image similarity, the computational burden of the CPU is reduced, the retrieval process is accelerated, and the timeliness of retrieving in mass image data is improved.

Description

technical field [0001] The invention relates to the technical field of image retrieval, in particular to FPGA image retrieval technology. Background technique [0002] Content-based image retrieval is carried out according to the visual characteristics of the image. Its main idea is to establish the feature vector of the image according to the information contained in the image, such as color, texture, shape, and object spatial relationship. Similarity calculations are performed on the features of the dimension and the output is sorted according to the retrieval results. By analyzing the content of the image, such as the color, texture, shape, etc. of the image, a feature index is established and stored in the image feature library. [0003] In this way, the user only needs to provide the image to be queried when searching, and the system first extracts the feature vector of the image, and then compares it with the feature vector of the image in the image database to find s...
