Abstract

The invention discloses an image texture retrieval method, and relates to the technical field of image processing in computer vision, and the method comprises the steps of converting a to-be-retrieved target image from a spatial domain to a frequency domain; performing convolution operation on the transformed target image and a Log-Gabor filter; performing inverse Fourier transform on a convolution operation result to obtain a Log-Gabor response image; obtaining a maximum edge position octal mode LMEPOP feature vector of the Log-Gabor response image through a local texture feature LBP; retrieving similar images from an image library according to the extracted feature vectors, wherein the feature vectors of the images are stored in the image library. The problems that in the prior art, due to the fact that direct-current components exist, retrieval accuracy is low, and consumed time is long are solved, and the effects of improving retrieval accuracy and shortening retrieval consumed time are achieved.

Description

technical field [0001] The invention relates to an image texture retrieval method, which belongs to the technical field of image processing in computer vision. Background technique [0002] Images play a vital role in almost every aspect of human life, such as pattern recognition, artificial intelligence, crime prevention, surveillance, news, medicine, etc. When maintaining a large collection of images, it is necessary to search and retrieve images based on user requests . At the same time, many techniques have been proposed to browse and search images in huge image databases. Among them, the content-based image retrieval system has relatively low requirements on people, so it is very popular. However, content-based image retrieval searches the image database through similar types of images and according to user needs. It analyzes the content of the image, such as color, texture, shape, etc., rather than any information about the following such as text annotations, Images...
