Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] figure 1 is a flowchart of a texture image retrieval method provided in an embodiment of the present invention, see figure 1 , the method includes:

[0042] 101: Process the input texture image according to the rotation invariant local binary pattern algorithm, and acquire the structural pattern image of the input texture image;

[0043] Among them, the input texture images are all single-channel grayscale images. For multi-channel images, such as RGB, CMY, YIQ, etc., it is necessary to convert the multi-channel image into a single-channel grayscale image, or convert each of the multi-channel images channel image alone as the input texture image.

[0044] Among them, the basic principle of the rotation-invariant local binary ...

Abstract

The invention discloses a texture image retrieval method and a texture image retrieval device and belongs to the field of digital image processing. The method comprises the following steps: processing an input texture image according to a rotation invariant local binary pattern algorithm, so as to acquire a structural pattern image of the input texture image; performing feature extraction on the structural pattern image of the input texture image according to a pulse coupling neural network model, so as to obtain a structural feature sequence of the input texture image; acquiring the retrieved texture image according to the structural feature sequence of the input texture image and a structural feature sequence of each image in a texture image database. The feature extraction is performed by using the structural pattern image, the photoperiod sensitivity is effectively overcome, the extracted structural feature sequence has characteristics of illumination, transition, rotation, zoom and affine invariant, and thus image retrieval is well realized.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to a texture image retrieval method and device. Background technique [0002] With the rapid development of computer network technology, various texture image databases are growing rapidly. How to quickly and effectively obtain the required images from these texture image databases is an important research topic in the field of texture image retrieval. [0003] In the prior art, the pulse-coupled neural network model is used to extract the image features of the retrieved texture image, and the similarity measurement is performed between the extracted image features and the image features of the image in the texture image database, and the same texture image is obtained to realize the texture image. search. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] In the prior art,...
