Problems solved by technology

However, in the prior art, a relatively mature texture feature extraction scheme has not been proposed. The selection of texture features is relatively arbitrary and cannot be accurately positioned. The texture feature extraction method is also complicated and needs to be improved.

Embodiment Construction

[0028] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] Embodiment 1 of the present invention provides a method for extracting image texture features, see figure 1 , the method includes:

[0030] 11: Obtain the grayscale image of the original image;

[0031] 12: Divide the grayscale image into a plurality of image blocks, and calculate the grayscale co-occurrence matrix of each image block;

[0032] 13: Use angular second-order distance, contrast, entropy and related features as selected texture features;

[0033] 14: Calculate the te...

Abstract

The invention discloses a method and device for extracting image texture features, which can accurately and quickly extract the texture features of the original image and improve the robustness of the texture features. The method for extracting image texture features provided by the embodiments of the present invention includes: acquiring the grayscale image of the original image; dividing the grayscale image into a plurality of image blocks, and calculating the grayscale co-occurrence matrix of each image block; , contrast, entropy and related features are used as the selected texture features, and the texture features of each image block are calculated according to each gray level co-occurrence matrix; according to the texture features of each image block, the corresponding texture features of the original image are obtained.

Description

technical field [0001] The invention relates to the technical field of image and graphics processing, in particular to a method and device for extracting image texture features. Background technique [0002] As the scale of the Internet becomes larger and larger, texts, pictures, and multimedia information are increasingly abundant. In order to find useful information users need to search huge amounts of data. During the search process, accurate features must be extracted in order to locate accurately. Texture features are important features for images, and texture features, color and shape features are called the three major features of images. [0003] At present, there are mainly three types of methods for extracting texture features. The first type is based on statistics, and the main method is to use gray-level co-occurrence matrix. The second category is the structure-based method, which is generally only used when the texture primitive is large enough to be divided...
