Embodiment Construction

[0045] A method for classifying image textures based on jump subdivision local patterns, comprising the following steps:

[0046] Step 1: Jumping local differential counting features (JLDCP), including second-order differential counting features (SDCP) and diagonal differential counting features (DDCP):

[0047] Calculation of second-order differential counting features (SDCP): It mainly extracts features in the spatial range of the local area, and realizes the differential relationship between the neighboring pixels of the central pixel in the local area. In theory, enough differential operations can extract the unstable information in the image, but the more times the better, the differential is the refined extraction of information, and some features will be lost, so it should be used appropriately in actual use. First, first specify the position of a neighbor pixel, then perform a difference operation with the previous pixel point, then perform a difference operation betwe...

Abstract

An image texture classification method based on jump subdivision local pattern includes:firstly, skipping local difference counting feature (JLDCP) information is extracted from the second-order difference counting feature and diagonal difference counting feature, then the subdivision complete local binary feature (RCLBP) is extracted from the symbol information and size information of the subdivision complete local binary feature, finally, the texture descriptors (JRLP) of skipping and subdivision local patterns are obtained by connecting the skipping local difference counting feature (JLDCP)and the subdivision complete local binary feature (RCLBP). The invention has the beneficial effects that the invention has robustness to image noise, rotation, scale and illumination change and the like.

Description

technical field [0001] The invention relates to the technical fields of computer vision and pattern recognition, in particular to an image texture classification method based on jumping and subdividing local patterns. Background technique [0002] Texture is a ubiquitous and indescribable visual feature, which is the repetition of basic units according to certain rules. People have the following consensus on its attributes, periodicity, directionality, regionality and scale. People generally divide textures into three categories, natural textures, artificial textures, and mixed textures. The texture classification process can generally be briefly summarized as follows: First, all texture images must be read in. Secondly, according to the construction method of the texture feature, the feature of each texture image is constructed. Then divide the picture features into training set and test set, and finally use a classifier to classify the pictures in the test set according...
