Abstract

The invention discloses a texture feature extraction method. The texture feature extraction method includes the following steps: segmenting an image to be processed through a plurality of preset segmentation methods, wherein any sub-image obtained by each segmentation method and other The sub-images obtained by the segmentation methods are all different; the sub-images obtained by segmentation according to the same segmentation method are respectively combined into a first combined image, and each of the first combined images is combined into a second combined image; The image is subjected to a local binary mode LBP operation, and the obtained LBP feature is used as the texture feature of the image to be processed. The invention also discloses a texture feature extraction device. The invention can accurately extract the texture feature of the image.

Description

[0001] technology neighborhood [0002] The invention relates to the field of image processing, in particular to a texture feature extraction method and device. Background technique [0003] Face recognition is a biometric technology for identification based on the texture features of the face, usually also called portrait recognition or facial recognition. At present, in the face recognition neighborhood, the LBP (Local Binary Patterns, local binary pattern) feature of the image is usually extracted as the texture feature of the image. When extracting, the horizontal and vertical coordinates of the image are firstly divided equally and then the LBP operation is performed. The LBP features of each sub-image are concatenated as the LBP features of the original image. However, when the image is segmented, the texture features of the image segmentation line will be filtered out, resulting in inaccurate texture feature extraction. Contents of the invention [0004] The main pu...
