Embodiment

[0050] The embodiment of the present invention provides image feature extraction and classification. The image feature extraction and classification method extracts the features from the acquired grayscale images of the warp knitted fabrics, and classifies them according to the extracted features. Through the method of image feature extraction and classification, fast and effective feature extraction of warp-knitted fabric image flaws and classification and identification of warp-knitted fabric flaws, the efficiency and accuracy of recognition are improved.

[0051] see figure 1 , by carrying out the method for feature extraction to the gray-scale image of the warp-knitted fabric that obtains, comprise the following steps:

[0052] S110: Acquiring a grayscale image of the warp-knitted fabric;

[0053] Specifically, the grayscale image of the warp-knitted fabric is obtained, and the grayscale image is divided into images with a size of 64*64 pixels.

[0054] S120: Perform me...

Description

technical field [0001] The invention relates to the fields of image processing, analysis and machine vision, in particular to a method and device for image feature extraction and classification. Background technique [0002] Current textiles have become an indispensable item in people's daily life, and most of them are produced automatically by warp knitting machines. Defects in warp knitted fabrics refer to production defects such as warp breaks, weft breaks, holes, and skipped stitches that occur during the production process of warp knitting machines. Such defects will affect the appearance of the finished product and cause economic losses. In order to improve consumer experience and reduce losses, it is necessary to monitor the above-mentioned defects in real time during the production process of warp knitting machines. Maintenance provides data support. The traditional detection method adopts the method of manual line inspection to observe whether the warp knitted fab...
