Medical gauze defect detection method

The invention discloses a medical gauze defect detection method, and relates to the technical field of image processing. Comprising the following steps: acquiring a spectrogram of a grayscale image of medical gauze; obtaining a change range of a template size of the gray level image; segmenting the grayscale image into a plurality of sub-images with the same size; obtaining a regular direction degree of each sub-image; obtaining the structural stability of each sub-image; obtaining the size of a sub-template of each sub-image in the grayscale image; selecting a sub-template for each sub-image according to the size of the sub-template of each sub-image; obtaining the matching degree of the sub-images and the sub-templates of the sub-images, and obtaining a defect area of each sub-image according to the matching degree; according to the invention, the technical problems of missing detection and detection and low detection precision and detection efficiency during medical gauze defect detection in the prior art
