Texture defect detection recognizes scratches, cracks, stains, and other defects that may vary in size and shape on textured surfaces. Use texture defect detection when traditional machine vision techniques such as dynamic thresholding and edge detection are not adequate to find the defects on the parts being inspected. Applications include the automated inspection of materials such as ceramic tiles, textiles, lumber, paper, plastic surfaces and glass, which are often characterized by irregular texture patterns.

The following figure shows examples of texture defects that traditional machine vision techniques may not adequately detect.
