A textural analysis by mathematical morphology transformations: structural opening and top-hat

This paper presents a new method of texture characterization, recognition and defect detection in textures, based on mathematical morphology transformations: structural opening and top-hat. The structural opening and its properties of invariance allow the extraction of primitive patterns from a texture, some kind of “textons” which entirely characterize it. As a result, defect detection can be performed by a top-hat transformation for a similar textural set with defects, and texture recognition can be led by a reference set
