Abstrakt: The cosmetic defects on lenses are a problem in the optical industry. They are an important source of economic looses due to rework. A method to detect the scratch defect is proposed. We will show that using the wavelet approach yields in a high performance method detecting these defects, making more reliable the inspection stage. [ABSTRACT FROM AUTHOR]
