Image Denoising and Quality Inspection of Micro Components Using Perona-Malik Diffusion☆

Abstract The production of micro components has received much attention on the last years and has recently become one of the crucial tasks of product and processes oriented research. During the production of very small parts, many unanticipated manufacturing errors such as cracks, wrinkles and form deviations may occur. In order to minimize these defects (flaws) and simultaneously achieve an economically efficient production of micro parts the suitable methods for quality inspection are required. This paper focuses micro- components manufactured by means of micro-cold forming techniques. The new methods for error detection in micro components are proposed. The quality of presented approach will be demonstrated in numerical examples.
