Abstract: Detection and extraction of facial spots, wrinkles and pores for diagnosis of dermatosis, decision of efficacy of cosmetic and evaluation of skin are necessary. It selects a rectangular area in the facial skin image, diagnoses this area by using a filter bank which includes a wavelet homomorphic filter for detecting the spots and a ε-filter bank for detecting the wrinkles and pores. It extracts them by combining their characteristics with some morphological algorithms in image processing. It validates the accuracy of the method on the analysis of experimental result.

Key words: image diagnosis, wavelet homomorphic filtering, ε-filer bank
