Currency Recognition Using Mathematical Morphology and Neural Networks

As m orphological im age analysis tools granulom etrics are particularly useful for estim ating objectsizes in binary and grayscale im ages,or characterizing textures based on their pattern spectra(i.e., granulom etric curves).In this paper,the pattern spectrum of texture based on grayscale granulom etries w hich use opening operators w ith line structures was intruduced.The pattern spectrum w as used as the feature of texture and the tw o hidden layer neural networks w ere used for recognition.At the end, experim entalresults were shown.
