A successful approach for currency recognition depends upon feature extraction of that currency image. This paper represents the heuristic analysis of characters and digits of serial number of Indian currency notes to recognition of currency notes. To recognize a character from a given currency image, there is a need to extract feature descriptors of such image. As an extraction method significantly affects the quality of whole OCR process, it is very important to extract features, which will be invariant towards the various light conditions, used font type and deformations of characters caused by a skew of the image. Heuristic analysis of characters is done for this purpose to get the accurate features of characters before feature extraction in currency recognition.
