Extraction of Serial Number on Currency Notes Using Labview

J Bhaskara Rao, A SivaKumar

Currency has great importance in day to day life and therefore the currency recognition is a great area of interest for researchers. Image processing is the most popular and effective method of currency recognition. Image processing based currency recognition technique consists of few basic steps like image acquisition, its pre-processing and finally recognition of the currency. 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.
