In this Currency detector for visually impaired project is especially useful for those people who have visual impairments. Visually impaired are those who have difficulty in vision or complete vision loss, which causes them trouble in recognizing the paper currencies. This application is a way out for them, as it will help to find out the value of currency. One of the most important problems facing visual impaired people is money recognition especially for paper currency.

Our proposed system is based on simple image processing utilities that insure performing the process as fast and robust as possible. The basic techniques utilized in our proposed system include image foreground segmentation, histogram enhancement, and region of interest (ROI) extraction and finally template matching based on the cross-correlation between the captured image and our data set.
