Abstract: Fake currency notes are so perfect nowadays that it is very tough to differentiate them from original currency notes. Due to technological advancements, it has become very easy for counterfeiter’s to imitate all the characteristics of the original currency except the illumination or glow that occurs when the currency notes are induced to UV radiation. The proposed approach is based on this selective feature of color illumination which can be identified when the captured image is converted into HSV color space. Histogram equalization is done in HSV color space which collectively performs noise reduction, filtering and sharpening to enhance image quality for effective use in applications. The original currency will have high intensity color values compared to the fake currency that can be verified by using the thresholding technique. Thus, the proposed method is very simple, efficient and time saving.
