An Improved Method for Banknote Tilt-correction Based on Hough-transform
AI Zhao-xia · Science Technology and Engineering · 2011
It was inevitable to cause skew in the process of banknote quick feeding in image collection,which may make it difficult for the following-up image segmentation and recognition.For the traditional edge detection method,the detected image may break into several straight segments.To solve this problem,an improved banknote tilt-correction method based on Hough-transform is proposed,which can detect the tilt angle accurately.
