| 摘 要： | 纸币清分机采集图像是在纸币快速进纸过程的情况下实现，不可避免的会发生倾斜，这为后续的图像分割和识别带来了困难。针对图像中纸币边缘检测结果通常断裂为若干直线段的现象，本文提出了一种基于Hough变换的改进倾斜矫正算法，能够较准确地检测到图像的倾斜角度，从而实现纸币图像的倾斜矫正。

| Abstract: | 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, we proposed an improved banknote Tilt-Correction method based on Hough-Transform, which can detect the tilt angle accurately. |
