ROTATION INVARIANT IMAGE REGISTRATION WITH RADON TRANSFORM
Shehan Fernando, Thilan Cooray, Sri Lanka · 2011
This paper presents a methodology for rotation invariant image registration technique using Radon transform. Image based operations such as desktop scanning is performed in a domain which is vulnerable mainly to geometric attacks such as rotation. For this task we have employed radon transformation to correct any image rotation which can be either clockwise or counter clockwise in image scanning. Moreover, this method utilizes image processing techniques such Canny edge detection and morphological operations on binary images, such as thickening. The experimental results prove the effectiveness of the algorithm for correcting the amount of rotation.
