Application of linear regression and Hough transform in calculating declining angle of image

ZHAO Nan_nan~(1,2),OUYANG Xin_yu~1,WU Qing_hong~1(1.School of Electronic and Informaiton EngineeringAnshan University of Science and Technology,Anshan 114044,China;2.Institute of Artifitical Intelligence and Robotics,Northeast University,Shenyang 110006,China)  
Before rectangle image is recognized,we usually have to rectify the declining angle of the image.In this paper,two methods are given,which are linear regression method and Hough transform method.The paper will introduce their principles,algorithm,realization process,simulaiton results,advantages and disadvantages.The two methods have been used in engineering practice,they both have good effects.
