Rotation invariant image recognition using hough transform and support vector machines
José Ruiz-Pinales, Juan Jorge Acosta-Reyes, René Jaime-Rivas, Adán Salazar-Garibay · 2006
The Hough transform is an information preservation transformation which converts rotations of the image into translations. For this reason, it constitutes an ideal candidate for adding rotation invariance to SVM based image recognition systems. Experiments performed on face recognition are presented. The problem of translation invariance is also dealt with.
