Abstract: Estimating and rectifying the orientation angle of any image is a prettychallenging task. Initial work used the hand engineering features for thispurpose, where after the invention of deep learning using convolution-basedneural network showed significant improvement in this problem. However, thispaper shows that the combination of CNN and a custom loss function speciallydesigned for angles lead to a state-of-the-art results. This includes theestimation of the orientation angle of any image or document at any degree (0to 360 degree),
