I am working on Autoamted Handwritten Digit Recognition with deep learning algorithm. Since the handwritten digits have a lot of variation, in terms of the slanted angles, so I would like to look for the potential solutions for digit slant detectiona and slant correction.
I have tried Hough Transform, however, it requires edges as reference and digit doesn't have a proper edge.
The example of slanted digit is shown in below:
I would like to correct its orientation so that my NN can recognize it accurately.
Thank You :D
