Also the code I gave above (https://github.com/clovaai/CRAFT-pytorch/issues/3#issuecomment-505903264) breaks down if the character quadrilateral is not valid. To check you can use - from shapely.geometry import Polygon Polygon(bbox.reshape([4, 2]).astype(np.int32)).is_valid: If this...

You are assuming that the character bbox would always be horizontal which is not the case. Also, if you create the Gaussian heatmap everytime for a new character, it would...

@hanish3464 You could try this explanation of the perspective transform. https://www.pyimagesearch.com/2014/08/25/4-point-opencv-getperspective-transform-example/ They are trying to bring a skewed image back to horizontal rectangle using four_point_transform, while I am doing the...

Quadrilateral instead of rectangle, not polygon

I think the Gaussian heat map you are using has a very small standard deviation because of which the characters are not getting connected by the affinity. Try increasing the...

Another approach which works is to first train the model on a clean dataset and once the model is trained, freeze the model parameters and add two enhancement blocks to...
