From: BCSR: toward arbitrarily oriented text image super-resolution via adaptive Bezier curve network
Visual comparison of rectified images under different annotations. a employs polyline annotations, using an STN-based method to rectify the original ground truth to an approximate rectangular text. b uses Bezier annotation, the red points are control points, and the red dashed lines form a control polygon for each curve boundary. We utilize the Bezier curve and BezierAlign to revise the results. The picture below is the outcome of warping
