(a) Traditional methods;
(b) Segmentation-based methods;
(c) Regression-based methods;
(d) Hybrid methods.
It is important to notice that: (1) "Hori" stands for horizontal scene text datasets. (2) "Quad" stands for arbitrary-quadrilateral-text datasets. (3) "Irreg" stands for irregular scence text datasets. (4) "Traditional method" stands for the methods that don't rely on deep learning.
