Configurable parameters:

(float) binaryThreshold - The threshold of the binary map. It is usually set to 0.3.
(float) polygonThreshold - The threshold of text polygons. It is usually set to 0.5, 0.6, and 0.7. Default is 0.5f
(double) unclipRatio - The unclip ratio of the detected text region, which determines the output size. It is usually set to 2.0.
(int) maxCandidates - The max number of the output results.
