\brief This class represents high-level API for text detection DL networks compatible with DB model. Related publications: \cite liao2020real Paper: https://arxiv.org/abs/1911.08947 For more information about the hyper-parameters setting, please refer to https://github.com/MhLiao/DB 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.
