Class TextDetectorCNN


  • public class TextDetectorCNN
    extends TextDetector
    TextDetectorCNN class provides the functionallity of text bounding box detection. This class is representing to find bounding boxes of text words given an input image. This class uses OpenCV dnn module to load pre-trained model described in CITE: LiaoSBWL17. The original repository with the modified SSD Caffe version: https://github.com/MhLiao/TextBoxes. Model can be downloaded from [DropBox](https://www.dropbox.com/s/g8pjzv2de9gty8g/TextBoxes_icdar13.caffemodel?dl=0). Modified .prototxt file with the model description can be found in opencv_contrib/modules/text/samples/textbox.prototxt.

        Description copied from class: TextDetector
        Method that provides a quick and simple interface to detect text inside an image
        Overrides:
        detect in class TextDetector
        Parameters:
        inputImage - an image expected to be a CV_U8C3 of any size
        Bbox - a vector of Rect that will store the detected word bounding box
        confidence - a vector of float that will be updated with the confidence the classifier has for the selected bounding box
