We create a horizontal shaped kernel using cv2.getStructuringElement() then dilate using cv2.dilate() to combine individual letters into a single contour. Remove non-text contours. We find contours with cv2.findContours() and filter using aspect ratio to remove non-text characters. Web- "CTC-greedy", the output of the text recognition model should be a probability matrix. The shape should be `(T, B, Dim)`, where - `T` is the sequence length - `B` is the batch size (only support `B=1` in inference) - and `Dim` is the length of vocabulary +1('Blank' of CTC is at the index=0 of Dim).
