Method Detail

detect

public void detect(@ByVal
                   Mat frame,
                   @ByRef
                   PointVectorVector detections,
                   @StdVector
                   FloatPointer confidences)

\brief Performs detection Given the input \p frame, prepare network input, run network inference, post-process network output and return result detections. Each result is quadrangle's 4 points in this order: - bottom-left - top-left - top-right - bottom-right Use cv::getPerspectiveTransform function to retrive image region without perspective transformations. \note If DL model doesn't support that kind of output then result may be derived from detectTextRectangles() output.

Parameters:

frame - [in] The input image

detections - [out] array with detections' quadrangles (4 points per result)

confidences - [out] array with detection confidences
