t()

Type that represents an Text.TextDetector struct.

Method that provides a quick and simple interface to detect text inside an image

@type t() :: %Evision.Text.TextDetector{ref: reference()}

Type that represents an Text.TextDetector struct.

@spec detect(Keyword.t()) :: any() | {:error, String.t()}

@spec detect(t(), Evision.Mat.maybe_mat_in()) ::
  {[{number(), number(), number(), number()}], [number()]}
  | {:error, String.t()}

Method that provides a quick and simple interface to detect text inside an image

bbox: [Rect].
a vector of Rect that will store the detected word bounding box
confidence: [float].
a vector of float that will be updated with the confidence the classifier has for the selected bounding box

Python prototype (for reference only):

detect(inputImage) -> Bbox, confidence
