Provided methods

pub fn run_multiple(
    &mut self,
    image: &mut Mat,
    output_text: &mut String,
    component_rects: &mut Vector<Rect>,
    component_texts: &mut Vector<String>,
    component_confidences: &mut Vector<f32>,
    component_level: i32
) -> Result<()>[src]

Recognize text using Beam Search.

Takes image on input and returns recognized text in the output_text parameter. Optionally provides also the Rects for individual text elements found (e.g. words), and the list of those text elements with their confidence values.

Parameters

  • image: Input binary image CV_8UC1 with a single text line (or word).

  • output_text: Output text. Most likely character sequence found by the HMM decoder.

  • component_rects: If provided the method will output a list of Rects for the individual text elements found (e.g. words).

  • component_texts: If provided the method will output a list of text strings for the recognition of individual text elements found (e.g. words).

  • component_confidences: If provided the method will output a list of confidence values for the recognition of individual text elements found (e.g. words).

  • component_level: Only OCR_LEVEL_WORD is supported.
