Struct opencv::dnn::TextDetectionModel_EAST

pub struct TextDetectionModel_EAST { /* private fields */ }

This class represents high-level API for text detection DL networks compatible with EAST model.

Configurable parameters:

• (float) confThreshold - used to filter boxes by confidences, default: 0.5f
• (float) nmsThreshold - used in non maximum suppression, default: 0.0f

Implementations

impl TextDetectionModel_EAST

pub fn default() -> Result<TextDetectionModel_EAST>

pub fn new(network: &impl NetTraitConst) -> Result<TextDetectionModel_EAST>

Create text detection algorithm from deep learning network

• config: Text file contains network configuration.

C++ default parameters

• config: “”

pub fn from_file_def(model: &str) -> Result<TextDetectionModel_EAST>

Create text detection model from network represented in one of the supported formats. An order of @p model and @p config arguments does not matter.

Parameters
