Struct opencv::dnn::TextDetectionModel_EAST

pub struct TextDetectionModel_EAST { /* fields omitted */ }

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: &Net) -> Result<TextDetectionModel_EAST>
