Detailed Description

This class represents high-level API for segmentation models.

SegmentationModel allows to set params for preprocessing input image. SegmentationModel creates net from file with trained weights and config, sets preprocessing input, runs forward pass and returns the class prediction for each pixel.

Constructor & Destructor Documentation

◆ SegmentationModel() [1/2]

cv::dnn::SegmentationModel::SegmentationModel ( const String model,
const String config = "" 
)
Python:
cv.dnn_SegmentationModel(model[, config]) -> <dnn_SegmentationModel object>
cv.dnn_SegmentationModel(network) -> <dnn_SegmentationModel object>

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

Parameters
[in]modelBinary file contains trained weights.
[in]configText file contains network configuration.

◆ SegmentationModel() [2/2]

cv::dnn::SegmentationModel::SegmentationModel ( const Net network)
Python:
cv.dnn_SegmentationModel(model[, config]) -> <dnn_SegmentationModel object>
cv.dnn_SegmentationModel(network) -> <dnn_SegmentationModel object>

Create model from deep learning network.

Parameters
[in]networkNet object.

Member Function Documentation

◆ segment()

void cv::dnn::SegmentationModel::segment ( InputArray  frame,
OutputArray  mask 
)
Python:
cv.dnn_SegmentationModel.segment(frame[, mask]) -> mask

Given the input frame, create input blob, run net.

Parameters
[in]frameThe input image.
[out]maskAllocated class prediction for each pixel
