Detailed Description

Generate an ecvl::Dataset from a directory tree for a segmentation task.

Assumes a directory structure where a top-level directory can have subdirectories named "training", "validation" and "test" (possibly not all present), each of which can have images and ground truth in different subdirectories (named "images" and "ground_truth") or in the same directory. If the ground truth images have a particular suffix or a different extension (necessary if they are in the same directory as the images) it's necessary to specify it in the constructor. For more detailed information about the supported directory structure check https://github.com/deephealthproject/ecvl/wiki/ECVL-Dataset-Generator.

Constructor & Destructor Documentation

◆ GenerateSegmentationDataset()

ecvl::GenerateSegmentationDataset::GenerateSegmentationDataset	(	const filesystem::path &	dataset_root_directory,
		filesystem::path	suffix = `""`,
		filesystem::path	gt_name = `""`
	)

inline

GenerateSegmentationDataset constructor.

Parameters

[in]	dataset_root_directory	path containing the root directory of the dataset.
[in]	suffix	suffix or extension of ground truth images, necessary if it's different from corresponding images (e.g., "_segmentation.png" or ".png").
[in]	gt_name	name of the ground truth for images that share the same ground truth. All images in the split (if available) which don't have their own ground truth will use this one.

Member Function Documentation

◆ LoadSplitImages()

virtual int ecvl::GenerateSegmentationDataset::LoadSplitImages ( const filesystem::path & split )

overridevirtual

Load the path of images and labels of the specified split.

Parameters

[in] split directory name of the split that we are considering.

Returns: The number of samples of the split.

Implements ecvl::GenerateDataset.
