Annotation converter is a function which converts annotation file to suitable for metric evaluation format. Each annotation converter expects specific annotation file format or data structure, which depends on original dataset. If converter for your data format is not supported by Accuracy Checker, you can provide your own annotation converter. Each annotation converter has parameters available for configuration.
Process of conversion can be implemented in two ways:
Annotation conversion can be provided in dataset
section your configuration file to convert annotation inplace before every evaluation. Each conversion configuration should contain converter
field filled selected converter name and provide converter specific parameters (more details in supported converters section). All paths can be prefixed via command line with -s, --source
argument.
You can additionally use optional parameters like:
subsample_size
- Dataset subsample size. You can specify the number of ground truth objects or dataset ration in percentage. Please, be careful to use this option, some datasets does not support subsampling.annotation
- path to store converted annotation pickle file. You can use this parameter if you need to reuse converted annotation to avoid subsequent conversions.meta
- path to store mata information about converted annotation if it is provided.Example of usage:
The command line for annotation conversion looks like:
All converter specific options should have format --<parameter_name> <parameter_value>
You may refer to -h, --help
to full list of command line options. Some optional arguments are:
-o, --output_dir
- directory to save converted annotation and meta info.-a, --annotation_name
- annotation file name.-m, --meta_name
- meta info file name.Accuracy Checker supports following list of annotation converters and specific for them parameters:
wider

- converts annotation for SampleNet to ClassificationAnnotation
.data_dir
- path to sample dataset root directory.voc07
- converts Pascal VOC 2007 annotation for detection task to DetectionAnnotation
.image_set_file
- path to file with validation image list.annotations_dir
- path to directory with annotation files.images_dir
- path to directory with images related to devkit root (default JPEGImages).has_background
- allows convert dataset with/without adding background_label. Accepted values are True or False. (default is True)
voc_segmentation
- converts Pascal VOC annotation for semantic segmentation task to SegmentationAnnotation
.image_set_file
- path to file with validation image list.images_dir
- path to directory with images related to devkit root (default JPEGImages).mask_dir
- path to directory with ground truth segmentation masks related to devkit root (default SegmentationClass).mars
- converts MARS person reidentification dataset to ReidentificationAnnotation
.data_dir
- path to data directory, where gallery (bbox_test
) and query
subdirectories are located.market1501
- converts Market1501 person reidentification dataset to ReidentificationAnnotation
.data_dir
- path to data directory, where gallery (bounding_box_test
) and query
subdirectories are located.detection_opencv_storage
- converts detection annotation stored in Detection OpenCV storage format to DetectionAnnotation
.annotation_file
- path to annotation in xml format.image_names_file
- path to txt file, which contains image name list for dataset.label_start
- specifies label index start in label map. Default value is 1. You can provide another value, if you want to use this dataset for separate label validation.background_label
- specifies which index will be used for background label. You can not provide this parameter if your dataset has not background labelface_reid_pairwise
- converts Labeled Faces in the Wild dataset for face reidentification to ReidentificationClassificationAnnotation
.pairs_file

- path to file with annotation positive and negative pairs used for network train (optional parameter).landmarks_file
- path to file with facial landmarks coordinates for annotation images (optional parameter).landmarks_regression
- converts VGG Face 2 dataset for facial landmarks regression task to FacialLandmarksAnnotation
.landmarks_csv_file
- path to csv file with coordinates of landmarks points.bbox_csv_file
- path to cvs file which contains bounding box coordinates for faces (optional parameter).cityscapes
- converts CityScapes Dataset to SegmentationAnnotation
.dataset_root_dir
- path to dataset root.images_subfolder
- path from dataset root to directory with validation images (Optional, default imgsFine/leftImg8bit/val

.annotation_file
- path ot annotation file in json format.has_background
- allows convert dataset with/without adding background_label. Accepted values are True or False. (default is False).use_full_label_map
