Productivity #18: Annotator Performance Management

Productivity #18: Annotator Performance Management

Every labeling job provides statistics for each annotator. Statistics include total number of labels for each class, number of accepted labels, number of rejected labels. Aggregated sum for all annotators is also available. StatisticsThe line charts show labeling time in seconds spent on each day, review time in seconds, number

Productivity #17: Window Level for DICOM and Nifti

Productivity #17: Window Level for DICOM and Nifti

CT and MRI dicom images can be viewed using multiple window settings in order to see different features of the image. For example, there would be different window settings to look at Abdominal / soft tissues, Bone, Brain, Liver, Lung, Subdural brain. The Window Center (0028,1050), Window Width (0028,1051)

Productivity #12: Add New Class During Annotation

Productivity #12: Add New Class During Annotation

When annotator is creating annotations, annotator might want to add a new class definition. Admin can allow annotator to add class under Project Settings --> Appearance --> Allow annotator to Annotator can add new class or edit existing labels by selecting + Add Class inside the annotation tool in

Productivity #11: Import PNG Mask as pre-labels

Productivity #11: Import PNG Mask as pre-labels

The annotation tool enables user to import PNG masks as pre-labels. This is fastest way to implement model assisted annotation without exposing your model's intellectual property. The input dataset should contain image files and one Png mask file per label as seen in the dataset below (import-prelabel-mask.csv) Image files

Productivity #10: Superpixel Size in Segmentation

Productivity #10: Superpixel Size in Segmentation

Superpixel segmentation in the annotation tool allows different sizes of Superpixel at different zoom levels. There is a trade-off between accuracy of annotation and time to annotation as the Superpixel size changes. Large Superpixel – Zoom outFor fast semantic segmentation annotator can zoom out on the image and perform Superpixel segmentation.

Productivity #9: Dataset with multiple folders

Productivity #9: Dataset with multiple folders

There are use cases like radiology where a radiologist would like to images from axial view, sagital view, coronal view in a single labeling project. To create a dataset with multiple folders first create an archive (zip or tar) file that preserves the folder structure including the image file. Create

Productivity #8: Multi Planar Views for Radiology

Productivity #8: Multi Planar Views for Radiology

Radiological datasets including MRI and CT-scans contain images from multiple planes like axial plane, coronal plane and sagittal plane. TraningData.io allows multi-planar views with upto four planes included in a single view as shown in the image below. The axial plane, coronal plane and sagital planes are synchronized with

Productivity #7: Review System

Productivity #7: Review System

The annotation tool has an annotation mode and a review mode. In review mode a reviewer can review every individual annotation. Review each individual annotationFor every annotation reviewer can accept or reject the annotation, give it a score between 0 and 10, and leave a comment for the annotator. When

Productivity #6: Image Queuing Strategy

Productivity #6: Image Queuing Strategy

In large industrial scale annotation projects, there are millions of images with multiple annotators participating. Images and videos can be distributed among the annotators using different distribution strategies. All the image & video assets to be labeled are stored in a queue. There are two separate queues for labeling and
