Introduction #

Released 2022-11-22 ·Utkarsh Pandey

The Recognizance’22 dataset is a collection of microscopic images in which individual cells have been meticulously segmented. Cell segmentation is a crucial initial stage in numerous biomedical investigations, forming a fundamental aspect of image-based cellular research. The shape and structure of a cell can provide essential insights into its physiological condition, and a precisely segmented image is vital for capturing biologically significant morphological details.

Summary #

Recognizance’22 Round 2 is a dataset for instance segmentation, semantic segmentation, and object detection tasks. It is used in the biological research.

The dataset consists of 1200 images with 6097 labeled objects belonging to 1 single class (cell).

Images in the Recognizance’22 Round 2 dataset have pixel-level instance segmentation annotations. Due to the nature of the instance segmentation task, it can be automatically transformed into a semantic segmentation (only one mask for every class) or object detection (bounding boxes for every object) tasks. There are 200 (17% of the total) unlabeled images (i.e. without annotations). There are 2 splits in the dataset: train (1000 images) and test (200 images). The dataset was released in 2022.
