panoptica 0.5.5

Panoptic Quality (PQ) computation for binary masks.

Panoptica

Computing instance-wise segmentation quality metrics for 2D and 3D semantic- and instance segmentation maps.

Features

The package provides 3 core modules:

1. Instance Approximator
2. Instance Matcher
3. Panoptic Evaluator

Installation

To install the current release, you can simply run:

pip install panoptica

Use Cases

Semantic Segmentation Input

Although for many biomedical segmentation problems, an instance-wise evaluation is highly relevant and desirable, they are still addressed as semantic segmentation problems due to lack of appropriate instance labels.

Modules [1-3] can be used to obtain panoptic metrics of matched instances based on a semantic segmentation input.

Unmatched Instances Input

It is a common issue that instance segementation outputs have good segmentations with mismatched labels.

For this case modules [2-3] can be utilized to match the instances and report panoptic metrics.

Matched Instances Input

Ideally the input data already provides matched instances.

In this case module 3 can be used to directly report panoptic metrics without requiring any internal preprocessing.
