Introduction

AIStron is an open-source toolbox that provides current Amodal Instance Segmentation (AIS) methods. It is built as a project using detectron2 (version 0.6) and requires PyTorch 1.8+ or higher. The goal of AIStron is to combine the features of various AIS repositories and align them to facilitate easy maintenance and development of new methods.

Major features:

  • Data pipeline: We aim to standardize the annotations of existing AIS datasets so that the methods can be easily implemented and generalized. This diagram illustrates the data pipeline of aistron

  • Amodal Instance Segmentation Evaluator: AIStron helps compute the performance of both visible and amodal masks. If a method provides both pred_visible_masks and pred_amodal_masks in its predictions, both performances will be computed. If only the conventional pred_masks are provided, only the amodal performance is computed.

  • Utilities: We offer an amodal visualizer utility that allows you to visualize the ground truth or predictions with option to choose between visible masks, occluder masks and amodal masks.

  • Builtin-Methods:

  • Methods using aistron as library:
