READ (Reconstruction or Embedding based Anomaly Detection)

This repo is the mindspore version of READ, plz jump to https://git.openi.org.cn/OpenI/READ_pytorch for the pytorch version.

READ is an open source toolbox focused on unsupervised anomaly detection/localization tasks. By only training on the defect-free samples, READ is able to recognize defect samples or even localize anomalies on defect samples.

The purpose of this repo is to promote the research and application of unsupervised anomaly detection and localization algorithms. READ is designed to provide:

• A unified interface for encapsulating diverse anomaly localization algorithms
• High quality implementations of novel anomaly localization algorithms
• Templates for using these algorithms in a detailed task

In addition, READ provides the benchmarks for validating novel unsupervised anomaly detection and localization algorithms for MVTec AD dataset.

Changelog

• [Nov 07 2021] READ_mindspore v0.1.0 is Released!
  Please refer to ChangeLog for details and release history.
