Release Notes for HALCON 23.11.0.3 Progress

This document provides the release notes for MVTec HALCON 23.11.0.3 Progress, as released in February 2024, which is a Hotfix for HALCON 23.11.0.2 Progress. For general information like licensing or supported operating systems, see the release notes of HALCON 23.11.0.0 Progress.

Compatibility

  • A model calibrated with optimize_dl_model_for_inference in the fixed version and for the HAILO AI² Plugin can only be inferred by HALCON versions that also include the bug fix. The bug fix is compatible with all HAILO AI² Plugins that are compatible with the given HALCON version.

Detailed Description of Changes in HALCON 23.11.0.3 Progress (Hotfix)

The changes in HALCON 23.11.0.3 Progress are described with respect to HALCON 23.11.0.2 Progress.

General

  • Global Context Anomaly Detection (GC-AD) models could not be optimized correctly to HAILO-8 AI² Plugin and hardware. This hardware only allows int8 calibration precision. The calibration result showed faulty anomaly images, which led to very poor segmentation results and incorrect classification results. This problem has been fixed. Now, optimize_dl_model_for_inference converts the GC-AD models so that the quantitative results are very similar to full precision float32 models.
    It is necessary to calibrate GC-AD models with the new version again using optimize_dl_model_for_inference. It is also necessary to adjust the classification/segmentation thresholds for best results after calibration.
