Release Notes - CVEDIA-RT 2023.1.0



  • Trigger and Zone name included in the events
  • Motion guided detection has been improved to merge attention areas
  • Ability to get classified motion regions
  • Zones and Tripwires now return information about triggered objects
  • Improved tripwire crossing results for night-time low-fps footage
  • Fixed an issue where a zone would stop counting after the video loops
  • Tuned the thermal instance where the tripwire was counting the bike but not the person
  • Added option to export events in json without crops on separate files
  • Added a mixed model to the detector variant
  • Disabled 'filter edge detections' when not using multiple inference regions


We added a powerful tool for testing and comparing different neural networks, whether you are using predefined models from CVEDIA's ModelForge or your own custom networks in ONNX format.

With its easy-to-use interface, you can configure the networks to be tested, visualize the results, and compare the outputs of two networks. You can test and compare object detectors, classifiers, or 3D bounding box regressors.
