DeepStack Beta - Release Notes

DeepStack Beta is more optimized for storage, memory, compute and is more accurate.

Improvements

• New Fast GPU Version

  We have released the GPU Version of DeepStack, accelerating responses by orders of magnitude if you have an Nvidia GPU. See Using DeepStack with NVIDIA GPU for setup instructions

• Improved Face Recognition Engine

  The face recognition API is now powered by state-of-the-art face recognition engine.

• Better error handling and crash recovery

  DeepStack now gracefully handles invalid images and reports errors better.

• 50% Reduction in Install Size

  The total install size DeepStack is now half the original size.

API Changes

• OBJECT DETECTION - MINIMUM CONFIDENCE

  By default, all objects with a confidence of 0.4 and above are detected. However, you can adjust the confidence level using the min_confidence parameter.

Breaking Changes

• ENDPOINT ACTIVATION

  To avoid unneccesary memory usage. Only endpoints you activate are loaded.

  For example, to use any face API, you should run deepstack as below

  sudo docker run -e VISION-FACE=True -v localstorage:/datastore \
  -p 80:5000 deepquestai/deepstack
  

  In this example, you can query all face related APIs, however, you cannot query the object detection API and other endpoints.

  You can activate multiple endpoints at once as below

  sudo docker run -e VISION-FACE=True -e VISION-SCENE=True -e VISION-TRAFFIC=True \
  -v localstorage:/datastore -p 80:5000 deepquestai/deepstack
  

• CONFIDENCE VALUES

  All endpoints now return confidence scores in range of 0 - 1. Previously, some endpoints returned confidence in range of 0 - 100

• FACE RECOGNITION API-MINIMUM CONFIDENCE

  The min_distance parameter has been replaced by min_confidence See Face Recognition for usage instructions

• FACE RECOGNITION API - DATA INCOMPATIBILITY

  Any faces registered with the Alpha Version is incompatible with this Version. You need to re-register previously registered faces. The new face recognition engine is stable and future releases will remain compatible with this Version.

• FACE RECOGNITION API - RESPONSES

  Face registeration response has been changed from

  {'predictions': {'message': 'face added'}, 'success': True}
  

  To

  {'message': 'face added', 'success': True}
  

  Face delete response has been changed from

  {'success': True, 'message': 'user deleted successfully'}
  

  To

  {'success': True}
  

• SCENE AND TRAFFIC API - RESPONSES

  Responses has been changed from

  {'success': True, 'predictions': [{'label': 'conference_room', 'confidence': 73.73981475830078}]}
  

  To

  {'success': True, 'confidence': 0.7373981, 'label': 'conference_room'}
  

• OBJECT DECTION API - SPEED MODES

  Speed Modes have been deprecated.
