Anonymization Workflow for 1st and 2nd-floor Cameras
Videos in this directory are outputs of the COSMOS YOLOv4 blurring pipeline.
Faces and license plates are anonymized with Gaussian blurred areas defined by bounding box detection coordinates. A high-level overview of the blurring is as follows:
- Frames are read individually from a video file.
- Each frame is then:
2.1 Resized to the input size of the specific YOLOv4 model (960x960 or 1440x1440)
2.2 Passed through the YOLOv4 model which outputs bounding box predictions
2.3 Blurred corresponding to the bounding box predictions
- Blurred frames are written to the output video file.
The YOLOv4 blurring model is trained in Darknet on the Mudd 1st floor video dataset annotated in Summer 2021. Models are converted from Darknet to Pytorch for integration into the current implementation of the blurring pipeline.
