PPEDCRF: Privacy-Preserving Enhanced Dynamic CRF

PPEDCRF is a framework for location-privacy protection in dashcam videos. It identifies and tracks location-sensitive background regions using a dynamic Conditional Random Field (CRF) and applies calibrated perturbations to these regions while preserving foreground detection and segmentation utility. This repository contains the sensitive-region predictor (SensNet) component of the framework.
