Face deidentification with generative deep models (FaceGEN)


The research project “Face deidentification with Generative Deep Models” (FaceGEN), strives to conduct research on deidentification technology and visual privacy with a particular focus on deep learning, which has recently been shown to be a highly effective tool for various computer vision and machine learning problems. Our goal is to develop deep generative models and conditional face synthesis techniques that can be used for deidentification and privacy protection with still images, but also with video, where multiple faces in cluttered and unconstrained scenes may appear in the data. The main tangible results of the project will be novel generative deep models and input-conditioned image synthesis techniques that are able to deidentify all parts of the facial data photo-realistically and ensure higher levels of privacy for users.

FaceGEN is a fundematal research project funded by the Slovenian Research Agency (ARRS) in in the period: 1.7.2019 – 31.6.2022 (1,66 FTE per year).

The Principal Investigator (PI) of FaceGEN is Assoc. Prof. Vitomir Štruc, PhD.

Project overview

FaceGEN is structured into 7 work packages:

  • WP1: Project management
  • WP2: Prerequisites
  • WP3: Face synthesis with generative models
  • WP4: Face alteration with gradient ascent
  • WP5: Face deidentification in video data
  • WP6: Demo room and exploitation
  • WP7: Dissemination

The R&D work on this work packages is expected to result in:

  • Formal privacy schemes based on deep models
  • Photo-realistic face synthesis techniques
  • Novel deidentification methods for image and video data

Project phases
