Problem addressed

The AI enabled solution can achieve one-to-many car plate recognition simultaneously, which is a cost saving solution to smart parking management system.

  • VistGAN – an unsupervised video super-resolution technique which reconstructions a high-resolution video sequence of grams from a low-resolution video sequence of frames.
  • The reconstruction makes use of a video super-resolution approach with temporal consistency using Generative Adversarial Networks (GAN), an unsupervised learning mode, and a metric learning model in its discriminator which maps degradation operations of the low-resolution frames.
Key impact
  • Higher video quality up to 26.78 Peak SNR
  • Reduce CAPEX on hardware installation (10 camera into 1)
  • Flexible installation for public parking area
  • AI model and OCR running on the IoT edge
  • Indoor Carpark – car plate recognition and way guiding
  • Outdoor Carpark – smart cities for parking space enquiry
