ToFMark - Depth Upsampling Evaluation Dataset

Welcome to the ToFMark evaluation page. This website is built to validate, compare and evaluate different depth image upsampling/superresolution algorithms. The basic principle is to use a low-resolution Time-of-Flight (ToF) depth acquisition together with a high-resolution intensity image.

Because depth and intensity data do not originate from the same sensor, these depth and intensity information are not aligned. Each ToFMark validation dataset includes:
  • a low-resolution offset corrected ToF depth and infrared image
  • a high-resolution intensity image
  • the ToF and intensity camera matrices
  • the sparse ToF depth mapped to the intensity camera system and
  • the correponding high-resolution ground-truth depth
