Fastvideo SDK benchmarks

Debayer on CUDA

Main Points

  • Converts 8/16-bit Raw Bayer images to 24/48-bit RGB
  • Can do that really fast on NVIDIA GPU, much faster than on any CPU
  • High quality image debayering
  • Immediate time measurements for each algorithm
  • Makes comparison with etalon images and calculates PSNR/MSE

CUDA DebayerWhat's unique in GPU Debayer software

  • This is, probably, the fastest debayer
  • Sofisticated algorithms with high PSNR and low artifacts
  • Simple to use, fast to work and easy to check
  • Free for personal and educational (including non-profit organization) use
  • Testing tool to check quality, timing and performance of debayer algorithms prior to developing heavy loaded services for raw image processing
  • Bayer patternCreated by company with years of CUDA experience and world-class achievements in the field

GPU Debayer Software Features

  • All Bayer mosaic patterns for input data supported (RGGB, BGGR, GBRG, GRBG)
  • Mosaic algorithm to prepare CFA input image from any 24/48-bit PPM image
  • Read 8-bit input CFA image data from HDD/SSD/RAID in PGM format
  • Output format: 24/48-bit PPM
  • Minimum image resolution 128 x 128 pixels
  • Maximum image resolution up to 12k x 12k pixels
  • Debayer quality for the following algorithms:
    • HQLI debayer (High Quality Linear Interpolation, window 5×5) – avr. PSNR ~ 36 dB (SSIM ~ 0.965) for Kodak data set
    • L7 debayer (High Quality Linear Interpolation, window 7×7) – avr. PSNR ~ 37.1 dB (SSIM ~ 0.971) for Kodak data set
    • DFPD debayer (Directional Filtering and a Posteriori Decision, window 11×11) – avr. PSNR ~ 39 dB (SSIM ~ 0.978) for Kodak data set
    • MG debayer (Multiple Gradients, window 23×23) – avr. PSNR ~ 40.5 dB for Kodak data set
  • Peak performance (GPU computations only, for 4K resolution, 8-bit image, no batch, no streaming) on NVIDIA Quadro P6000:
    • HQLI debayer – up to 50 GPix/s
    • L7 debayer – up to 45 GPix/s
    • DFPD debayer – up to 18 GPix/s
    • MG debayer – up to 4 GPix/s
  • Quality measurements: MSE and PSNR
  • Timing and performance measurements for each algorithm
  • Batch mode, pyramid images and tiling for multiple camera systems with realtime image debayer – option
  • Command-line demo application for Windows-7/8/10 and Linux Ubuntu/CentOS
  • Compatibility with NVIDIA Jetson Nano, TX1, TX2 and NX/AGX Xavier
