Rate Distortion Curves

Benchmarked Codecs

  • RIDLE – baseline model with varying block size, quantization and resilience settings.
  • JPEG – MATLAB version with default parameters. Quality factor is varied.
  • JPEG2000 – MATLAB version with default parameters. Compression ratios are varied.
  • H.264 – x264 ffmpeg 4.0 version with main profile and constrained intra. Target bitrate varied. Slow Preset.
  • HEVC – x265 ffmpeg 4.0 with main (v2) profile and constrained intra. Target bitrate varied. Slow Preset.

Video Test Sequence

  • Single channel Long-Wave Infrared (LWIR) 8-bit depth imagery.
  • 640×480 spatial resolution.
  • 60 seconds at 30 frames per second (fps) totaling 1800 frames.
  • Bit errors modelled as flipped bits e.g. 0->1 or 1->0 with probability equal to the Bit Error Rate (BER).
  • Each video sequence is corrupted 10 times, and the average quality reported.
  • Similar results observed across a range of classified imagery.
