Processing Notes — Pixel Error Value Ordering with CNN Predictor (Saini 2025)

  • Paper: Ankit Kumar Saini, Samayveer Singh, Signal, Image and Video Processing, vol. 19, 2025
  • Reproduction tier: A
  • Status: Completed (full reproduction)

What was reproduced

Error-ordered rhombus PEE core, levels 1..3, 8 images, bit-exact reversibility.

Reproduced vs reported

The PEVO/PEE mechanism and reversibility are reproduced. The CNN predictor is NOT trained (no weights/data available) and is approximated by a fixed rhombus predictor -> reproduced capacity is a conservative lower bound. This is stated openly.

Honesty note

No fabricated results; all numbers from included code; 'reported' cells reflect the paper.
