Pre-quantization channel decorrelation tested on Kodak kodim01 — 68.7% avg inter-channel correlation reduction, verified resolution-invariant . Data reorganization, not a new codec
Four-stage tridirectional redistribution (TRI) applied to Kodak Lossless True Color Image Suite kodim01. Each TRI stage processes a different channel pair, progressively reducing inter-channel correlation from 0.898 to 0.281.
TRI-2 shows a temporary correlation increase as variance is redistributed between channel pairs before final decorrelation at TRI-3/4.
The method was verified at both native Kodak resolution (768×512) and 2640×1760 — correlation values differ by 0.000047 across a 12× pixel count difference, confirming the effect operates at the individual pixel level independent of spatial resolution.
It requires no encoder modification or neural network — it operates as a pre-quantization data reorganization step
