Expand description

Chroma-plane statistics of the changed pixels, all normalized to 255. Separates recolors (coherent, smooth chroma movement) from content replacements (scattered chroma) on photographic edits where luminance correlation alone saturates.

Fields§

§mean_abs_dy: f32

Mean |ΔY| (luminance delta magnitude).

§mean_dy: f32

Signed mean ΔY — a recolor often pushes luminance consistently in one direction, while a replacement balances out.

§mean_abs_di: f32

Mean |ΔI|.

§mean_abs_dq: f32

Mean |ΔQ|.

§mean_abs_dc: f32

Mean chroma-delta magnitude √(ΔI²+ΔQ²).

§chroma_cos: f32

Cosine between the chroma vectors of img1 and img2, weighted by their magnitudes. Near 1 = same hues, negative = coherent hue rotation.

§sat1: f32

Mean chroma magnitude (saturation) in img1.

§sat2: f32

Mean chroma magnitude in img2.

§chroma_rough: f32

Roughness of the chroma-delta field: mean |∇|Δc|| between adjacent changed pixels over the std of |Δc|. Low = smooth recolor, high = patchy replacement.
