Struct RDKnee 

pub struct RDKnee {
    pub bpp: f64,
    pub quality: f64,
    pub fixed_angle: f64,
    pub norm: NormalizationContext,
}

The 45° tangent point on a corpus-aggregate R-D curve.

Computed using per-curve normalization (where the slope = 1 in normalized space), then placed in the fixed frame as a landmark angle.

Fields

bpp: f64

Bits per pixel at the knee (raw).

quality: f64

Quality metric value at the knee (raw units).

fixed_angle: f64

Angle of this knee in the fixed-frame corner system (degrees). Computed from FixedFrame::s2_angle or FixedFrame::ba_angle.

norm: NormalizationContext

The per-curve normalization context used for knee detection.
