    For b=0, one still gets γ=2, for b=0.5 one gets γ=1, for b=1 one gets γ=0.5, but it is not a linear interpolation between these 3 images. The formula specified by recent W3C drafts [ 3 ] for SVG and Canvas is mathematically equivalent to the Photoshop formula with a small variation where b≥0.5 and a≤0.25:

    en.wikipedia.org/wiki/Speckle_variance_optical...

    Speckle variance optical coherence tomography (SV-OCT) is an imaging algorithm for functional optical imaging. Optical coherence tomography is an imaging modality that uses low-coherence interferometry to obtain high resolution, depth-resolved volumetric images.

  9. Specularity - Wikipedia

    en.wikipedia.org/wiki/Specularity

    In the context of seismic migration, specularity is defined as the cosine of the angle made by the surface normal vector and the angle bisector of the angle defined by the directions of the incident and diffracted rays. [3]
