Harmonic Radial Pre-Filtering for Medical Image Classification: An Empirical Study of Tusi-Couple-Derived Sampling on Mammography and Colonoscopy

We study a deterministic, parameter-free pre-processing transform that resamples a 2D image crop into a structured (angle × radius) grid using a phase-delayed harmonic radial sampling scheme derived from the geometry of the Tusi couple, a 13th-century mechanical construction in w...
