Closed-Form Solution to Disambiguate Defocus Blur in Single-Perspective Images

Depth-from-defocus techniques suffer an ambiguity problem where depth planes on opposite sides of the focal plane have identical defocus. We solve the ambiguity by relying on the wavelength-dependent relationship between defocus and depth. We conduct a robustness analysis and validation on consumer lenses.
