In 1914, Blondel [1] performed an experiment in which a solenoidal coil was coaxial with a region of static magnetic field, such that the magnetic field on the conductor of the coil was negligible. The conductor of the coil T (D in the right figure) could be wound onto an auxiliary drum T ′ (D1), such that the magnetic flux through the coil T (D) was time dependent. What was the reading of the ...

The Bradford chromatic adaptation transform, empirically derived by Lam, models illumination change. Specifically, it provides a means of mapping XYZs under a reference light source to XYZs for a target light source such that the corresponding XYZs produce the same perceived color. One implication of the Bradford chromatic adaptation transform is that color correction for illumination takes pla...
