...that after Parker Brothers executives turned down the game of Monopoly because it had "52 fundamental errors" (including taking too long to play), a copy of the game wound up in the home of the company president who stayed up until 1 a.m. to finish playing it? He was so impressed by the game that the next day he wrote to inventor Charles Darrow and offered to buy it!

AbstractA method for registering a pattern image with a reference image is provided. The pattern image and the reference image differ from each other by a Rotation-Scale-Translation (RST) transformation defined by a scale factor s, a rotation factor $c;, and a translation vector (Ɗx, Ɗy). A Fourier-Mellin invariant is used to perform image registration by isolating the rotation, scale and transformation parameters of the RST transformation between the reference image r and the pattern image p.Other References
