Abstract
We describe a complex log mapping approach for 2-D color object recognition. First, a 3-D vector color image is transformed into a 2-D vector image by projection onto a color plane, then a complex log mapping transform is applied to this 2-D vector color image for invariant pattern recognition. Using extensive computer simulations, this method can effectively recognize a scale- and rotation-changed color object among objects of similar shape but with different color contents and also among objects of different shape and color.
