Abstract:
A method of recognizing an unknown object, including the steps of:receiving from a camera, a first image of said unknown object which is comprised of an array of pixels of several different magnitudes;generating a second image, after said first image is received, by scaling the pixel magnitudes in said first image such that a histogram of the pixels in said second image has a larger standard deviation than a histogram of the pixels in said first image;detecting an area in said second image where the pixel magnitudes exceed a certain minimum;generating a third image, after said second image is generated, by decreasing the magnification of said second image if said area has a width which exceeds a predetermined standard, and increasing the magnification of said second image if said area has a width which is less then said predetermined standard; and,identifying said unknown object as a particular object if a correlation between said third image and an image of said particular object exceeds a threshold.
