Patent ID: 7215829

Claim:
A method of recognizing an object in a digital image, the method comprising: generating fractal map of the image including estimating a fractal dimension for at least one pixel of the image, the fractal dimension of the pixel given by d p = log ⁡ ( N 2 / N 1 ) log ⁡ ( L 2 / L 1 ) where d p is the fractal dimension of the at least one pixel of the image, N 2 is the sum of the pixel values in an L 2 ×L 2 structuring element, N 1 is the sum of the pixel values in an L 1 ×L 1 structuring element, and L 2 and L 1 are the sizes (in pixels) of the respective structuring elements; isolating the object by segmenting the fractal map; locating the object on the fractal map; and confirming the object based on pixel value of a pixel at a corresponding location in the digital image.
