Abstract:
1. A method for discriminating objects in a digital image, said method comprising: automatically assigning to each pixel in the digital image a pixel value that represents the fractal dimension of the pixel to generate a fractal map, wherein the fractal dimension of a pixel (dp) is given by: wherein N 2 represents the sum of the pixel values in a L 2 ×L 2 structuring element and 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; segmenting the fractal map into two or more fractal images; and shrinking objects in the segmented fractal images.
