The design criteria, largely influenced by early vision processing, are discussed. VIKNET is formally described as an algebraic structure, with network functions defined on it. The input image, also in the form of a network, is recognized

One interesting fractal parameter is the fractal dimension that characterizes the roughness of the image. Higher-order fractal dimensions called multifractal dimensions are used to characterize the underlying inhomogeneity of texture in an image. This note deals with the methods of estimating fractal and multifractal dimensions of gray-tone digital images. Experimental

The technique is based on four texture features derived using the fractal geometry of images. These four features are fractal dimension (FD) of the original image, FD of above average (high) gray level image, ...

This feature is used in texture segmentation and classification, shape analysis and other problems. An efficient differential box-counting approach to fractal dimension estimation is proposed and compared with four other methods
