Color texture classification based on gravitational collapse
Texture and color are essential attributes to be analyzed for any robust computer vision system. This paper presents a novel method to analyze color-texture images, based on representing states of a simplified gravitational collapse from each image color channel and extracting information from each state using the BouligandMinkowski fractal dimension and the lacunarity method. In this approach, we obtained the best classification results when the images of each channel evolved in times t={1,5,10,15} t = { 1 , 5 , 10 , 15 } , each time representing a state, using radius r={3,4,5,6} r = { 3 , 4 , 5 , 6 } for the BouligandMinkowski method and box size l={2,3,4,5,6} l = { 2 , 3 , 4 , 5 , 6 } for the lacunarity method. The best classification results were 99.37% and 96.57% of success rate (percentage of samples correctly classified) for VisTex and USPTex databases, respectively. These results prove that the proposed approach opens a promising source of research in color texture analysis still to be explored.
