Efficient approach to compute fractal dimension in SAR images

DBC and MDBC lose a lot of information when estimating the fractal dimension of an image. In order to overcome sue defect, a modified DBC, named GDBC is proposed, which takes use of the mean gray level of an image. Experiments are designe in three aspects to compare GDBC and the other two methods. The results suggest that GDBC is better than other two.
