Gradients distribution matrices and lacunarity in the capacity of texture measures of SAR and UAVs images

This article gives a brief description of two widely used texture measures of SAR and UAVs images. They are gradients distribution or co-occurrence matrices and lacunarity. We also provide detailed outlines of mentioned above matrices calculation in order to introduce the way of texture features extraction. At the end of the article, we examine functional connection between the first texture feature and absolute value of offset.
