Texture Representation

The first texture descriptor we examine is based on a "gradient density" (GD) measure, and the second on an intensity variation (INV) measure.

FIGURE 2 Overcoming the problem of anisotropic sampling: (a) An image created originally with isotropic sampling, subsequently subsampled with rates 1:2:3. (b) Its orientation indicatrix if the anisotropic sampling is ignored. (c) Its orientation indicatrix if scaling is used.
