4.7 Did You Know?

"...this image has such lovely texture, don't you think?..."

...texture was identified as one of the key elements of visual interpretation (section 4.2), particularly for radar image interpretation. Digital texture classifiers are also available and can be an alternative (or assistance) to spectral classifiers. They typically perform a "moving window" type of calculation, similar to those for spatial filtering, to estimate the "texture" based on the variability of the pixel values under the window. Various textural measures can be calculated to attempt to discriminate between and characterize the textural properties of different features.
