What are textural features? In this example, the basic processing steps and the principle of textural feature analysis is illustrated. The feature Intensity Variability used in the example describes areas of similar intensity and is a measure of image (or tumor) heterogeneity; equivalent to the parameter Grey-Level Non-Uniformity for zone (GLNUz) used in the manuscript. Index H represents the number of homogenous zones in the volume of interest.
