Table 2. Texture Quantifiers Applied to Clinical Data.

		Energy	Entropy	Dissimilarity	Homogeneity	Mean-field Energy
15-bit image data	τ	-0.86	0.86	-0.54	0.69	0.78
	AUC	0.50	0.51	0.56	0.54	0.48
8-bit image data	τ	-0.85	0.85	-0.54	0.54	0.79
	AUC	0.50	0.50	0.56	0.55	0.47

Here, τ is Kendall’s measure of rank correlation with tumor volume and AUC is the area under the receiver-operating curve for binary treatment response.
