GLCM Operator Description

Overview

Name:	`GLCM`
Full name:	`org.esa.snap.raster.gpf.texture.GLCMOp`
Purpose:	Extract Texture Features
Version:	1.0

Description

The operator extracts 10 texture features using GLCM: 1. Contrast 2. Dissimilarity (DIS) 3. Homogeneity (HOM) 4. Angular Second Moment (ASM) 5. Energy 6. Maximum Probability (MAX) 7. Entropy (ENT) 8. GLCM Mean 9. GLCM Variance 10. GLCM Correlation
