Gray-Level Co-occurrence Matrix (GLCM) Implementation and Feature Extraction

This implementation provides a functional Gray-Level Co-occurrence Matrix (GLCM) with feature parameter calculation, developed for academic research purposes. The code generates GLCM and computes multiple texture features including: f1 (Angular Second Moment), f2 (Contrast), f3 (Correlation), f5 (Inverse Difference Moment), f6 (Sum Average), f7 (Sum Variance), f9 (Difference Average), and f10 (Difference Variance). Though not perfect, it has been successfully validated in practical applications.
