Traditional methods often rely on expert visual assessments, which are labour-intensive, subjective, and time-consuming.

The second phase involves image segmentation using the Sauvola method. Following this, colour and texture featureextraction is performed. Colour features are extracted in the Hue (H), Saturation (S), and Value (V) colour space, while texture features are obtained using the Grey-Level Co-Occurrence Matrix (GLCM) method. This combination of colour and texture features results in various metrics, including mean, dissimilarity, skewness, angular second moment, variance, entropy, maximum probability, contrast, correlation, energy, and homogeneity, which are used for classification.
