Coarse segmentation process for dental caries, (a) the normalized image represents the preprocessed X-ray image, ensuring consistent intensity levels across the image, (b) the closed image, generated during the preprocessing steps, further refines the image by eliminating small artifacts and smoothing the boundaries, (c) the coarse segmentation result, obtained using an enhanced FCM-FRWS algorithm with c = 3 clusters, significantly improves segmentation accuracy, effectively delineating regions of dental caries within the X-ray image.
