A growing need for healthcare treatments for skin conditions, melanoma, etc, in the medical prognosis for skin illnesses. The timely identification or precise diagnosis of skin conditions or illnesses can avert subsequent health issues. For categorizing skin illnesses across high-quality photos, a variety of statical image processing techniques, histogram equalization (HE), Gabor filters, morphological operations, and Gray-level co-occurrence matrix (GLCM) are often utilized. Deep models effectively train or learn the skin images to reliably classify skin diseases for photos with moderate to standard quality. In terms of precision and accuracy performance metrics, deep learning-based skin healthcare solutions pay closer attention than classic image processing techniques. Convolutional neural networks (CNN) and their extended derivations are prompted for the substantial skin illness categorization findings in medical healthcare related to skin diagnostics. Current CNN models, such as Basic CNN, Visual Geometric Group Deep CNN (VGG), Dense CNN (DenseNet), and Residual Neural Network (ResNet), are experimented on benchmarked skin disease datasets to analyze classification performance in terms of accuracy and loss.
