“…It allows visualization of morphological structures not visible to the naked eye. By magnifying the lesion and reducing the surface reflection, dermatoscopy aids in identifying key features like pigmentation patterns, vascular structures, and specific dermal structures, which are crucial for accurate diagnosis [ 7 ]. Early detection of skin lesions is critical for several reasons.…”

Skin cancer is one of the most fatal skin lesions, capable of leading to fatality if not detected in its early stages. The characteristics of skin lesions are similar in many of the early stages of skin lesions. The AI in categorizing diverse types of skin lesions significantly contributes to and helps dermatologists to preserve patients’ lives. This study introduces a novel approach that capitalizes on the strengths of hybrid systems of Convolutional Neural Network (CNN) models to extract intricate features from dermoscopy images with Random Forest (Rf) and Feed Forward Neural Networks (FFNN) networks, leading to the development of hybrid systems that have superior capabilities early detection of all types of skin lesions. By integrating multiple CNN features, the proposed methods aim to improve the robustness and discriminatory capabilities of the AI system. The dermoscopy images were optimized for the ISIC2019 dataset. Then, the area of the lesions was segmented and isolated from the rest of the image by a Gradient Vector Flow (GVF) algorithm. The first strategy for dermoscopy image analysis for early diagnosis of skin lesions is by the CNN-RF and CNN-FFNN hybrid models. CNN models (DenseNet121, MobileNet, and VGG19) receive a region of interest (skin lesions) and produce highly representative feature maps for each lesion. The second strategy to analyze the area of skin lesions and diagnose their type by means of CNN-RF and CNN-FFNN hybrid models based on the features of the combined CNN models. Hybrid models based on combined CNN features have achieved promising results for diagnosing dermoscopy images of the ISIC 2019 dataset and distinguishing skin cancers from other skin lesions. The Dense-Net121-MobileNet-RF hybrid model achieved an AUC of 95.7%, an accuracy of 97.7%, a precision of 93.65%, a sensitivity of 91.93%, and a specificity of 99.49%.

“…At the same time, new imaging devices such as super-high magnification dermoscopy and fluorescence advanced dermoscopy will allow a democratization of this optical microscopic in vivo approach thanks to their lower prices and the possibilities of observing single skin cells. 3 Optical images provided by RCM, LC-OCT, magnified dermatoscopy or multiphoton microscopy, due to the fineness of their definition and their contrasts, are more attractive than the ultrasound image which can appear out of focus. However, they do not allow us to observe the deeper part of the skin, which is for example relevant to define the thickness of a tumour with the consequent proper management and prognosis (see Breslow index).…”
