Advancing Melanoma Skin Cancer Detection with Novel Hybrid Deep Learning Systems
摘要
The growing prevalence of melanoma, the deadliest form of skin cancer, underscores the urgent need for automated and accurate diagnostic solutions. Manual diagnosis using dermoscopic images, though widely practiced, is time-intensive and demands a high level of expertise. To overcome these challenges, this research leverages hybrid deep learning approaches to enhance the early detection of melanoma. By combining convolutional neural networks (CNNs) with advanced recurrent networks such as GRU and LSTM, the proposed models effectively capture both spatial and sequential features from dermoscopic images. Three hybrid architectures—DenseNet201 + GRU + LSTM, Inception v3 + GRU + LSTM, and EfficientNetB4 + GRU + LSTM—were developed and evaluated using a Kaggle dataset. Among these, the EfficientNetB4 + GRU + LSTM model demonstrated superior performance, achieving an accuracy of 96.35%. The DenseNet201 + GRU + LSTM model achieved competitive results with an accuracy of 96%, while Inception v3 + GRU + LSTM achieved an accuracy of 94.76%. These results highlight the potential of hybrid architectures in handling variability in lesion appearance and imaging conditions. The proposed methodologies provide a robust and reliable solution for automated melanoma detection, significantly reducing the reliance on manual diagnosis. By addressing critical challenges in dermoscopic image analysis, these systems offer a promising avenue for supporting dermatologists in clinical decision-making and improving patient outcomes. This study advances the field of computer-aided diagnosis and emphasizes the transformative potential of these models in medical imaging.
