Diagnostic Accuracy Of Content-Based Dermatoscopic Image Retrieval With Deep Classification Features
The utilization of dermoscopic images for the study and diagnosis of skin-related diseases is a essential resource for the early detection of life-threatening skin diseases such as melanoma. Artificial intelligence (AI) is a powerful tool  to assist in the classification of skin images with the use of convolutional neural networks (CNNs) while providing a high degree of accuracy to assist medical professionals in the identification and diagnosis of skin lesions. Visual features learned by a CNN, known as “deep features”, play a key role in identifying visually similar dermatoscopic images.

This work focuses on comparing the diagnostic accuracy of CNN trained for classification against results obtained from a more interpretable content-based image retrieval (CBIR) method. This involves querying a target image against a dataset of previously identified lesions. CBIR was tested using dermatoscopic images from three different datasets, and while the power of CNNs has been extensively used in the classification of skin imaging, results show that a CBIR-based method can reach similar performance to that of a classification network. However, this approach offers the added value of enabling CNNs to recognize unknown disease classes in new datasets, thus helping to improve diagnostic accuracy in a routine clinical setting.

Multimodal Skin Lesion Classification Using Deep Learning
AI technology has allowed for the accurate identification of skin lesions through the implementation of convolutional neural networks (CNNs). Traditionally, systems render a diagnosis  based on a single macroscopic image, the following study utilizes multiple imaging modalities with the combination of patient metadata in a multi-analytic approach with the goal of improving the performance of automated skin lesion diagnosis. Additionally, the system was tested in a five class classification task in order to better resemble a real-life clinical scenario. Results demonstrate the system outperforms both the baseline classifier utilizing a single macroscopic image when performing  multiclass classification.
