Skin cancer (melanoma) is one of the most aggressive cancers and prevalence has significantly increased due to exposure ultraviolet radiation. Therefore, timely detection management lesion a critical consideration in order improve lifestyle reduce mortality. To this end, we have designed, implemented analyzed hybrid approach entailing convolutional neural networks (CNN) local binary patterns (L...

Skin cancer is the most common human malignancy according to American Cancer Society. It primarily diagnosed visually, starting with an initial clinical screening and followed potentially by dermoscopic (related skin) analysis, a biopsy histopathological examination. occurs when errors (mutations) occur in DNA of skin cells. The mutations cause cells grow out control form mass aim this study wa...

The shift between the source and target domains is main challenge in cross-domain few-shot learning (CD-FSL) tasks. However, domain unknown during training domain, which results a lack of directed guidance for We observe that, owing to similar backgrounds domains, self-labelled samples can be applied as prior tasks transfer knowledge onto Accordingly, we propose task-expansion-decomposition fra...

An effective way to improve the performance of deep neural networks in most computer vision tasks is quantity labeled data and quality labels. However, analysis processing medical images, high-quality annotation depends on experience professional knowledge experts, which makes it very difficult obtain a large number annotations. Therefore, we propose new semi-supervised framework for image clas...
