This article describes the design, implementation, and results of latest installment dermoscopic image analysis benchmark challenge. The goal is to support research development algorithms for automated diagnosis melanoma, most lethal skin cancer. challenge was divided into 3 tasks: lesion segmentation, feature detection, disease classification. Participation involved 593 registrations, 81 pre-submissions, 46 finalized submissions (including a 4-page manuscript), approximately 50 attendees,...

This work summarizes the results of largest skin image analysis challenge in world, hosted by International Skin Imaging Collaboration (ISIC), a global partnership that has organized world's public repository dermoscopic images skin. The was 2018 at Medical Image Computing and Computer Assisted Intervention (MICCAI) conference Granada, Spain. dataset included over 12,500 across 3 tasks. 900 users registered for data download, 115 submitted to lesion segmentation task, 25 attribute detection...

The use of artificial intelligence (AI) is accelerating in all aspects medicine and has the potential to transform clinical care dermatology workflows. However, develop image-based algorithms for applications, comprehensive criteria establishing development performance evaluation standards are required ensure product fairness, reliability, safety.

Abstract AI image classification algorithms have shown promising results when applied to skin cancer detection. Most public datasets are comprised of dermoscopic photos and limited by selection bias, lack standardization, lend themselves development that can only be used skilled clinicians. The SLICE-3D (“Skin Lesion Image Crops Extracted from 3D TBP”) dataset described here addresses those concerns contains images over 400,000 distinct lesions seven dermatologic centers around the world....

Basal cell carcinoma (BCC) is the most common skin cancer. Dermoscopic imaging has improved diagnostic accuracy; however, diagnosis of nonpigmented BCC remains limited to arborizing vessels, ulceration, and shiny white structures.To assess multiple aggregated yellow-white (MAY) globules as a feature for BCC.In this retrospective, single-center, case-control study, tumors, determined clinically, were identified from database lesions consecutively biopsied during 7-year period (January 1,...

Background: The group of histopathologically aggressive BCC subtypes includes morpheaform, micronodular, infiltrative and metatypical BCC. Since these tumors are at increased risk recurring, micrographically controlled surgery is considered the best therapeutic option. Although dermoscopy significantly improves clinical recognition BCC, scarce evidence exists on their dermoscopic criteria. Aim: To investigate characteristics subtypes. Materials Methods: Dermoscopic images were analyzed for...

Dermoscopy is commonly used for the evaluation of pigmented lesions, but agreement between experts identification dermoscopic structures known to be relatively poor. Expert labeling medical data a bottleneck in development machine learning (ML) tools, and crowdsourcing has been demonstrated as cost- time-efficient method annotation images.The aim this study demonstrate that can label basic from images lesions with similar reliability group experts.First, we obtained labels 248 melanocytic 31...
