Dermoscopy in general practice: insights for clinical use and training
… benign skin lesions can mimic melanoma.<br/><br/>Dermoscopy is an examination tool that can improve the accuracy of skin lesion assessments. It uses a magnification lens and internal light source to facilitate a more detailed skin examination than is possible with the naked eye. However to date it …

THRESHOLDING METHODS FOR LESION SEGMENTATION OF BASAL CELL CARCINOMA IN DERMOSCOPY IMAGES
… algorithms that perform poorly on dermoscopy images of basal cell carcinoma (BCC), which is the most common skin cancer. One of the reasons for poor lesion detection performance is that there are very few algorithms that detect BCC borders, because they are difficult to segment, …

Automatic detection of lesion border and edge-related structures in dermoscopy images
… rate. As pre-processing steps of digital dermoscopy images in an automatic diagnosis system, line structure identification and lesion border identification algorithms are important for accuracy of diagnosis. This work presents the methodology and procedures to process dermoscopy images …

Evaluating the use of Dermoscopy in the Primary Care Setting in Improving Clinical Outcomes in the Treatment of Melanoma: A Systematic Review
… diagnoses, and initiate referrals/treatments. Dermoscopy, which is a magnification technique using visible light, is increasingly being used in the primary care setting as a tool to improve diagnostic accuracy. Dermoscopy training and the use of teledermoscopy in primary care settings are …

Automated classification of malignant melanoma based on detection of atypical pigment network in dermoscopy images of skin lesions
“Melanoma causes more deaths than any other form of skin cancer. Early melanoma detection is important to prevent progression to a more deadly stage. Automated computer-based identification of melanoma from dermoscopic images of skin lesions is the most efficient method in early diagnosis. An …

Aspects of skin cancer diagnosis in clinical practice
… the lowest for the arms. When the ABCD rule of dermoscopy was used preoperatively at the bedside in 309 cases (46 melanomas and 263 naevi), use of the algorithm achieved 83% sensitivity and 45% specificity for melanoma diagnosis. A sensitivity of 74% and specificity of 91% were seen for the …

Computer Aided Diagnosis Systems for Digital Analysis of Osteosarcoma and Skin Cancer
… in other modalities such as histology and dermoscopy is very recent. This dissertation focuses on the development of CAD systems for these modalities and includes (1) NAS: Deep Learning-Based Necrosis Assessment System for Osteosarcoma Histology Images, and (2) AlgoDerm: Deep Learning …

Segmenting Skin Lesion Attributes in Dermoscopic Images Using Deep Learing Algorithm for Melanoma Detection
… The image technique to diagnose skin cancer is dermoscopy, which leads to improved diagnose accuracy compared to traditional ABCD criteria. But reading and examining dermoscopic images is a time-consuming and complex process. Therefore, computerized analysis methods of dermoscopic images have …

Automatic Recognition of Buruli Ulcer Images on Smart Handheld Devices
Buruli ulcer (BU) disease is a devastating flesh eating bacterial infection that each year affects thousands of people in tropical and subtropical regions. Clinically, BU usually starts as a painless subcutaneous nodule, or as other pre-ulcer forms including papule, plaque, and edema; then it …
