Random Forests and VGG-NET: An Algorithm for the ISIC 2017 Skin Lesion Classification Challenge [PDF]
arXiv, 2017 This manuscript briefly describes an algorithm developed for the ISIC 2017 Skin Lesion Classification Competition. In this task, participants are asked to complete two independent binary image classification tasks that involve three unique diagnoses of skin lesions (melanoma, nevus, and seborrheic keratosis).

Interpolated inverse discrete wavelet transforms in additive and non-additive spectral background correction [PDF]
arXiv, 2023 We demonstrate the applicability of using interpolated inverse discrete wavelet transforms as a general tool for modeling additive or multiplicative background or error signals in spectra. Additionally, we propose an unsupervised way of estimating the optimal wavelet basis along with the model parameters.

Melanoma Diagnosis in the Mihm Era—And Beyond
Journal of Cutaneous Pathology, EarlyView.ABSTRACT During the illustrious career of Martin C. Mihm Jr., MD, the diagnosis of melanoma underwent significant changes, to which he made many contributions. In early descriptions, melanomas were fungating tumor masses that were obviously malignant, and highly lethal. In seminal work by Dr. Mihm and his mentor, Wallace H.

Noninvasive identification of carbon-based black pigments with pump-probe microscopy [PDF]
Carbon-based black pigments, a widely used class of pigments, are difficult to differentiate with the noninvasive techniques currently used in cultural heritage science. We utilize pump-probe microscopy to distinguish four common carbon-based black pigments as pure pigments, as two-component black pigment mixtures, and as a mixture of a black and a ...

ganX -- generate artificially new XRF a python library to generate MA-XRF raw data out of RGB images [PDF]
arXiv, 2023 In this paper we present the first version of ganX -- generate artificially new XRF, a Python library to generate X-ray fluorescence Macro maps (MA-XRF) from a coloured RGB image. To do that, a Monte Carlo method is used, where each MA-XRF pixel signal is sampled out of an XRF signal probability function.

Pigmented trichoblastoma arising from the nevus sebaceous: a rare case in Korea.
Annals of Dermatology, 2009 Trichoblastoma is occasionally observed in association with a pre-existing nevus sebaceous in the Korean literature. However, there has been no report on the pigmented type.

Grading Melanocytic Dysplasia: Updated Histopathologic Criteria
Journal of Cutaneous Pathology, EarlyView.ABSTRACT Dr. Martin C. Mihm, Jr.'s innovative work on the dysplastic nevus achieved a milestone in his chapter in the World Health Organisation Classification of Skin Tumours (WHO‐C). WHO‐C presents a dichotomous classification (high‐grade versus low‐grade dysplastic nevi) and a quantitative metric to assess melanocytic nuclear enlargement.

Journal of Cutaneous Pathology, EarlyView.ABSTRACT Background Genomic fusions involving Protein Kinase C (PKC or PRKC) have been classically identified in a subset of melanocytic neoplasms with heavy melanin pigmentation as described in older series. They were recently reclassified from the pigmented epithelioid melanocytoma (PEM) category to the blue nevus (BN) category in the fifth edition ...

Complete regression of a melanocytic nevus after epilation with diode laser therapy
Dermatology Practical & Conceptual, 2015 The use of lasers and intense pulsed light (IPL) technology has become an established practice in dermatology and aesthetic medicine. The use of laser therapy and IPL in the treatment of pigmented melanocytic lesions is a controversial issue.

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.Summary Background and objectives Technical advances have allowed for significant improvements in imaging techniques in recent years. Specifically, lesions can now be depicted at a much higher magnification – up to 400 x – using optical super‐high magnification dermoscopy (OSHMD).
