Attention-Driven Lightweight Model for Pigmented Skin Lesion Detection [PDF]
arXiv, 2023 This study presents a lightweight pipeline for skin lesion detection, addressing the challenges posed by imbalanced class distribution and subtle or atypical appearances of some lesions. The pipeline is built around a lightweight model that leverages ghosted features and the DFC attention mechanism to reduce computational complexity while maintaining ...

Nonphotosynthetic Pigments as Potential Biosignatures [PDF]
Astrobiology 15(5): 341-361 (2015), 2015 Previous work on possible surface reflectance biosignatures for Earth-like planets has typically focused on analogues to spectral features produced by photosynthetic organisms on Earth, such as the vegetation red edge. Although oxygenic photosynthesis, facilitated by pigments evolved to capture photons, is the dominant metabolism on our planet ...

Argon Laser Photoablation of Conjunctival Pigmented Nevus
American Journal of Ophthalmology, 2006 To evaluate the efficacy of an argon laser in the ablation of benign conjunctival pigmented nevi.Interventional case series.We conducted argon laser ablations for conjunctival pigmented nevus in 30 eyes of 28 patients. Laser ablation was applied directly to the conjunctival pigmented nevus in all patients. All patients were followed up over a period of
