The Anatomical Record, Volume 306, Issue 1, Page 5-28, January 2023., 2023 Abstract Antlers are the most conspicuous trait of cervids and have been used in the past to establish a classification of their fossil and living representatives. Since the availability of molecular data, morphological characters have generally become less important for phylogenetic reconstructions.

Handgun detection using combined human pose and weapon appearance [PDF]
IEEE Access, Volume 9 (2021) 123815 - 123826, 2020 Closed-circuit television (CCTV) systems are essential nowadays to prevent security threats or dangerous situations, in which early detection is crucial. Novel deep learning-based methods have allowed to develop automatic weapon detectors with promising results. However, these approaches are mainly based on visual weapon appearance only.
