Fania (Fanny) Kaplan and the attempted assassination of Vladimir Lenin: Ophthalmologic considerations

Acta Ophthalmologica, EarlyView.
Abstract Purpose Fania (Fanny) Kaplan (1890–1918), who was reportedly visually impaired, confessed to the attempted assassination of Soviet leader Vladimir Lenin (1870–1924) in 1918 by shooting him with a pistol. The precise nature of her visual loss is unknown and raises doubts about whether she had sufficient visual function to perform the act ...

The state of modelling face processing in humans with deep learning

British Journal of Psychology, EarlyView.
Abstract Deep learning models trained for facial recognition now surpass the highest performing human participants. Recent evidence suggests that they also model some qualitative aspects of face processing in humans. This review compares the current understanding of deep learning models with psychological models of the face processing system ...

PSHead: 3D Head Reconstruction from a Single Image with Diffusion Prior and Self‐Enhancement

Computer Graphics Forum, EarlyView.
We introduce PSHead, a coarse‐to‐fine framework guided by both object and face priors, to produce a Gaussian‐based 3D avatar for a single frontal‐view reference image. In the coarse stage, we create an initial 3D representation by applying diffusion models trained for general object generation, using Score Distillation Sampling losses over novel views.
