• Retinal noise emulation: a novel artistic tool for cinema that also improves compression efficiency

  Zabaleta, Itziar; Cámara, Mateo; Díaz, César; Canham, Trevor; García, Narciso; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2020)

  In cinema it is standard practice to improve the appearance of images by adding noise that simulates film grain. This is computationally very costly, so it is only done in post-production and not on the set. It is also ...
• Round or rectangular tables for collaborative problem solving? A multimodal learning analytics study

  Vujovic, Milica; Hernández Leo, Davinia; Tassani, Simone; Spikol, Daniel (Wiley, 2020)

  The current knowledge of the effects of the physical environment on learners’ behaviour in collaborative problem‐solving tasks is underexplored. This paper aims to critically examine the potential of multimodal learning ...
• Identification protocols and signature schemes based on supersingular isogeny problems

  Galbraith, Steven D.; Petit, Christophe; Silva, Javier (Springer, 2020)

  We present signature schemes whose security relies on computational assumptions relating to isogeny graphs of supersingular elliptic curves. We give two schemes, both of them based on interactive identification protocols. ...
• Active bilingualism delays the onset of mild cognitive impairment
