Artificial Pupil Dilation for Data Augmentation in Iris Semantic Segmentation
Daniel P. Benalcazar, David A. Benalcazar, Andres Valenzuela
Biometrics is the science of identifying an individual based on their intrinsic anatomical or behavioural characteristics, such as fingerprints, face, iris, gait, and voice. Iris r…
Presence-absence estimation in audio recordings of tropical frog communities
Andrés Estrella Terneux, Damián Nicolalde, Daniel Nicolalde +1
One non-invasive way to study frog communities is by analyzing long-term samples of acoustic material containing calls. This immense task has been optimized by the development of M…
An observational signal of the void shape correlation and its link to the cosmic web
Jounghun Lee, Fiona Hoyle
The shapes of cosmic voids are prone to distortions by the external tidal forces since their low-densities imply a lower internal resistance. This susceptibility of the void shapes…
