Artificial Pupil Dilation for Data Augmentation in Iris Semantic Segmentation

1 code implementation 2022 IEEE Sixth Ecuador Technical Chapters Meeting (ETCM) 2022 Daniel P. Benalcazar, David A. Benalcazar, Andres Valenzuela

The results indicate that our data augmentation method can improve segmentation accuracy up to 15% for images with high pupil dilation, which creates a more reliable iris recognition pipeline, even under extreme dilation.

Selfie Periocular Verification using an Efficient Super-Resolution Approach

no code implementations16 Feb 2021 Juan Tapia, Andres Valenzuela, Rodrigo Lara, Marta Gomez-Barrero, Christoph Busch

Selfie-based biometrics has great potential for a wide range of applications since, e. g. periocular verification is contactless and is safe to use in pandemics such as COVID-19, when a major portion of a face is covered by a facial mask.
