Automatic selection of eye tracking variables in visual categorization in adults and infants

no code implementations28 Oct 2020 Samuel Rivera, Catherine A. Best, Hyungwook Yim, Dirk B. Walther, Vladimir M. Sloutsky, Aleix M. Martinez

With its tight link to visual attention, eye tracking is a promising method for getting access to the mechanisms of category learning.

Cross-Cultural and Cultural-Specific Production and Perception of Facial Expressions of Emotion in the Wild

no code implementations13 Aug 2018 Ramprakash Srinivasan, Aleix M. Martinez

Yet, the study of emotion requires knowing which facial expressions are used within and across cultures in the wild, not in controlled lab conditions; but such studies do not exist.

Learning Facial Action Units From Web Images With Scalable Weakly Supervised Clustering

no code implementations CVPR 2018 Kaili Zhao, Wen-Sheng Chu, Aleix M. Martinez

We present a scalable weakly supervised clustering approach to learn facial action units (AUs) from large, freely available web images.

Recognition of Action Units in the Wild With Deep Nets and a New Global-Local Loss

no code implementations ICCV 2017 C. Fabian Benitez-Quiroz, Yan Wang, Aleix M. Martinez

Most previous algorithms for the recognition of Action Units (AUs) were trained on a small number of sample images.

EmotioNet Challenge: Recognition of facial expressions of emotion in the wild

no code implementations3 Mar 2017 C. Fabian Benitez-Quiroz, Ramprakash Srinivasan, Qianli Feng, Yan Wang, Aleix M. Martinez

The second track tested the algorithms' ability to recognize emotion categories in images of facial expressions.

EmotioNet: An Accurate, Real-Time Algorithm for the Automatic Annotation of a Million Facial Expressions in the Wild

no code implementations CVPR 2016 C. Fabian Benitez-Quiroz, Ramprakash Srinivasan, Aleix M. Martinez

Herein, we present a novel computer vision algorithm to annotate a large database of one million images of facial expressions of emotion in the wild (i. e., face images downloaded from the Internet).
