Causal Inference in Multisensory Heading Estimation. [PDF]
PLoS ONE, 2017 A large body of research shows that the Central Nervous System (CNS) integrates multisensory information. However, this strategy should only apply to multisensory signals that have a common cause; independent signals should be segregated.

A linear perception-action mapping accounts for response range-dependent biases in heading estimation from optic flow. [PDF]
PLoS Computational BiologyAccurate estimation of heading direction from optic flow is a crucial aspect of human spatial perception. Previous psychophysical studies have shown that humans are typically biased in their heading estimates, but the reported results are inconsistent ...

Effect of range of heading differences on human visual-inertial heading estimation. [PDF]
Exp Brain Res, 2019 Both visual and inertial cues are salient in heading determination. However, optic flow can ambiguously represent self-motion or environmental motion. It is unclear how visual and inertial heading cues are determined to have common cause and integrated vs perceived independently.

Multi-Task Head Pose Estimation in-the-Wild [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2021 We present a deep learning-based multi-task approach for head pose estimation in images. We contribute with a network architecture and training strategy that harness the strong dependencies among face pose, alignment and visibility, to produce a top performing model for all three tasks.
