A review on the attention mechanism of deep learning

TL;DR: An overview of the state-of-the-art attention models proposed in recent years is given and a unified model that is suitable for most attention structures is defined.
Journal ArticleDOI

Facial expressions of emotion are not culturally universal

TL;DR: By refuting the long-standing universality hypothesis, the data highlight the powerful influence of culture on shaping basic behaviors once considered biologically hardwired and open a unique nature–nurture debate across broad fields from evolutionary psychology and social neuroscience to social networking via digital avatars.
Journal ArticleDOI

Underwater image enhancement via extended multi-scale Retinex

TL;DR: This paper presents a novel method for underwater image enhancement inspired by the Retinex framework, which simulates the human visual system and utilizes the combination of the bilateral filter and trilateral filter on the three channels of the image in CIELAB color space according to the characteristics of each channel.
Journal ArticleDOI

Gesture recognition based on binocular vision

TL;DR: According to the cloud image information, it can be judged that the binocular vision system can effectively segment the gesture from the complex background.
Journal ArticleDOI

A hybrid spatio-temporal model for detection and severity rating of Parkinson’s Disease from gait data

TL;DR: A machine learning based method to automatically rate the PD severity from gait information, in particular, the sequential data of Vertical Ground Reaction Force recorded by foot sensors is proposed, which outperforms existing ones in terms of prediction accuracy of PD severity levels.
