3D Face Synthesis Driven by Personality Impression

, 2018
Synthesizing 3D faces that give certain personality impressions is commonly needed in computer games, animations, and virtual world applications for producing realistic virtual characters. In this paper, we propose a novel approach to synthesize 3D faces

Modelling, Classification and Synthesis of Facial Expressions

, 2008
In this chapter we have discussed the field of facial expression analysis from both a Behavioural Science and a Computer Vision perspective. We introduced the field of facial expression analysis with Darwin's initial findings and then went on to provide details of the research conduced by Ekman et al.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

The role of hypothalamus-pituitary-adrenal (HPA)-like axis in inflammatory pilosebaceous disorders [PDF]

, 2020
Skin is the largest peripheral endocrine organ and functions as a hormone target and endocrine gland. A cutaneous hypothalamus-pituitary-adrenal (HPA)-like axis enables the skin to respond to stress and regulates its steroidogenic activity.

Morphological and transcriptional evaluation of multiple facial cutaneous hyperpigmented spots

Skin Health and Disease, 2022
Background Morphological characteristics of major facial hyperpigmented spots have been well documented. However, detailed alterations of respective transcriptional profile for each spot and in‐depth comparisons across multiple spot types have not been ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Machine Learning-Based Expression Generation Technology for Virtual Characters in Film and Television Art

International Journal of Computational Intelligence Systems
Facial expression generation played an essential role in virtual avatars, television, film art, and human–computer interaction. The existing synthesis model faces difficulties due to poor generalization, unnatural distortion, identity inconsistency, and ...

Text-based Editing of Talking-head Video

, 2019
Editing talking-head video to change the speech content or to remove filler words is challenging. We propose a novel method to edit talking-head video based on its transcript to produce a realistic output video in which the dialogue of the speaker has ...
