Age estimation is a technique for predicting human ages from digital facial images, which analyzes a person's face image and estimates his/her age based on the year measure. ... In this case study, we overview the existing models, popular techniques, system performances, and technical challenges related to the facial image-based age synthesis and estimation topics. ... Fu and Zheng  have been presented a novel facial modeling framework (M-Face) based on appearance photorealistic of the multiple facial object class for emotional face September, 2018 rendering. ...arXiv:2002.03750v1 fatcat:ytm6uv5vsnhtvkbvbr3tyw5lga
Human age, as an important personal trait, can be directly inferred by distinct patterns emerging from the facial appearance. ... Existing models, popular algorithms, system performances, technical difficulties, popular face aging databases, evaluation protocols, and promising future directions are also provided with systematic discussions ... Fu and Zheng  presented the M-Face framework for appearance-based photorealistic facial modeling. The Aging Ratio Image (ARI) is captured from their aging database for texture rendering. ...doi:10.1109/tpami.2010.36 pmid:20847387 fatcat:fzucchc7mzhanl7n3lsy6sxhe4
In this thesis, we present a complete framework to inverse render faces with a 3D Morphable Model. ... This is achieved by incorporating statistical models for ambient occlusion and bent normals into the image formation model. ... Segmented morphable model A 3DMM constructed from m face scans, can make use of m − 1 principal components for face modelling. ...doi:10.1109/tpami.2012.206 pmid:23520253 fatcat:34x6ffbpkvdm3cqarqzjbk254u
First, I present a new method for training gaze estimation systems that use machine learning: learning-by-synthesis using 3D head scans and photorealistic rendering. ... Gaze is used for a wide range of applications including market research, usability studies, and gaze-based interfaces. Traditional equipment uses special hardware. ... These are encoded as 4×4 homogenous transformation matrices T and R, so model-to-world transform M face = TR. ...doi:10.17863/cam.13838 fatcat:epnwlenx5fgqpppifexnuwae6e
Other appearance-based methods could be used for initialization as well [Tompson et al., 2014] . ... We quantitatively and qualitatively compare the performance of our algorithm to recent appearance-based and model-based techniques (see Section 2.5). ... equivalent to the update of the IEIF from Table 7 for measurement z n = d n . ...doi:10.5075/epfl-thesis-8573 fatcat:jdpz4q4vabhurdfpc6os745rxi
