Superimposition of serial 3-dimensional facial photographs to assess changes over time: A systematic review

Jonathan Johannes Wampfler et al.

Summary: This study systematically summarizes the current evidence on superimposition methods of serial 3-dimensional facial photographs. The limited available evidence suggests that surface-based registration is superior to landmark-based registration. However, there is high heterogeneity among studies and further research is required to improve accuracy and precision.

A comparison between stereophotogrammetry and smartphone structured light technology for three-dimensional face scanning

Giorgio D'Ettorre et al.

Summary: This study compared the performance of a 3D facial scanning system with two different smartphone applications supporting the TrueDepth technology. The results showed that the smartphone applications had longer image acquisition and processing times, and larger surface deviations compared to the reference system. However, these applications demonstrated advantages in terms of cost and portability.

Accuracy of RGB-D camera-based and stereophotogrammetric facial scanners: a comparative study

Fangwei Pan et al.

Summary: This study aims to evaluate and compare the accuracy and inter-operator reliability of a low-cost RGB-D camera-based facial scanner with a stereophotogrammetry facial scanner, and explores the possibility of the former as a clinical substitute for the latter.

Accuracy of 3-dimensional stereophotogrammetry: Comparison of the 3dMD and Bellus3D facial scanning systems with one another and with direct anthropometry

Jialing Liu et al.

Summary: The study compared the accuracy of 3D digital facial photographs taken by Bellus3D Face Camera Pro and 3dMDface system with direct anthropometry. Results showed that 3dMD was equivalent to DA in most measurements, while Bellus3D was mostly equivalent to 3dMD and DA in some measurements. The trueness of both scanners was clinically acceptable, with good scanning repeatability and excellent interobserver agreement.

Three-Dimensional Quantification of Facial Asymmetry in Children with Positional Cranial Deformity

Andreas Naros et al.

Summary: A new three-dimensional photogrammetry quantification method was established to evaluate facial asymmetry in positional plagiocephaly, revealing significant asymmetry in nearly all spatial directions and facial regions due to positional plagiocephaly. Helmet therapy led to a significant reduction in facial asymmetry, but complete elimination was not achieved.

Smile dimensions affect self-perceived smile attractiveness

Simone Horn et al.

Summary: The study demonstrates a significant correlation between smile width and self-assessed smile attractiveness, particularly stronger in females. Smiling increases socially perceived attractiveness and is considered a signal of trustworthiness and intelligence.

Atlas of voluntary facial muscle activation: Visualization of surface electromyographic activities of facial muscles during mimic exercises

Nikolaus P. Schumann et al.

Summary: Complex facial muscle movements are crucial for motoric and emotional functions, and are difficult to detect without a standard tool like sEMG. A visual atlas has been developed to show which facial muscles are activated during specific tasks, aiding in the design of sEMG experiments and research in speech therapy and orofacial rehabilitation.

Valid 3D surface superimposition references to assess facial changes during growth

Simeon T. Haener et al.

Summary: Recent introduction of 3D facial photography offers a risk-free alternative to traditional 2D image assessment. A study found that a small rectangular area on the forehead plus an area including the middle part of the nose and the lower wall of the orbital foramen provided comparable results to a standard technique for superimposing serial 3D facial images.
