The study of growth and development of the facial profile is of interest to clinicians and researchers in the fields of pediatric dentistry, orthodontics, and craniofacial surgery, enabling diagnosis, planning, and evaluation of treatment. Until recently, craniofacial studies addressed facial growth, facial asymmetry, and gender differences by examining changes in size. However, size changes al...

Automatic analysis of facial gestures is an area of intense interest in the human-computer interaction design community. A robust way to discern facial gestures in images of faces, insensitive to scale, pose, and occlusion, is still the key research challenge in the automatic facial-expression analysis domain. A practical method recognized as the most promising one for addressing this problem i...

one of the most important goals of orthodontic treatment is to create an esthetic, well balanced facial profile. however, the components of a well-balanced iranian facial profile have not yet been established. the purpose of this study was to evaluate the anteroposterior lip position of the iranian population and to compare the perception of orthodontists, dental students and orthodontic patien...

statement of the problem: achieving a normal soft tissue facial profile is considered to be the main concern of class iii patients and the goal of most class iii treatments. purpose: the purpose of this study was to investigate the effects of facemask treatment on profile with photogrammetric method. materials and method: before (t0) and after (t1) treatment photograms of 40 class iii patients ...

3D facial data has a great potential in overcoming the problems of illumination and pose variation in face recognition. In this paper, we investigate face recognition from range data by facial profiles and surface. An efficient symmetry plane detection method for facial range data is presented to help extract facial profile. A global profile matching method is then exploited to align and compar...

BACKGROUND Proper pre-operative facial analysis that includes a thorough evaluation of both the bony and soft tissue anatomy is paramount to success in performing aesthetic surgery of the face. Ethnic variations in soft tissue profile add an important variable to pre-operative facial analysis. The aim of our study was to determine the role of ethnic variations in soft tissue facial profiles th...

A robust way to discern facial gestures in images of faces, insensitive to scale, pose, and occlusion, is still the key research challenge in the automatic facial-expression analysis domain. A practical method recognized as the most promising one for addressing this problem is through a facial-gesture analysis of multiple views of the face. Yet, current systems for automatic facial-gesture anal...

OBJECTIVE To describe the age-related changes of the soft tissue facial profile from the second to fourth decades of life. MATERIALS AND METHODS Cephalograms from the same subjects in their 20s, 30s, and 40s were analyzed. A coordinate system analysis based on stable landmarks is used. A line connecting Walker's point (W) and sphenoethmoidal (SE) created the x-axis. Walker's point was origin....

INTRODUCTION: Subjective facial analysis is a diagnostic method that provides morphological analysis of the face. Thus, the aim of the present study was to compare the facial and dental diagnoses and investigate their relationship. METHODS: This sample consisted of 151 children (7 to 13 years old), without previous orthodontic treatment, analyzed by an orthodontist. Standardized extraoral an...
