The "art of the smile" lies in the clinician's ability to recognize the positive elements of beauty in each patient and then create a strategy to enhance the attributes that fall outside the parameters of the prevailing esthetic concept. New technologies have enhanced our ability to see our patients more dynamically and facilitated the quantification and communication of newer concepts of funct...

The mysterious smile of the famed portrait ‘The Mona Lisa’ has confused both art historians and researchers for many years. The nature of the model’s enigmatic smile has been explained as the smile of a new, joyous mother, Lisa Gherardini, who had developed Bell’s palsy during her recent pregnancy. Bell palsy which is acute in onset, unilateral, and is considered to be idiopathic is the most co...

PURPOSE To compare the objective and subjective quality of vision after femtosecond laser-assisted small incision lenticule extraction (SMILE) and laser-assisted subepithelial keratomileusis (LASEK) for mild to moderate myopia. METHODS This prospective, comparative study included 65 eyes of 33 patients in the SMILE group, with a mean spherical equivalent (SE) of -4.16 ± 0.82 diopters, and 50 ...

INTRODUCTION Tooth display and lip position in smiling and speech are important esthetic aspects in orthodontics and dentofacial surgery. The spontaneous smile and speech are considered valuable diagnostic criteria in addition to the posed social smile. A method was developed to measure tooth display in both smile types and speech. METHODS The faces of 20 subjects were individually filmed. Sp...

Smile detection from unconstrained facial images is a specialized and challenging problem. As one of the most informative expressions, smiles convey basic underlying emotions, such as happiness and satisfaction, which lead to multiple applications, e.g., human behavior analysis and interactive controlling. Compared to the size of databases for face recognition, far less labeled data is availabl...

This paper introduces a parameterization of the normal mixture diffusion (NMD) local volatility model that captures only a short-term smile effect, and then extends the model so that it also captures a long-term smile effect. We focus on the binomial’ NMD parameterization, socalled because it is based on simple and intuitive assumptions that imply the mixing law for the normal mixture log price...

Satellite hyperspectral imaging sensors suffer from ‘’smile’’ and ‘’keystone’’ properties, which appear as distortions of spectrum images. The smile property is a center wavelength shift and the keystone property is a band-to-band misregistration. These distortions degrade the spectrum information and reduce classification accuracies. Furthermore, these properties may change after the launch. T...
