With the development of computer graphic techniques and smaller visual difference between photographic images (PG) and computer graphics (CG), splicing of computer graphics and photographic is becoming more common, which causes the need for automatically distinguishing computer generated images from real photographs. Based on several visual features that derived from color, texture and shape fe...

BACKGROUND To assess the ability of fluorescence imaging to detect a dose response relationship between fluorosis severity and different levels of fluoride in water supplies compared to remote photographic scoring in selected populations participating in an observational, epidemiological survey in Chiang Mai, Thailand. METHODS Subjects were male and female lifetime residents aged 8-13 years. ...

BACKGROUND Redundant facial and neck skin is a major feature of aging and historically has been corrected surgically. Recently, monopolar radiofrequency application has been introduced for nonablative tissue tightening of skin by volumetric heating of the deep dermis. It has been able to improve neck and cheek laxity and periorbital rhytides and to elevate eyebrows. However, questions remain as...

We explore two recent methods for measuring the Modeling Transfer Function of a printing system. We investigate the dependency on the amplitude when using the sinusoidal patches of the method proposed in and show that for too small amplitudes the measurement of the MTF is not trustworthy. For the method proposed in we discuss the underlying theory and in particular the use of a significance tes...
