Facial age estimation is one of the unsolved challenging issues in automatic face perception. Previous studies usually formulated it as a classification problem, where each age is regarded as a class, or a regression problem where the age is regarded as a variable spanning in a real-valued interval. In this paper, we propose to formulate this task as an ordinal regression problem. On one hand, ...

The ability to recognize an unfamiliar individual on the basis of prior exposure to a photograph is notoriously poor and prone to errors, but recognition accuracy is improved when multiple photographs are available. In applied situations, when only limited real images are available (e.g., from a mugshot or CCTV image), the generation of new images might provide a technological prosthesis for ot...

duane’s retraction syndrome (drs) type i is often associated with esotropia (et) and face turn in those with fusion. this study was designed to delineate the quantitative relationship between the angles of eye deviation with that of face turn. ten patients with drs type i with et and face turn toward the deviated eye, who had central fixation, were chosen. esodeviation was measured by alternate...

in order to compare sampling efficiencies of total and inhalable dust methods, three airborne dust sampling systems , 7-hole sampler , close and open face filter cassette were compared side-by-side , as stationary and for the personal samplers , in a wood working industry to evaluate their relative efficiency. a total of 162 samples were collected. the study of particle size distribution by cas...
