No eye for ears

No eye for ears

A 50-year-old man was seen for chronic renal failure of unknown origin. He had been diagnosed in 1981 and monitored continuously while his renal functions had deteriorated slowly; his current glomerular filtration rate was 17 ml/min. On this occasion, he was seen by a new doctor who observed that he was hard of hearing. The day was unusually bright and sunny; hence lateral cervical scars, 3 cm ...

Otoplasty for prominent ears deformity.

OBJECTIVE Prominent ears are a common congenital deformity of the external ear, derived from a combination of defects in the antihelix and concha. The majority of cases are treated surgically, but one of major difficulties associated with otoplasty regards the achievement of lasting aesthetic results. With the present study we propose an effective combination of four surgical techniques of cart...

Using Ears for Human Identification

Biometrics includes the study of automatic methods for distinguishing human beings based on physical or behavioral traits. The problem of finding good biometric features and recognition methods has been researched extensively in recent years. Our research considers the use of ears as a biometric for human recognition. Researchers have not considered this biometric as much as others, which inclu...

No-reference Quality Metrics for Eye Fundus Imaging

This paper presents a comparative study on the use of noreference quality metrics for eye fundus imaging. We center on autofocusing and quality assessment as key applications for the correct operation of a fundus imaging system. Four state-of-the-art no-reference metrics were selected for the study. From these, a metric based of Rényi anisotropy yielded the best performance in both auto-focusin...
