A method is proposed to detect a human iris location and size in a digital image given some point lying inside the pupil. Method is based on the construction of histogram projections of local brightness gradients, and interrelating local maxima of these histograms as probable positions of pupil and iris borders. The method has a low calculation cost.
BACKGROUND In critical care units, pupil examination is an important clinical parameter for patient monitoring. Current practice is to use a penlight to observe the pupillary light reflex. The result seems to be a subjective measurement, with low precision and reproducibility. Several quantitative pupillometer devices are now available, although their use is primarily restricted to the research...
The object of the study was to compare resting pupil diameter in darkness and light, and the pupillary darkness and light reflexes between a group of young and elderly healthy subjects. Twelve young (eight men, four women; median age 19.5 years) and 14 elderly subjects (six men, eight women; median age 69 years) participated. Pupil diameter was monitored with an infra-red television pupillomete...
