Measurement of pupillary light reflex features through RGB-HSV color mapping

Measurement of pupillary light reflex features through RGB-HSV color mapping Biomed Eng Lett (2015) 5:29-32 DOI 10.1007/s13534-015-0178-y ORIGINAL ARTICLE Measurement of Pupillary Light Reflex Features through RGB-HSV Color Mapping Seong Yong Moon, Jeong Pyo Lee, Jin Ho Bae and Tae Soo Lee Received: 25 December 2014 / Revised: 19 March 2015 / Accepted: 20 March 2015 © The Korean Society of Medical & Biological Engineering and Springer 2015 Abstract Keywords Pupillary light reflex, Smartphone, Color mapping, Purpose The pupillary light reflex (PLR) test is the method MATLAB of examining the immediate reaction of the pupil by light stimuli, and the dysfunctions in autonomic nervous system can be evaluated quickly and easily through this method.
