1. A method for monitoring, testing, and/or improving cognitive abilities of a subject, comprising the steps of:
a. recording a video of the face and eyes of a subject with an image acquisition device;
b. detecting a pupil using image processing algorithms;
c. extracting eye markers from the pupil detected in said video; and
d. analyzing said extracted eye markers and deriving insights regarding trends in said subject's cognitive state;
wherein said steps of detecting the pupil and extracting eye markers from said video comprise the steps of:
I. detecting a face, followed by an eye and an eye region of the image;
II. detecting an iris by receiving as an input said eye region of said detected image, and providing as an output an iris center and radius; and
III. detecting and localizing the pupil by receiving as an input said detected iris center and radius and returning a radius of the pupil as output.
