1. A system for strabismus assessment comprising:
a display module arranged to display a visual stimulus to be observed by an observer;
an image capturing module arranged to record a plurality of images of at least one eye of the observer observing the visual stimulus; and
a processing module arranged to determine an ocular misalignment condition of the observer based on the plurality of images recorded by the image capturing module;
wherein the processing module includes an AI-based processing engine;
wherein the AI-based processing engine includes a deep learning-based strabismus deviation module arranged to determine a strabismus deviation of the observer's eye; and
wherein the processing module further comprises a pupil detection and enhancement module, wherein the pupil detection and enhancement module arranged to perform an image enhancement process including one or more of iris region extraction, pupil region refining, edge detection and filtering, and ellipse fitting, so as to improve a determination of a position of pupil for strabismus assessment.
