Abstract
Described herein is an apparatus and method of detecting bruxism. The method includes the steps of: capturing a video of a subject, performing by circuitry included in the apparatus, spatial filtering of each image frame included in the captured video. Further, the method includes generating by circuitry, a filtered image by temporally filtering the spatially filtered image frames, the temporally filtered image including data belonging in a first frequency range, and wherein a subset of data is associated with a predetermined color variation to indicate presence of bruxism in the subject.
