1. A method for remote physical therapy and assessment, the method executed by at least one processor, comprising:
capturing, via one or more sensors, frames of a patient undertaking a prescribed activity;
processing the captured frames of the patient undertaking the prescribed activity;
the capturing of the frames being undertaken by a left sensor and a right sensor; and
the processing of the captured frames comprising:
transmitting the captured frames to an internal depth image processor, wherein the captured frames consist of pixel data of one or more captured scenes;
calculating, by the internal depth image processor, a depth of each pixel, to produce depth pixel values;
processing, by the internal depth image processor, the depth pixel values to create a depth frame;
combining, by the internal depth image processor, the depth frames into a depth video stream;
applying a point cloud over the depth video stream; and
estimating position and orientation of the patient's body joint centers.
