A telemedicine system with dynamic imaging, comprising:
- a local control system disposed at a first location and a central control system disposed at a remote site, said remote site being at a second location, said local control system being operatively coupled to said central control system by means of a computer network;
- said local control system including a first computing device with a first processor, a local control module, and a dynamic imaging system;
- said central control system including a second computing device with a second processor and a remote control module;
- said dynamic imaging system including an imaging device operatively coupled to said first computing device, said imaging device configured to capture images of a body portion of a patient over a predetermined duration of time so that a displacement of said body portion of said patient is capable of being tracked during said predetermined duration of time, said captured images including an initial captured image containing first image data that is produced without requesting said patient to perform any task, and said captured images further including a subsequent captured image containing second image data that is produced as a result of said patient being instructed to perform a task that induces one or more detectable physical and physiological changes in said body portion of said patient, said first computing device being programmed to determine said displacement of said body portion of said patient over said predetermined duration of time using said captured images, and to compare said displacement of said body portion of said patient over said predetermined duration of time to a reference displacement of said body portion of said patient acquired prior to said displacement so that a plurality of induced physical and physiological dynamic changes in said body portion of said patient are capable of being assessed for the purpose of identifying said patient or evaluating physiological changes in said body portion, and said first computing device being further programmed to compare using a subtraction algorithm said plurality of induced physical and physiological dynamic changes to said body portion of said patient captured by said imaging device at a first time to said plurality of induced physical and physiological dynamic changes to said body portion of said patient captured by said imaging device at a second subsequent time, and to determine if said plurality of induced physical and physiological dynamic changes captured by said imaging device at said first time substantially matches said plurality of induced physical and physiological dynamic changes to said body portion of said patient captured by said imaging device at said second subsequent time so as to verify the identity of said patient;
- wherein the body portion is a face and the subtraction algorithm eliminates unchanged parts of the face, while maintaining changed parts of the face to enhance the processing speed.
