Processing multiple Videos in parallel

I am building a Matlab application that takes as input videos from multiple sources, each corresponding to a patient. The patients' faces are detected and tracked in real time and each frame is processed to output mean values for R, G, and B channels. The videos are run for a fixed number of frames determined beforehand. When this is done, the R,G, and B signals are used to compute the heart rates for patients. So for a single patient, the code looks something like the pseudocode shown below. This is for one patient. What I would like to do is do this for multiple patients being monitored simultaneously. Is there a way to run this code in parallel for multiple videos being acquired in real time?

While frameCount<No_of_Frames_to_run
take snapshot
detect face
Output mean value for R,G and B channel in face
end

**process R,G,B signals to output heart rate**
