1. A method for measuring of arterial pulse comprising steps of:

  • obtaining a sequence of thermal infrared images from a subject, wherein each said thermal infrared image is obtained without skin contact with said subject;

    performing a first analysis of said sequence of obtained thermal infrared images to detect at least one region of interest for further analysis;

    performing a second analysis of said sequence of obtained thermal infrared images to track said at least one region of interest, wherein said second analysis includes detecting a corresponding spatial location of each of said at least one region of interest;

    performing a third analysis of said at least one region of interest to select at least one configuration of a region of measurement of arterial pulse within said corresponding region of interest; and

    determining at least one arterial pulse waveform from said selected configuration of region of measurement.
