Abstract:
1. A method for object identification and tracking, the method comprising: receiving a video comprising a plurality of image frames obtained using an imaging sensor operating in a first mode with high spatial resolution and high frame rate for object tracking; identifying at least one an area of interest in said video sequence and switching said imaging sensor to operate in a second mode with higher spectral resolution for material analysis; communicating a location of said area of interest to a spectral sensor; capturing, by said spectral sensor, a spectral image comprising different spectral planes of said area of interest, each of said spectral planes have pixel locations corresponding to a reflectance at a wavelength band of interest; analyzing pixel values in said spectral image to identify a material comprising at least one object in said area of interest, said analyzing comprising determining a classification for each pixel location in said spectral image based upon a pixel's intensity value cross-referenced against spectral characteristics of known materials in a materials spectral database; cross-referencing said identified material of said object with a list of materials of interest; and in response to said identified material matching any of said list of materials of interest, performing at least one of: continuously tracking said object using said imaging sensor until the occurrence of a terminating event, and initiating an alert.
