System and method for volatile organic compound detection

A system for identifying an analyte based on the presence of at least one volatile organic compound (“VOC”) in the analyte, the system in communication with an image acquisition device, the system comprising one or more processors in communication with a memory, the one or more processors configured to execute:

• an image processing module to:
• receive image data from a sensor array on the image acquisition device after the sensor array has been exposed to the analyte, the sensor array comprising at least one sensor configured to respond to the presence of the at least one VOC in the analyte;
• and
• process the image data to derive one or more input image features;
• and
• a classification module to, using a trained machine learning classification technique, classify the analyte based on the one or more input image features, the machine learning classification technique trained using one or more reference images of known analytes.
