Abstract: A method and system for detection and alerting of a known condition within an environment. The systems and methods obtain a plurality of reference images from a plurality of samples under known conditions, provide each of the plurality of reference images to an image recognition algorithm and generate a historical database of reference images to be used in real-time. The system can obtain real-time samples, render spectral ages of the sample's composition, and use the image recognition algorithm to compare the overall shape of the image to the overall shapes in the reference images to determine if they match to within a threshold value. Upon a positive determination that the images match within a threshold value, an alert can be sent to the supervisor of an environment to warn them of the onset of a known condition. In some examples, counter-measures can be employed to alleviate certain known conditions.
