A method of decontaminating a surface of a material includes obtaining training data including thermographic images of a test surface on which a liquid with a decontamination agent is deposited, the thermographic images including intensity values that describe radiation emitted across the test surface over time. The method includes accessing a parametric model of the radiation emitted as a function of time, and applying a spatial regularization to the parametric model in which parameters of the parametric model are made functions of location across the test surface of the material. The parametric model with the spatial regularization is fit to the training data to produce a fitted parametric model. And the fitted parametric model is deployed to predict the radiation emitted across a working surface on which the liquid is deposited, and decontamination of the working surface is determinable from the radiation emitted as predicted.
