Claim 8:
9. The method of claim 1, further comprising, prior to step B), steps of:
I) in response to receipt of a plurality of training color images, performing a transformation operation on the training color images using the spectral transformation matrix so as to obtain a plurality of transformed training images;
J) performing a dimension reduction operation on the transformed training images, so as to obtain a plurality of dimension-reduced datasets associated with the transformed training images, respectively; and
K) supplying the dimension-reduced datasets and a plurality of severity tags that correspond with the training color images, respectively, and that indicate various degrees of air pollution as inputs to a machine learning algorithm to perform a training operation, so as to construct the estimating model.
