A method for processing IR spectra, e.g. of drilling fluids or cement slurries, to achieve data compression while retaining important features, comprises the following steps: generate spectrum, obtain autocorrelation sequence for spectrum, select a desired order for an auto regressive model, calculate auto regressive coefficient from the autocorrelation sequence and the selected order so as to construct an autoregressive model, calculate the poles of the autoregressive model, and solve the characteristic equation. <IMAGE> |
