Webmultiplicative scatter correction (MSC). The details about these spectral transformations can be found in a review by Rinnan et al. [34]. All the transformations were implemented with MATLAB version R2008b software (The Math Works, Natick, MA, USA). The eight pre-processing methods were used WebThe spectra were transformed by multiplicative scatter correction (MSC). Principal component regression (PCR) was performed, on both scatter-corrected and uncorrected spectra. Calibration and prediction were performed for four food constituents: protein, fat, water, and carbohydrates. bitlabs shaders https://ghitamusic.com
