Improved Baseline Correction Method Based on Polynomial Fitting for Raman Spectroscopy
Photonic Sensors, 2018 Raman spectrum, as a kind of scattering spectrum, has been widely used in many fields because it can characterize the special properties of materials. However, Raman signal is so weak that the noise distorts the real signals seriously. Polynomial fitting

Lossy Compression using Adaptive Polynomial Image Encoding
Advances in Electrical and Computer Engineering, 2021 In this paper, an efficient lossy compression approach using adaptive-block polynomial curve-fitting encoding is proposed. The main idea of polynomial curve fitting is to reduce the number of data elements in an image block to a few coefficients.

Polynomial fit of interferograms [PDF]
Applied Optics, 1982 Polynomial fit of interferograms is analyzed quantitatively. The errors from polynomial fit, such as fit error, digitization error, roundoff error, and finite sampling error, are explained. The advantage of using orthonormal polynomials are presented.
