this paper presents a comparative study of different denoising techniques applied to functional magnetic resonance imaging (fMRI) data. The performance of these techniques was investigated using a simulated fMRI time series data with a set of predefined noise levels. The performance of these techniques was evaluated with respect to two quantitative measures; signal-to-noise ration (SNR), and shape preservation. As a result of the comparative study it has been found that denoising using Wavelet transform with reverse biorthogonal basis functions provides the best performance among all denoising techniques.
