The regions of elution for each component can be similarly defined as for EFA above. There are numerous variations on fixed sized window factor analysis, such as changing the window size across die chromatogram, and the results can change... [Pg.379]

Fixed-size moving-window-evolving factor analysis (FSMW-EFA). This technique, also called window factor analysis (WFA), is based on a window of a predefined number of rows or spectra, typically from three to five, which... [Pg.209]

Some of the local-rank analysis methods, such as evolving-factor analysis (EFA) [27-29], are more process oriented and rely on the sequential evolution of the components as a function of time or any other variable in the data set, while others, such as fixed-size moving-window-evolving-factor analysis (FSMW-EFA) [30, 31], can be applied to processes and mixtures. EFA and FSMW-EFA are the two pioneering local-rank analysis methods and can still be considered the most representative and widely used. [Pg.423]

Fixed-size image window-evolving factor analysis (FSIW-EFA) is an evolution of the local rank algorithm fixed size moving window-EFA [111], particularly designed for the study of the local pixel complexity in images [112]. To do so, two main ideas are taken into account the need to divide the image into small areas to get local information and the need to preserve the 2D or 3D spatial... [Pg.83]
