Abstract
In hyperspectral imaging, surface reflections and height differences within tissue samples add variations to spectra which are not related to tissue composition. To improve diagnostic accuracy, several pre-processing techniques are used to reduce these variations. However, currently a framework is lacking to choose an optimal pre-processing algorithm technique for a clinical application. We identified 8 pre-processing algorithms and investigated on synthetic data how well each algorithm reduces variations related to surface reflections and height differences and keeps variations between spectra related to differences in tissue optical properties. We demonstrate the use of our framework on colon and breast cancer tissue.
