Figure 3. Graphical user interface (GUI) to define parameters for pre-processing filters and radiomics maps.
(a) GUI allows user to select a filter and its associated parameters. For example, three-dimensional wavelets filter. (b) The radiomics maps and the pre-processed images can be visualized along with the original image. For example, computed tomography scan and the HLH direction Coiflet1 wavelets (1) pre-processed image.
