log

Determine whether LoG features are computed or not.

phase

Determine whether local phase features are computed or not.

image_type

Modality of images supplied. Determines how the image is loaded. Mandatory to supply by user. Should be one of the valid quantitative modalities [‘CT’, ‘PET’, ‘Thermography’, ‘ADC’, ‘MG’] or qualitative modalities [‘MRI’, ‘MR’, ‘DWI’, ‘US’].

extraction_mode

Determine how to extract the features: 2D if your masks and/or images have only one 2D slice, 3D for tru 3D images, 2.5D for 3D images but in a slice-by-slice stacked 2D manner. The latter is recommended when the slice thickness is much larger (>2) than the pixel spacing.
