What are the characteristics of the LBP algorithm?
The LBP algorithm produces approximate, but very blurred permittivity images. For example, a typical image, for a dielectric tube inside a 12-electrode sensor, is shown in the first figure below. The LBP algorithm acts as a spatial filter with a lower cut-off frequency than that of the fundamental filter (as shown in the second figure below) and consequently produces sub-optimal images from a given set of input data.
