PART|II Multimodal Signal Processing and Modelling
from different spectral bands [10] (visible, infrared or microwave,
for example).
For both medical image analysis and remote sensing, the gain from
using images from multiple modalities comes from their complemen-
tarity. More information will be present in a combined multimodal
image than in each of the monomodal ones, provided they have
been properly aligned. This alignment is based on information that is
common to all the modalities used, redundant information.
7.2 ADVANTAGES OF MULTIMODAL ANALYSIS
Although there is such high variability in multimodal signals, general
processing methods exist which ...
