Detection theory first became famous because of its radar application
success, but electrical engineers have since used it in
a variety of other problems ranging from detection of failure
in a machine or device, to detection of blood vessels in
stereographic images of the brain, to detection of targets
in automatic driving.
In geophysical research it has already been used
for parameter estimation.
For all its impressive applications detection theory
is established on a few simple ideas from hypothesis testing.
