List the factors that comprise the image formation model. Describe each briefly.
Image Formation Model consists of following
consists of
shapes:

. (e.g. ventricles, putamen,
hippocampus, ...)
can be any spatial
transformation within a specified set. The set can include
non-linear warps with arbitrarily large number of Degrees Of
Freedom. This transformation applies to all of the shapes,

are intensity scaling parameters
and
generates the
th basis image of a shape ..
is a spatially uncorrelated
Gaussian noise process with

.Note that all images (
,
,
, etc) are treated as vectors of
length
, where
is the number of voxels in the
image.
