__NOTOC__
The models shown in these tutorials illustrate features of the AAMToolbox software. They are not designed to understand the shape and appearance modelling which is better done from the published literature [http://www.computer.org/portal/web/csdl/doi/10.1109/34.982900 for example].<br>
Viewing these pages. Some versions of ''Firefox'' and ''Explorer'' do not create satisfactory prints even though you can view the pages with no problems. ''Chrome'' does appear to produce good printouts.
=Three ways to use ''AAMToolbox ''=
1) [[AAMToolbox Documentation#2 Creating shape models in 2D| '''Analysing shapes.''']] i.e. the arrangement of points around a shape<br><br>
2) [[AAMToolbox Documentation#1 Creating shape models in 2D| '''Comparing shapes from samples of different groups''']] for example, comparing faces from different cartoon characters<br><br>
3) [[AAMToolbox Documentation#3 Analysing both shape and appearance in 2D|'''Analysing shape and appearance.''']] In addition to the points around a shape, analyse the appearance (grey scale or colour) within the shape.<br><br>
4) [[AAMToolbox Documentation#4 Creating shape models in 3D|'''Analysing 3D shapes''']]

'''How to use the tutorial.''' First [[AAMToolbox Download|download and install the AAMToolbox]]. A zip file containing the project (''PRJ_CartoonFaces'') is available [http://cmpdartsvr1.cmp.uea.ac.uk/downloads/software/PRJ_CartoonFaces.zip here]. Download and unzip into a directory. Then, from Matlab, change directory into the project
cd PRJ_CartoonFaces
This project contains
<gallery caption="a set of faces" widths="60px" heights="100px" perrow="8" border="0">

</gallery>
The process of analysing a set of images is:-
{| border="0" cellpadding="5" cellspacing="3"
|- valign="top"
|width="700pt"|
#Create a point model template. Points are placed around the object of interest, i.e. around a face or leaf. The set of points constitute the '''point model'''.  Every image will be marked up in the same way.
#*[[AAMToolbox template|Tutorial on point model template.]]
#Move the points to the corresponding positions in each image in turn. The positions must'' '''correspond''' to the same material points'' in each image, i.e. the tip of the leaf, the corner of an eye, or halfway along a line between the two ends of the mouth.
#*[[AAMToolbox point model editor|Tutorial on point model editor.]]
#Generate the shape model using principal component analysis (PCA)
#*[[AAMToolbox statistical model generator|Tutorial on statistical model generator.]]
#View the result by varying each important component in turn. We call this ''walking'' the shape model. This movie shows a walk.
