1 How to analyse 2D shapes using the Graphical User Interface

The process of analysing a set of images is:-

Create a new project. AAMToolbox project names are automatically prefaced with PRJ_. They have a particular directory structure and the images to be analysed need to be copied into the subdirectory called Cropped. It is best if they are all the same size. Tutorial on making a new project. 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. Tutorial on point model template. To digitise each image, 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. Tutorial on point model editor. Generate the shape model using principal component analysis (PCA) 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. Tutorial on viewing statistical model. Best fit point model using only the principle components. Tutorial on fitting a model to a particular image.
