The models shown in these tutorials illustrate features of the SectorAnalysisToolbox software. 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.

Using the SectorAnalysisToolbox ' to analyse the shapes of cell clones'

1 Analysing 2D shapes of cell clones

How to use the tutorial. First download and install the SectorAnalysisToolbox . A zip file containing the project (Leaf growth) should be loaded. Then, from Matlab, change directory into the project and launch the SectorAnalysisToolbox

The process of analysing a set of images is:-

  1. 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.
  2. 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.
  3. 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.
  4. Generate the shape model using principal component analysis (PCA)
  5. View the result by varying each important component in turn. We call this walking the shape model. This movie shows a walk.
