LeafAnalyser
LeafAnalyser
The image processing screen is split into quadrants. The top left is the full image currently loaded. The top right is the current leaf being processed. The bottom left is the image histogram and corresponding threshold level. The bottom right contains the parameters for the output data.
The data analysis screen allows the loading of text files (generated by the image processing section), groups to be created and Principal Component Analysis to be performed. Interactive graphs can then be viewed by clicking on the buttons at the bottom.
An example of the 2D graphing capabilities of LeafAnalyser. It displays a scatter graph of all leaf data plus ellipses indicating the mean and standard deviations of each group (defined in the data analysis screen).
An example of the 3D graphing capabilities of LeafAnalyser. As with the 2D graphs, a scatter graph of leaf data can be shown and/or ellipsoids representing the mean and standard deviations of each group. The graph is rendered in OpenGL and can be both rotated and zoomed.
A 3D graph that has been zoomed in and is only rendering the scatter data.
Another 3D graph where each node of each group is represented by an ellipsoid. This allows movements through PC space represented by changes at each node to be visualised.
LeafAnalyser is capable of generating graphs that show the contribution of each PC independently.
