Wavelet Toolbox

Node Action Functionality

The available options in the Node Action menu are:

• Visualize: When you select a node in the wavelet packet tree the corresponding signal is displayed.



• Split/Merge: If a terminal node is selected it is split, growing the wavelet packet tree. Selecting other nodes, has the behavior of merging all the nodes below it in the wavelet packet tree.



• Recons.: When you select a node in the wavelet packet tree, the corresponding reconstructed signal is displayed.



• Select On/Off: When On, you can select many nodes in the wavelet packet tree and then you can reconstruct a synthesized signal from the selected nodes using the Reconstruct button on the main window. The Off selection is used to deselect all the previous selected nodes.



• Statistics: When you select a node in the wavelet packet tree, the Statistics tool is displayed using the signal corresponding to the selected node.



• View Col. Cfs.: When active, this option removes all the colored coefficients displayed, and lets you redraw only the corresponding coefficients by selecting a node in the wavelet packet tree.
