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 appears.

  

• 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 appears.

  

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

  

• Statistics: When you select a node in the wavelet packet tree, the Statistics tool appears 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.
