Parameter  Description  

Signal  Contains the following options:
 
Wavelet Design  Designs customized analysis filters and synthesis filters for discrete wavelet analysis and reconstruction, respectively. Contains the following options:

Parameter  Description 

File path  Specifies the file path of the 2D image you want to load. This input is available only if you select the From file option in the Data Source section. 
Image  Specifies the block diagram terminal of the 2D image you want to load. This input is available only if you select the From terminal option in the Data Source section. 
error in (no error)  Describes error conditions that occur before this node runs. 
Parameter  Description 

Reconstructed Image  Returns the reconstructed image. 
Selected Coefficients  Returns the wavelet coefficients of the frequency band(s) you select to reconstruct the 2D image. 
error out  Contains error information. This output provides standard error out functionality. 
This Express VI operates similarly to the following VIs and functions:
WA Discrete Wavelet Transform
WA Inverse Discrete Wavelet Transform
Refer to the Multiresolution Analysis  Image VI in the labview\examples\Wavelet Analysis\WAGettingStarted directory for an example of using the Multiresolution Analysis 2D Express VI.
