## Long Description

This application builds a multi-resolution pyramid of the input image. User can specified the number of levels of the pyramid and the subsampling factor. To speed up the process, you can use the fast scheme option

## Parameters

- [param] -in <string> . Mandatory: True. Default Value: ""
- [param] -out <string> will be used to get the prefix and the extension of the images to write. Mandatory: True. Default Value: ""
- [param] -ram <int32> Available memory for processing (in MB). Mandatory: False. Default Value: "128"
- [param] -level <int32> Number of levels in the pyramid (default is 1).. Mandatory: True. Default Value: "1"
- [param] -sfactor <int32> Subsampling factor between each level of the pyramid (default is 2).. Mandatory: True. Default Value: "2"
- [param] -vfactor <float> Variance factor use in smoothing. It is multiplied by the subsampling factor of each level in the pyramid (default is 0.6).. Mandatory: True. Default Value: "0.6"
- [param] -fast <boolean> If used, this option allows speeding up computation by iteratively subsampling previous level of pyramid instead of processing the full input.. Mandatory: False. Default Value: "True"
