GradientPyr

DESCRIPTION

This module acts as a front end to GradientLat and shares an executable with it. Any layer of a pyramid that contains a lattice can be extracted and the gradient of the data on that lattice is computed. The lattice at that layer is replaced with the new lattice containing the gradients.

INPUTS

Port: Pyramid In
Type: Pyramid
Constraints: 1..-layer
Constraints: 1..-baseLat
Constraints: n-D compression
Constraints: n-compression type
The input pyramid.

WIDGETS

Port: Scale
Type: Dial
A scale factor to be applied to the computed gradients.

Port: Channel
Type: Slider
If the data at the selected layer is vector, this widget selects the vector component.

Port: Layer
Type: Slider
Select the required layer. Layer 0 is the base lattice.

OUTPUTS

Port: Pyramid Out
Type: Pyramid
Constraints: 1..-layer
Constraints: 1..-baseLat
Constraints: n-D compression
Constraints: n-compression type
The new pyramid containing the replaced lattice.
