sniff gradientSniff Gradient

This tool will find the gradient of an edge or within an image that match the parameters given. It will display where these points of gradient are located on the CIF Viewer, and it will give the  number of points found on the parameters page of the tool.

Using the Sniff Gradient Tool

Left click on the tool to bring up a box that can be moved within the CIF Viewer to decide the starting point for where the gradients need to be found. The user can drag this box all around the image on the CIF viewer to find the place to begin.

Inputs

The inputs page is set up to run. Clear any items that are in the "Start box" should the default have something there (the "start" box is the bottom of the three boxes).

Parameters

This page will allow the user to set the information for the location of the gradient that they want to find.
Placing an X in the clockwise box will look for points around the edge that is clockwise. Un X-ing the box find the points that are counter clockwise on the shape/image.
Once the tool is run it will display the number of points found in the "Count" box.

The parameters to be set are these:

Gradient Size: The size of the gradient the user is looking for within the image.
Gradient Leniency: Leniency is a measure of edge/gradient steepness. The bigger the number the more likely the gradient finder will find more gradients. Units are pixels.
Gradient Minimum: The minimum degree of change within the steepness of a gradient.
Skip: The number placed here will be the number of points it skips between points displayed (this helps minimize congestion if multiple areas meet the criteria).
MaxNbPoints: This will only display up to the amount of points that are placed in this category.

The user can use the Render Style box to change the way the points appear as they display on the CIF Viewer.
