Description
This program, interestcube, uses an interest operator to quantify how interesting each point of the input cube is. The size of the output cube matches the input cube. Each DN value of the output cube represents the quality of interest that corresponds to points in the input cube. The values of the output cube represent the quality of interest of each corresponding point in the input cube.
The user must select an interest operator (algorithm) from one of the following: 1) Förstner, 2) Gradient 3) Moravec and 4) Standard Deviation. The operator and its required values are specified in the input PVL parameter for interestcube. This input PVL is a text file that may be copied from the Examples section of this page.
Note: Forstner operator output will need to be manually stretched to see visual results, due to the wide range of values it creates.

Parameter Name:
TO The interest cube image after processing. To view a Förstner image you MUST manually stretch the image. This image has been stretched from 0 to 1.67854e-27. Keep in mind if you dont do this, the data in the cube will be valid, but will display all white in qview. |

| Sharmila Prasad | 2010-04-14 | Create a universal ground map of the input cube to be passed onto the Interest Operator to calculate the Emission Angle |
| Ian Humphrey | 2014-06-03 | Closed the open cube to prevent errors from running sequential data in GUI. Fixes #1002. |
| Makayla Shepherd | 2015-02-06 | Initialized the global variables and changed the catch in ISISMain in order to close the cube before the exception is thrown. Fixes #2124, 2125. |
| Curtis Rose | 2016-04-29 | Fixed a documentation mistake. Extraneous information was removed from a command line example. Fixes #3910. |
