FilterContoursOperation (GRIP API)

java.lang.Object
- edu.wpi.grip.core.operations.composite.FilterContoursOperation

All Implemented Interfaces:

Operation
```
public class FilterContoursOperation
extends java.lang.Object
implements Operation
```
An Operation that takes in a list of contours and outputs a list of any contours in the input that match all of several criteria. Right now, the user can specify a minimum area, minimum perimeter, and ranges for width and height. This is useful because running a Find Contours on a real-life image typically leads to many small undesirable contours from noise and small objects, as well as contours that do not meet the expected characteristics of the feature we're actually looking for. So, this operation can help narrow them down.
