ENVIBoundingBoxSet::RemoveBoundingBox

The RemoveBoundingBox method removes a bounding box from an ENVIBoundingBoxSet.

This method is part of ENVI Deep Learning, which requires a separate license and installation.

Example

See the example for ENVIBoundingBox.

Syntax

To remove a specific bounding box from a given class:

ENVIBoundingBoxSet.RemoveBoundingBox, CLASS=value [, BOUNDING_BOX=value] [, ERROR=value]

Or:

ENVIBoundingBoxSet.RemoveBoundingBox, CLASS=value [, INDEX=value] [, ERROR=value]

To remove all bounding boxes from a given class:

ENVIBoundingBoxSet.GetBoundingBox, CLASS=value [, /ALL] [, ERROR=value]

Arguments

None

Keywords

ALL (optional)

Set this keyword to remove all bounding boxes from a given class.

BOUNDING_BOX (optional)

Set this keyword to a [2,5] array with bounding box information to remove. The values represent X/Y pixel coordinates. The first and last entry should be the same. The array should be in this format:

[[Upper Left XY], [Upper Right XY], [Lower Right XY], [Lower Left XY], [Upper Left XY]]

Example:

  BOUNDING_BOX = [[755, 283], [768, 283], [768, 739], [755, 739], [755, 283]]

CLASS (required)

Set this keyword to an integer with the class value.

ERROR

Set this keyword to a named variable that will contain any error message issued during execution of this routine. If no error occurs, the ERROR variable will be set to a null string (''). If an error occurs and the routine is a function, then the function result will be undefined.

When this keyword is not set and an error occurs, ENVI returns to the caller and execution halts. In this case, the error message is contained within !ERROR_STATE and can be caught using IDL's CATCH routine. See IDL Help for more information on !ERROR_STATE and CATCH.

See the Manage Errors topic in ENVI Help for more information on error handling.

INDEX (optional)

Specify an integer with the index number of a specific bounding box to remove.
