Detailed Description
Base Filter to perform fusion of low resolution and high resolution images.
If the low resolution image has multiple samples per pixel, the data values should be rescaled or contrast enhanced to similar ranges across all bands to avoid undesirable color shifting, especially for the HIS and HBS methods. The resulting image will have the same dimensions as the high resolution image and the same pixel properties as the low resolution image. At present the two source images are assumed to have identical geographic extent and projection (eg, one will match the other with simple zooming).

-
pImageHighRes Pointer to high-resolution image pImageLowRes Pointer to low-resolution image TakeOwnership Filter takes ownership of previous stages and will delete when needed
Member Function Documentation
| virtual ERRVALUE SPATMOD::IMAGE::FILTER_FUSION::v_Initialize | ( | ) | [protected, virtual] |
Initialize stage before insertion into pipeline.
Must do the following (in order), checking for error after each call. Validate all class-specific settings. Open any data sources/files if required. Call v_Initialize() on base class (if not private in base). Call SetAllProperties OR call SetPixelProperties(), SetTotalDimensions(), and SetTransToCRS(). Optionally call SetTileDimensions, SetPixelRange and/or other Set... methods needed. Preprocessing of source stages to determine properties may be done here or the first time v_PullBegin is called if does not affect base image properties.
Implements SPATMOD::IMAGE::STAGE.
| virtual ERRVALUE SPATMOD::IMAGE::FILTER_FUSION::v_PullBegin | ( | const SECTION_ITERATOR & | iterator | ) | [protected, virtual] |
Begin pull of a specific section.
Default implementation calls PullBegin() for earlier stages in pipeline. If derived class overrides it must either call the base v_PullBegin() with either the same iterator on one that has been suitably adjusted based on the filter's behavior, or call PullBegin() for all earlier stages directly. This would typically be done before doing any filter-specific processing.
Reimplemented from SPATMOD::IMAGE::FILTER.
