Detailed Description

This is the class for Ventura fusion.

Author:

Emiliano F. Castejon <castejon@dpi.inpe.br>

Note:

The required parameters are:

Parameters:

reference_raster	( TePDITypes::TePDIRasterPtrType ) - Reference raster ( higher quality ).
lowres_raster	( TePDITypes::TePDIRasterPtrType ) - Low resolution raster ( will be improved ).
output_raster	( TePDITypes::TePDIRasterPtrType ) - Output raster.
reference_raster_band	( int ) - The band to process for reference_raster.
lowres_raster_band	( int ) - The band to process for lowres_raster.

Note:

The following parameters are optional, and will be used if present:

Parameters:

filters_scale	( double ) - The wavelet filters scale.
a_filter_l	( std::vector< double > ) - Wavelet Analysis filter, low pass, non normalized ( used in decomposition ).
a_filter_h	( std::vector< double > ) - Wavelet Analysis filter, high pass, non normalized ( used in decomposition ).
s_filter_l	( std::vector< double > ) - Wavelet Synthesis filter, low pass, non normalized ( used in recomposition ).
s_filter_h	( std::vector< double > ) - Wavelet Synthesis filter, high pass, non normalized ( used in recomposition ).

Note:

The reference_raster lines number must be a multiple of two multiplied by lowres_raster lines number.

The reference_raster columns number must be a multiple of two multiplied by lowres_raster columns number.

This algorithm is base on the work: Fernando N. Ventura, Leila M. G. Fonseca. Remotely Sensed Image Fusion Using The Wavelet Transform. International Symposium on Remote Sensing of Environment. Buenos Aires, Argentina. 2002.

parameters

)

const [virtual]

Checks if the supplied parameters fits the requirements of each PDI algorithm implementation.

Note:

Error log messages must be generated. No exceptions generated.

Parameters:

parameters

The parameters to be checked.

Returns:

true if the parameters are OK. false if not.

Implements TePDIAlgorithm.

bool TePDIVenturaFusion::RunImplementation

(

)

[protected, virtual]
