C# Class CSJ2K.j2k.wavelet.synthesis.InverseWT

This abstract class extends the WaveletTransform one with the specifics of inverse wavelet transforms.

The image can be reconstructed at different resolution levels. This is controlled by the setResLevel() method. All the image, tile and component dimensions are relative the the resolution level being used. The number of resolution levels indicates the number of wavelet recompositions that will be used, if it is equal as the number of decomposition levels then the full resolution image is reconstructed.

It is assumed in this class that all tiles and components the same reconstruction resolution level. If that where not the case the implementing class should have additional data structures to store those values for each tile. However, the 'recResLvl' member variable always contain the values applicable to the current tile, since many methods implemented here rely on them.

Méthode	Description
InverseWT ( MultiResImgData src, DecoderSpecs decSpec ) : System	Initializes this object with the given source of wavelet coefficients. It initializes the resolution level for full resolutioin reconstruction (i.e. the maximum resolution available from the 'src' source). It is assumed here that all tiles and components have the same reconstruction resolution level. If that was not the case it should be the value for the current tile of the source.
close ( ) : void	Closes the underlying file or network connection from where the image data is being read.
createInstance ( CBlkWTDataSrcDec src, DecoderSpecs decSpec ) : InverseWT	Creates an InverseWT object that works on the data type of the source, with the special additional parameters from the parameter list. Currently the parameter list is ignored since no special parameters can be specified for the inverse wavelet transform yet.

Method Details

InverseWT() public méthode

Initializes this object with the given source of wavelet coefficients. It initializes the resolution level for full resolutioin reconstruction (i.e. the maximum resolution available from the 'src' source).

It is assumed here that all tiles and components have the same reconstruction resolution level. If that was not the case it should be the value for the current tile of the source.

createInstance() public static méthode

Creates an InverseWT object that works on the data type of the source, with the special additional parameters from the parameter list. Currently the parameter list is ignored since no special parameters can be specified for the inverse wavelet transform yet.
