| ROIScaler | This class deals with the ROI functionality. The ROI method is the Maxshift method. The ROIScaler works by scaling the quantized wavelet coefficients that do not affect the ROI (i.e background coefficients) so that these samples get a lower significance than the ROI ones. By scaling the coefficients sufficiently, the ROI coefficients can be recognized by their amplitude alone and no ROI mask needs to be generated at the decoder side. The source module must be a quantizer and code-block's data is exchange with thanks to CBlkWTData instances. |
