jj2000.j2k.roi.encoder.SubbandRectROIMask

public class SubbandRectROIMask
extends SubbandROIMask

This class describes the ROI mask for a single subband. Each object of the class contains the mask for a particular subband and also has references to the masks of the children subbands of the subband corresponding to this mask. This class describes subband masks for images containing only rectangular ROIS

Constructor Detail

SubbandRectROIMask

public SubbandRectROIMask(Subband sb,
                  int[] ulxs,
                  int[] ulys,
                  int[] lrxs,
                  int[] lrys,
                  int nr)

The constructor of the SubbandROIMask takes the dimensions of the subband as parameters. A tree of masks is generated from the subband sb. Each Subband contains the boundaries of each ROI.

Parameters:

sb - The subband corresponding to this Subband Mask

ulxs - The upper left x coordinates of the ROIs

ulys - The upper left y coordinates of the ROIs

lrxs - The lower right x coordinates of the ROIs

lrys - The lower right y coordinates of the ROIs

nr - Number of ROIs that affect this tile
