Abstract :
To process or introduce editing effects on JPEG2000 images, we propose techniques applying these operations in the compressed domain. Our approach exploits the properties of the wavelet transform and the rich bitstream syntax of the JPEG2000 standard. The suggested techniques provide significant speed-ups compared to the conventional methods based on spatial domain processing of the decoded images.
