An Improved Integer Transform Combining with an Irregular Block Partition

An Improved Integer Transform Combining with an Irregular Block Partition

After conducting deep research on all existing reversible data hiding (RDH) methods based on Alattar’s integer transform, we discover that the frequently-used method in obtaining the difference value list of an image block may lead to high embedding distortion. To this end, we propose an i...
