Compressed change vector analysis
WebIf we consider the compressed parameters of each coding format, we can nd a relation to the ones used for the GSM AMR case. Obviously the numbe r of parameters and their bit size change from coder to coder. However, as explained in section 3, we can divide the whole set of compressed fea-turesinthreemaingroups,witheachgroupcontainingthepa- Webonly change-relevant features are retained [3]. C2VA method [4] i.e. Compressed change vector analysis which is spectrum-based and jointly analyze spectral-special change information (change vector feature) according to the morphological analysis. This method is used to detect the change in images.
