Fast identification of JPEG 2000 images for digital cinema profiles
A method for identifying JPEG 2000 images with different coding parameters, such as DWT-filters, code-block sizes, quantization step sizes, and resolution levels, is presented. ...

Reusing the H.264/AVC deblocking filter for efficient spatio-temporal prediction in video coding
The prediction step is a very important part of hybrid video codecs for effectively compressing video sequences. While existing video codecs predict either in temporal or in spati...

Cross-spectrum and coherence function estimation using time-delayed Thomson multitapers
An idea is presented where multitapers are extracted from a known cross-spectrum and applied for estimation of the coherence function. An important property of the extracted windo...
