This covers both basic Theory and NPAC projects with examples
|
|
Wavelet compression activity: goals
|
|
Compression of still images:
|
|
improving quality for fixed bitrate
|
|
decreasing encoding time (currently encoding still image takes 2 seconds on SGI Challenge; similar problem exists for DCT like H.263 based systems - currently no real-time encoding exists in software)
|
|
parallelizing: decomposition, quantization and arithmetic coding (important in view of emergence of multiprocessor PentiumPro systems)
|
|
Compression of video:
|
|
we verified that motion estimation in wavelet space does not work
|
|
plan: hybrid video method
|
|
Web and other functionalities:
|
|
progressive still image plug-in (implemented)
|
|
in progress - zoom, local window, chroma key
|
|
plans: transparency, pre- and post-processing, access key file protection, error recovery
