Wavelet lossless compression of ultraspectral sounder data

Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005. IGARSS '05., 2005
This paper provides a study concerning the suitability of well-known image coding techniques originally devised for lossy compression of still natural images when applied to lossless compression of ultraspectral sounder data. An ultraspectral sounder generates an unprecedented amount of 3D data, consisting of two spatial and one spectral dimensions ...

Lossless and Lossy Data Compression

1997
Data compression (or source coding) is the process of creating binary representations of data which require less storage space than the original data [7, 14, 15]. Lossless compression is used where perfect reproduction is required while lossy compression is used where perfect reproduction is not possible or requires too many bits.

Lossless audio data compression

2007
Lossless audio compression is a rapidly developing field with a strict stipulation: the decompressed sample information must match the original audio data. A common strategy applied by modern compression systems is a "prediction/residual " structure. This strategy generates a series of estimates for audio samples and applies coding schemes to encode ...

Lossless compression algorithm for high entropy data

Proceedings of the 4th international conference conference on Computer systems and technologies e-Learning - CompSysTech '03, 2003
There is a defined class of data sequences that are practically incompressible known algorithms. For the decision of this problem the lossless recursive algorithm offered. The algorithm realizes coding with two-part code words code words.

Lossless Satellite Data Compression

2013
Satellite sensors produce enormous data volumes, especially hyperspectral sensors that acquire over hundreds of images of narrow-wavelength bands and produce an image cube. Thus, a lot of effort has been made to study moreefficient ways to compress satellite images or image cubes. Compression techniques can be classified into three types: 1.
