Eeg Compression Using Wavelet Based Ebcot Algorithm
نویسندگان
چکیده
Electroencephalogram (EEG) is a common technique used to monitor the electrical activities of the human brain. In some applications, EEG is recorded for a long time. Since it is time consuming to analyze this EEG, further processing requires a lossless compression of this long term EEG. This paper addresses effective compression of EEG using EBCOT algorithm. EBCOT is an advance technique for image compression, but no work is reported on the compression of EEG using this EBCOT encoder. The performance measure used here is compression ratio.

Protecting EBCOT Encoding System for JPEG2000
Embedded Block Coding with Optimal Truncation (EBCOT) is an entropy coding algorithm adopted by JPEG2000 still image compression standard. It is a quadtree encoding method representing a fault tolerance design challenge. EBCOT operates on independently coded blocks, and is therefore more robust to channel errors than many other wavelet based schemes. However, computer-induced errors can still d...

Embedded image coding in wavelet domain has drawn a lot of attention. Among noteworthy algorithms is the embedded block coding with optimized truncation (EBCOT) algorithm, which has been adopted by the JPEG2000 standard. EBCOT is a two-tier algorithm. Tier-1 is composed of bit-plane coding followed by entropy coding. Tier-2 performs the so-called post compression rate distortion optimization (P...

The embedded block coding with optimized truncation (EBCOT) algorithm has been adopted by the JPEG2000 standard. In which, the post compression rate distortion (PCRD)optimization needs a large memory space to store all the code streams of code blocks; however, code blocks of less importance might not be used for the optimal decoded image at a bit rate. To avoid waste of computational power and ...
