We refer to this hybrid run-length codes,it has the excellent advantages of high compression ratios,robust and low area overhead.

An improving on Wyle-symbol method for run length coding;

Aiming at improuing Zero\|tree coding, run length coding and human visual character were combined and utilized in this work.

So a new scheme of test data compression decompression,namely sharing-run-length code scheme(SRLCS)is presented,which is based on run length coding.

Optimization and application of connected component labeling algorithm based on run-length encoding;

Aiming at the low computation efficiency and storage insufficiency of direct-encoded raster data,a new data structure on the basis of run-length encoding has been proposed to optimize the algebraic operations.

The algorithm implemented run-length encoding through a successive scan,then proceeded to label run-length and merge the conflict objects by analyzing the connectivity with run-lengths in the above row.

An optimized EZW method using run-length coding;

Image retrieval of the block edge pattern based on run-length coding;

After the clustering characteristics of image wavelet coefficients′ significance distribution in each sub-band was analyzed,run-length coding(RLC) was introduced into SPIHT′s output stage.

This paper puts forward a method to conceal black and white image,which applies run-length code technique to realize non-damage compression to the white and black image in order for decrease the pixel modification to the covering carrier.

The ideas of the improved algorithm mainly include: The lowest frequency subband is coded without loss;the reverse Morton scan order is adopted;and running length coding is carried out of symbol bitstream to reduce the redundancy among zerotrees.

The algorithm combines embedded zero-tree multi-wavelet coding and running length coding is used for the high-frequency coefficients and Huffman lossless compression is employed for the low-frequency coefficients,which include the major energy of the original signal.
