bmp2rle
Encode bitmap(bmp) file with run-length encoding
Encode bitmap(bmp) file with run-length encoding(RLE), just like RLE4 and RLE8, but extend to RLE16, RLE24 and RLE32. Usually, this project will be used in GUI of embedded system, to make the image files smaller, and save the IO bandwith. If the GUI support JPG or PNG, the compression ratio is much better than RLE, but how about the embedded system encounters both caculate limitation and IO bandwidth limitation? Try this project, I hope it can make a banlance between caculation and bandwidth. But first of all, you should know that the compression ratio of RLE is highly depend on the bitmap file data, the ratio can larger than 1, only when the same color continuously repeats in one line, it will gain a smaller compression ratio. -

Arpeggio
Harmonic analysis of ChIP-seq experiments
Researchers generating new genome-wide data in an exploratory sequencing study can gain biological insights by comparing their data with well-annotated datasets possessing similar genomic patterns. Data compression techniques are needed for efficient comparisons of a new genomic experiment to large repositories of publicly available profiles. Arpeggio allows us to efficiently compare numerous ChIP-seq datasets consisting of many types of DNA-binding proteins collected from a variety of cells, conditions and organisms. Importantly, these interaction patterns broadly reflect the biological properties of the binding events. ... -

Parallel DPCM
C# Parallel implementation of DPCM alogrithm
An implementation of the DPCM algorithm for compressing and decompressing an avi video file. It shows the compression size, as it is saved in a txt file near the avi original file. The decompression results in another avi file, saved near the original file. If the width and height of the frames aren't a multiple of 16, they are completed with black pixels. The pixel macroblocks of 16x16 are generated on separate threads for each frame and they are replaced on frames at decompression sequentially. ... -
