Bijective BWTS-DC-FIB 0 36 (12/15/2010 5:11:36 PM) comp.compression I have code which is a first cut of a bijective BWTS-DC-FIB compressor. It does not compress to the smallest yet since there is no entropy coder and a universal code is used instead. You can get it at http:/... biject

combine a number field with a string? 8 98 (10/24/2010 11:20:34 PM) comp.compression I have a question what is the optimal way to combine a number with a bit string to form a new string that carries the same information with the shortest length possible? I ask this question because I do not... biject

DNA compression 3 316 (1/21/2010 4:18:18 AM) comp.compression I wrote this more of as a first step in DNA compression using very simple bijective techniques this bijective transforms between to file spaces one all files and one that is made of the 4 lower case ascii sy... biject

Huffman versus arithmetic compress for fixed static compression 8 133 (1/18/2010 4:00:36 PM) comp.compression There was a long thread about how to best compress something with 75 to 25 zeroes to ones. And most realized this is like an I.I.D source produced file. Where each time a symbol occurs there a probability ... biject

BIJECTIVE BWTS PAPER 5 32 (9/10/2009 7:22:15 PM) comp.compression Many of you know that a paper was submitted to the SODA conference on the BWTS. I did not write it but worked with a guy good at writing. It was rejected. I am not surprised! here is sentence from one of the r... biject

NF3 in Lossless compression handbook By Khalid Sayood 0 118 (8/25/2009 10:24:47 PM) comp.compression I have written compression code that use standard Fibonacci order 2 code That is 1 to 8 is as follows 1 11 2 011 3 0011 4 1011 5 00011 6 10011 7 01011 8 000011 Now I have been thinking of using for a project... biject

The BWTS or BWT Scottified 26 106 (3/11/2009 5:33:36 PM) comp.compression It been since 2007 when I posted on this group with this subject and had sample code. A truely BIJECTIVE BWT is here! What I am curious about is how many of you have used this transform as a subsutitue fo... biject

TRYING TO MAKE EXE RUN ON FRIENDS MACHINE 51 63 (1/3/2009 3:17:14 PM) comp.os.msdos.djgpp I have used DJGPP for years. The problem is this my executable does not run on a VISTA 64 bit machine. Is there a way to make an executable that will run on his machine with DGJPP. my machine is XP I want it t... blueice

HCM BLACK PAPER 0 26 (8/28/2008 3:23:44 PM) comp.compression Mr E as he calls himself breaks a file up into 3 files plays compression gains/ And thinks that if he remakes a sigle file out of it that it will be smaller than the original file. He makes the false assumpti... biject

Good News! Software Patents are in Jeopardy 33 29 (7/25/2008 1:55:25 AM) comp.compression I have a played the Patent game got one while working for Uncle Sam. But I notice many people are afraid to write code because of patents. And in the computer world there are many patents that don't make cents... biject

Huffman Codes on an 8-bit computer? 16 34 (10/6/2011 1:18:05 PM) comp.compression I am working on a new file compression technique and need a little help: I need to predict how much memory is saved by implementing the technique over not on an 8-bit computer. 8-bit computers generally don't ... rose.joseph12 (88)

New guy trying to avoid the mistakes of others 19 39 (8/29/2011 11:13:21 PM) comp.compression A friend and I are working on a method for data compression that looks promising, but I remain... wary. From what I've seen it should work, and my high-school calculus limited mathematics are showing promise. T... draloff (2)

"Distance To" encoding the dynamic cousin of Move to Front? 10 27 (3/7/2011 8:53:05 PM) comp.compression Distance to encoding the dynamic cousin of Move to Front? A little while back I was exploring the possibility of encoding 18 symbols with 4 bits. I studied the effect Move to Front had and also thought ... Ernst_Berg (156)

arithmetic encoding with rationals 3 32 (2/14/2011 12:46:56 PM) comp.compression hi I'm trying to implement artithmetic coding in a programming language which has built-in support for arbitrary size rational numbers, so my first version is straightforward implementation with rationals.

how to combine the probability of disjoint symbol models? 9 26 (3/22/2012 12:35:23 PM) comp.compression As a thought exercise I am attempting to see whether there is some gains to be made via a statistical compression of an already compressed file (as output from another compression method, e.g. LZMA ) My curren... budgetanime (14)

entropy of a binary file with conditions 23 37 (3/3/2012 9:04:29 AM) comp.compression hi, let's suppose we have a binary file (runs of zeroes and ones) and its length is 1024 bits. any of these runs is not bigger than 8 (00000000 or 11111111) how can one compute the entropy of such a file ? ... pierre9167 (6)

What do you call this? 10 41 (2/11/2012 5:10:45 PM) comp.compression With a PRNG I can generate a stream of bytes of any size from any range. If I select 0-127 then it will generate a random distribution of hex bytes 00 to 7F, and WinRAR will compress it by 12.5%, as expected. I... industrial_one (55)
