run-length encoding
Jump to user comments
A kind of compression algorithm which replaces sequences
("runs") of consecutive repeated characters (or other units of
data) with a single character and the length of the run. This
can either be applied to all input characters, including runs
of length one, or a special character can be used to introduce
a run-length encoded group. The longer and more frequent the
runs are, the greater the compression that will be achieved.
This technique is particularly useful for encoding black and
white images where the data units would be single bit
