runindex

version 3.1.2

by Jos (10584)

linear indices for each run in a vector (run length encoding, and decoding)

] = rundindex(V) also returns a run length encoding of V in the N-by-3 array RLE. Each row is a run, with the value in the first column, the start index in the second column, and the run length

RunLength coding as fast MEX and M-code

RUNLENGTH - Run-length codingRun-length encoding splits a vector into one vector, which contains theelements without neighboring repetitions, and a second vector, whichcontains the number of

Bit plane encoding of an image uses run length coding algorithm to get the number of runs of zeros and ones in each plane.

format is stored in a structure for all eight plane with first column representing the number of ones or zeros and the second column representing the bit one / zero. Also run length coding can be done
