Run-length matrices

WebbA run is a consecutive sequence of repeated values or observations. For repeated values, R's "run-length encoding" concisely describes a vector in terms of its runs. Consider: dat <- c (1, 2, 2, 2, 3, 1, 4, 4, 1, 1) We have a length-one run of 1s; then a length-three run of 2s; then a length-one run of 3s; and so on. Webb25 nov. 2024 · Gray-level run length matrices (GLRLMs) are higher order texture matrices that measure runs of voxels with the same gray-level along a given direction . GLRLM_RLNU is a GLRLM feature that measures differences between the lengths of runs; similar lengths result in low RLNU values [ 35 ].
