Generalization of Repetitiveness Measures for Two-Dimensional Strings
Lorenzo Carfagna, Giovanni Manzini, Giuseppe Romana +2
The problem of detecting and measuring the repetitiveness of one-dimensional strings has been extensively studied in data compression and text indexing. Our understanding of these…
