PENGEMBANGAN DAN ANALISIS KOMBINASI RUN LENGTH ENCODING DAN RELATIVE ENCODING UNTUK KOMPRESI CITRA
Abstract: Data Compression can
save some storage space and accelerate data transfer. Among many compression
algorithm, Run Length Encoding (RLE) is a simple and fast algorithm. RLE can be
used to compress many types of data. However, RLE is not very effective for
image lossless compression because there are many little differences between
neighboring pixels. This research proposes a new lossless compression algorithm
called YRL that improve RLE using the idea of Relative Encoding. YRL can treat
the value of neighboring pixels as the same value by saving those little
differences / relative value separately. The test done by using various
standard image test shows that YRL have an average compression ratio of 75.805%
for 24-bit bitmap and 82.237% for 8-bit bitmap while RLE have an average
compression ratio of 100.847% for 24-bit bitmap and 97.713% for 8-bit bitmap.
