JPEG-LS image after LSS slope recovery algorithm
Figure 4. Errors in slope: For 3 images, the error in slope is measured
for both JPEG-LS compression with
and without LSS' slope recovery method. The errors on the chart
are in percentages and
the comparison is made for fixed compression ratios.
Figure 5. Compression ratios:
For 3 images, the compression ratio is measured for both JPEG-LS compression
and without LSS' slope recovery method. The numbers are the compression
the compression is made for a fixed error in slope.
