Illustration of the percentages of APACE, LLPACE, and encoded area with different numbers of range blocks in the white boxes encoded. For Lena, (a) LLPACE: 30.46%, APACE: 72.77%, and encoded area: 15.92%. (b) LLPACE: 59.45%, APACE: 87.79%, and encoded area: 29.03%. (c) LLPACE: 91.43%, APACE: 97.03%, and encoded area: 58.30%. For Zelda, (d) LLPACE: 40.53%, APACE: 79.76%, and encoded area: 16.82%. (e) LLPACE: 66.05%, APACE: 90.44%, and encoded area: 32.81%. (f) LLPACE: 92.33%, APACE: 97.51%, and encoded area: 63.09%. For Couple, (g) LLPACE: 38.09%, APACE: 79.98%, and encoded area: 16.21%. (h) LLPACE: 62.99%, APACE: 90.90%, and encoded area: 30.83%. (i) LLPACE: 91.71%, APACE: 98.00%, and encoded area: 56.66%. For Bird, (j) LLPACE: 30.39%, APACE: 72.70%, and encoded area: 10.55%. (k) LLPACE: 64.53%, APACE: 86.99%, and encoded area: 22.07%. (l) LLPACE: 91.53%, APACE: 96.43%, and encoded area: 59.59%.
