Canonical Trees, Compact Prefix-Free Codes, and Sums of Unit Fractions: A Probabilistic Analysis [PDF]
SIAM Journal on Discrete Mathematics, 2015 For fixed $t\ge 2$, we consider the class of representations of $1$ as sum of unit fractions whose denominators are powers of $t$ or equivalently the class of canonical compact $t$-ary Huffman codes or equivalently rooted $t$-ary plane "canonical" trees.

Fast coding unit decision method based on coding tree pruning for high efficiency video coding [PDF]
Optical Engineering, 2012 A fast coding unit (CU) decision method is proposed for high efficiency video coding (HEVC) by determining early the CU sizes based on coding tree pruning. One of the most effective, a newly introduced concept in HEVC, is variable CU size. In determining the best CU size, the reference encoder of the HEVC tests every possible CU size in order to ...

Edge-Based Coding Tree Unit Partitioning Strategy in Inter Prediction [PDF]
, 2014 The High Efficiency Video Coding standard increases in the range of [30, 40] % data compression ratio compared to H.264/MPEG-4 (AVC), but it requires bigger number of operations. HEVC uses a quadtree coding structure. The quadtree partitioning process is a high complexity operation since it employs an exhaustive process, called rate distortion ...
