Examples include a device for coding video data, the device including a memory configured to store video data, and one or more processors configured to obtain adaptive loop filtering (ALF) information for a current coding tree unit (CTU) from one or more of: (i) one or more spatial ...
Example of CTU quad-tree structure defined in HEVC Full size image In the CU partition structure in HEVC, four different CU sizes are supported by default; these are64×64,32×32,16×16and8×8, corresponding to four CU depths of 0, 1, 2 and 3. For a coding unit U, the first-leve...
The mechanism includes receiving a bitstream comprising one or more sub-pictures partitioned from a picture such that each sub-picture includes a sub-picture width that is an integer multiple of a coding tree unit (CTU) size when the each sub-picture includes a right boundary that does not ...
HEVC (High Efficiency Video Coding) as one of the newest international video coding standard, can achieve about 50% bit rate reduction compared with H.264/AVC (Advanced Video Coding) with the same perceptual quality by the use of flexible CTU (coding tree unit) structure, but at the same ...
basic tree construction traversal manipulation algorithms BFS(breadth-first search) and DFS(depth-first search) (video) BFS notes: level order (BFS, using queue) time complexity: O(n) space complexity: best: O(1), worst: O(n/2)=O(n) DFS notes: time complexity: O(n) space complex...
1b) were clustered into co-expression modules by dynamic tree cut. The log-fold change is relative to the untreated cells. C15ORF48 resides in Module 2. (Right) Panther GO analysis of genes in Module 2 and closely related Module 3 reveal significant enrichments in the ontologies depicted. ...

In Intra prediction for Quality SHVC, Coding Tree Unit (CTU) allows recursive splitting into four depth levels, which considers 35 Intra prediction modes and interlayer reference (ILR) mode to determine the best possible mode at each depth level. This achieves the highest coding efficiency but ...
In particular, at the Coding Tree Unit level, the partition parameters of QTBT are dynamically derived to adapt to the local characteristics without transmitting any overhead. Subsequently, at the Coding Unit level, a joint-classifier decision tree structure is designed to eliminate unnecessary ...
