Video encoding method for encoding division block, video decoding method for decoding division block, and recording medium for implementing the same

Abstract: Disclosed are a method of encoding a division block in video encoding and a method of decoding a division block in video decoding. An input picture is divided into encoding unit blocks. The encoding unit blocks are divided into sub-blocks. The sub-blocks are encoded by selectively using at least one of intra prediction encoding and inter prediction encoding. A decoding process is performed through a reverse process of the encoding method. When pixel values of an encoding unit block are encoded in video encoding, the flexibility in selecting an encoding mode is increased and the efficiency of encoding is increased.

An H.264/AVC scalable extension and high profile HDTV 1080p encoder chip

Abstract: The first single-chip H.264/AVC HDTV 1080 p encoder for scalable extension (SVC) with high profile is implemented on a 16.76 mm2 die with 90 nm process. It dissipates 349/439 mW at 120/166 MHz for high profile and SVC encoding. The proposed frame-parallel architecture halves external memory bandwidth and operating frequency. Moreover, the prediction architecture with inter-layer prediction tools are applied to further save 70% external memory bandwidth and 50% internal memory access.

Synaptic Clustering and Memory Formation.

Abstract: In the study of memory engrams, synaptic memory allocation is a newly emerged theme that focuses on how specific synapses are engaged in the storage of a given memory. Cumulating evidence from imaging and molecular experiments indicates that the recruitment of synapses that participate in the encoding and expression of memory is neither random nor uniform. A hallmark observation is the emergence of groups of synapses that share similar response properties and/or similar input properties and are located within a stretch of a dendritic branch. This grouping of synapses has been termed "synapse clustering" and has been shown to emerge in many different memory-related paradigms, as well as in in vitro studies. The clustering of synapses may emerge from synapses receiving similar input, or via many processes which allow for cross-talk between nearby synapses within a dendritic branch, leading to cooperative plasticity. Clustered synapses can act in concert to maximally exploit the nonlinear integration potential of the dendritic branches in which they reside. Their main contribution is to facilitate the induction of dendritic spikes and dendritic plateau potentials, which provide advanced computational and memory-related capabilities to dendrites and single neurons. This review focuses on recent evidence which investigates the role of synapse clustering in dendritic integration, sensory perception, learning, and memory as well as brain dysfunction. We also discuss recent theoretical work which explores the computational advantages provided by synapse clustering, leading to novel and revised theories of memory. As an eminent phenomenon during memory allocation, synapse clustering both shapes memory engrams and is also shaped by the parallel plasticity mechanisms upon which it relies.

Imagination and false memory inductions: investigating the role of process, content and source of imaginations

Abstract: Three experiments examined the influence of imaginal encoding on false memory rates induced by the Deese-Roediger-McDermott (DRM) paradigm. Several features of imaginal encoding were investigated including the processes giving rise to the images (automatic or deliberate), the source of imagery scripts (participant or another person), and imagery content (e.g. individual or integrated images). Deliberately generating images led to a reduction in false memory rates relative to an imagery control condition. However, the effects on false memory rates very much depended on features characterizing the imaginal encoding. Most notably, when participants (rather than someone else) specified the scripts for guiding their imagery experiences, false memory rates were considerably less. Extending the generality of the distinctiveness heuristic as an explanation for the reduction in false memory rates following pictorial encoding, the results also speak to debates about the wisdom of using guided imagery techniques in applied settings.
