The TZSearch algorithm was adopted in the high efficiency video coding reference software HM as a fast Motion Estimation (ME) algorithm for its excellent performance in reducing ME time and maintaining a comparable Rate Distortion (RD) performance. However, the multiple initial search point decision and the hybrid block matching search contribute a(More)
—The coding performance can be further improved when the hierarchical B-picture coding is introduced into H.264/AVC. However, the existing rate control schemes can NOT work efficiently in such new coding framework. This paper proposes a novel rate control algorithm when hierarchical B-picture coding is used in H.264/AVC. Firstly, a set of scaling-factors(More)
OBJECTIVE The presence of interstitial cells of Cajal (ICC) has been described throughout the digestive tract. In this study, we investigated whether ICC also exist in the gallbladder wall of CD1 mice. MATERIAL AND METHODS Immunofluorescent confocal microscopy was used to identify the morphology and distribution of ICC in either whole-mount flat(More)
Targeted gene delivery provides enormous potential for clinical treatment of many incurable diseases. Liposomes formulated with targeting ligands have been tested extensively both in vitro and in vivo, and many studies have strived to identify more efficacious ligands. However, the environment of the ligand within the delivery vehicle is generally not(More)
In this paper, we address the problem of human action recognition by representing image sequences as a sparse collection of patch-level spatiotemporal events that are salient in both space and time domain. Our method uses a multi-scale volumetric representation of video and adaptively selects an optimal space-time scale under which the saliency of a patch(More)
Perceptual quality evaluation of the retargeting image plays an important role in benchmarking different retargeting methods , as well as guiding or optimizing the retargeting process. The distortions introduced during the retargeting process are mainly categorized into shape distortion and content information loss [1]. The shape distortion measurement is(More)
OBJECT Cerebral arteriovenous malformations (AVMs) are congenital malformations that may grow in the language cortex but usually do not lead to aphasia. In contrast, language dysfunction is a common presentation for patients with a glioma that involves language areas. The authors attempted to demonstrate the difference in patterns of language cortex(More)
The ability to deliver nucleic acids (e.g., plasmid DNA, antisense oligonucleotides, siRNA) offers the potential to develop potent vaccines and novel therapeutics. However, nucleic acid-based therapeutics are still in their early stages as a new category of biologics. The efficacy of nucleic acids requires that these molecules be delivered to the interior(More)
