摘要： A method and apparatus for deblocking of reconstructed video are disclosed. In one embodiment, the method divides a block boundary into two sub-boundaries and separates lines or column across the sub-boundaries into two groups. The deblocking filter decision for each group is determined based on the lines or columns in the respective group. In another embodiment, the method divides block edges of blocks in the LCUs into two edge groups, where the first edge group corresponds to horizontal block edges between two LCUs and the second edge group corresponds to remaining block edges not included in the first edge group. The number of lines processed by a vertical filter in the first edge group is less than the number of lines processed by a vertical filter in the second edge group. Accordingly, a system embodying the present invention has reduced storage requirement.

摘要： Systems and methods for describing video content establish video description records which include an object set (24), an object hierarchy (26) and entity relation graphs (28). Video objects can include global objects, segment objects and local objects. The video objects are further defined by a number of features organized in classes, which in turn are further defined by a number of feature descriptors (36, 38, and 40). The relationships (44) between and among the objects in the object set (24) are defined by the object hierarchy (26) and entity relation graphs (28). The video description records provide a standard vehicle for describing the content and context of video information for subsequent access and processing by computer applications such as search engines, filters and archive systems.
摘要翻译：用于描述视频内容的系统和方法建立包括对象集（24），对象层次（26）和实体关系图（28）的视频描述记录。视频对象可以包括全局对象，段对象和本地对象。视频对象由类别中组织的多个特征进一步限定，这些特征又由多个特征描述符（36,38和40）进一步限定。对象集合（24）中的对象之间和之间的关系（44）由对象层次结构（26）和实体关系图（28）定义。视频描述记录提供用于描述视频信息的内容和上下文的标准车辆，以便随后通过计算机应用（例如搜索引擎，过滤器和归档系统）进行访问和处理。
