SQL language extensions for modifying collection-valued and scalar valued columns in a single statement

A technique for updating collection-valued and other complex structured columns in a nested table using a nested extension of an UPDATE statement that uses syntax and semantics to modify collection-valued columns in a way that is analogous to the syntax and semantics of the UPDATE statement that is used to modify scalar-valued columns of the table (called the outer UPDATE). Using the same syntactic and semantic constructs as the table at the outer level allows an existing implementation that processes modifications to relational tables to reuse its implementation techniques for processing outer updates to modify collection-valued columns as well. The UPDATE extensions enable the specification of updates to nested collections embedded at arbitrary levels of depth in the object model. The new syntax is embedded inside the outer UPDATE statement in a way that parallels the structure of the data itself and thus maps more directly to the user's conceptual model of the data. The method for implementing the UPDATE extensions uses a change descriptor, which is a data structure that aggregates substantially all changes, both scalar and collection-valued into a single value that can be applied to the changed collection-valued column. This technique can also be used for modifications to other kinds of complex-structured columns such as objects or xml. The change descriptor includes hierarchical information for the cell, thereby enabling efficient application of multiple updates at various granularity levels in a single operation and enabling the implementation of efficient index maintenance algorithms by updating only the indexes affected by the UPDATE operation and updating only those index rows that were affected by the UPDATE operation.

Stereoscopic image non-reference quality evaluation method based on visual perception characteristics

InactiveCN103763552AHigh precisionAccurate Stereoscopic Image Quality Evaluation ResultsTelevision systemsSteroscopic systemsTime domainImaging quality
The invention relates to a stereoscopic image non-reference quality evaluation method based on visual perception characteristics. The method includes the steps that firstly, a region in which the human eyes are interested in an image is selected through a visual prominence model algorithm; secondly, a depth map for representing stereoscopic visual information is extracted from the region of interest as an evaluation basis through a left view and a right view; thirdly, characteristic statistical treatment is conduced on the depth value of the region, and the influence of human eye depth sensitive characteristics on depth perception is considered in the process; eventually the video sequence depth quality value is calculated by the combination of characteristic information of time domains. Compared with a traditional method, the stereoscopic image non-reference quality evaluation method has the advantages that result accuracy is greatly improved, high generating efficiency of the depth map is possessed, weight factors for representing that the depth level affects human eye depth sensitivity are added in a stereoscopic feeling quality evaluation model, and then stereoscopic image quality is more accurately evaluated.

Panoramic video stitching method based on multi-depth image transformation matrix

The invention discloses a panoramic video stitching method based on a multi-depth image transformation matrix. The panoramic video stitching method based on the multi-depth image transformation matrix comprises the following steps: synthesizing a plurality of videos provided with mutually overlapped regions and shot by a plurality of cameras into a panoramic video. The method comprises a background calibration process and a real-time stitching process. A reference planar image transformation matrix with an infinitive depth is obtained in the background calibration process, and besides, other depth information is divided into different depth levels, so that a planar image transformation matrix corresponding to each depth level is obtained; in the real-time stitching process, a reference panoramic image is obtained by using the reference planar image transformation matrix, besides, the current depth information in the overlapped region is calculated, and the panoramic image of the overlapped region is obtained according to the image transformation matrix corresponding to the depth information; finally, the panoramic image of the overlapped region and the reference panoramic image are mixed into the panoramic video image. The method disclosed by the invention can obtain stable, continuous and high-quality panoramic video, and the method has the characteristics of small calculated amount and high running speed.
