This paper propose a video copy detection method based on structure information and temporal ordinal measure. Firstly each frame is divided into a grid and calculate the difference of the mean of block brightness, then we treat these values as the structure information of each frame, whereas, along the time series these values are sorted in an ordinal ranking sequence, we put them as the temporal...
The fast evolution of hardware and the internet made large volumes of data more accessible. This data is composed of heterogeneous data types such as text, numbers, multimedia, and others. Non-overlapping research communities work on processing homogeneous data types. Nevertheless, from the user perspective, these heterogeneous data types should behave and be accessed in a similar fashion. Processing...
The problem that the shoeprints found at crime scenes are often poor quality and with lots of noise causes much trouble when extracting the basic shapes and later classifying the database of shoeprint images automatically. In this paper we present a shoeprint image retrieval method based on odd and even Gabor filter. The method combines odd and even Gabor filter to extract the texture and geometry...
Data integration is the problem of combining data residing at different sources, and providing the user with a unified view of these data. One of the critical issues of data integration is the detection of similar entities based on the content. This complexity is due to three factors: the data type of the databases are heterogeneous, the schema of databases are unfamiliar and heterogenous as well,...
With the growing computer networks, accessible data is becoming increasingly distributed. Understanding and integrating remote and unfamiliar data sources are important data management issues. In this paper, we propose to utilize self-organizing maps (SOM) clustering to aid with the visualization of similar columns, and integration of relational database tables and attributes based on the content...
