Multimedia content processing through cross-modal association

Abstract: Multimodal information processing has received considerable attention in recent years The focus of existing research in this area has been predominantly on the use of fusion technology In this paper, we suggest that cross-modal association can provide a new set of powerful solutions in this area We investigate different cross-modal association methods using the linear correlation model We also introduce a novel method for cross-modal association called Cross-modal Factor Analysis (CFA) Our earlier work on Latent Semantic Indexing (LSI) is extended for applications that use off-line supervised training As a promising research direction and practical application of cross-modal association, cross-modal information retrieval where queries from one modality are used to search for content in another modality using low-level features is then discussed in detail Different association methods are tested and compared using the proposed cross-modal retrieval system All these methods achieve significant dimensionality reduction Among them CFA gives the best retrieval performance Finally, this paper addresses the use of cross-modal association to detect talking heads The CFA method achieves 911% detection accuracy, while LSI and Canonical Correlation Analysis (CCA) achieve 661% and 739% accuracy, respectively As shown by experiments, cross-modal association provides many useful benefits, such as robust noise resistance and effective feature selection Compared to CCA and LSI, the proposed CFA shows several advantages in analysis performance and feature usage Its capability in feature selection and noise resistance also makes CFA a promising tool for many multimedia analysis applications

Leveraging resources in global software development

Abstract: Leveraging global resources for software development is rapidly becoming the norm at Motorola, which has over 25 software development centers worldwide. Our project, called the 3G Trial (Third Generation Cellular System), was the first of its scope and significance developed by a global engineering team at Motorola. Staffing was the most significant issue we encountered in the 3G Trial. We had only about 20 percent of the required staff available at our division headquarters in Burlington Heights, Ill., US, and needed to find the other 80 percent to successfully complete the project. Early on, we concluded that our only means to staff the project was to rely on software development engineers from Motorola's worldwide software centers. We developed the system with staffing from six different countries. Next, we had to integrate the people into a team. While addressing this challenge, we identified key risk factors and developed approaches to reduce them. We separated the project risk factors into the five categories Carmel (1999) describes as the centrifugal forces that pull global projects apart. To pass on the lessons we learned from this project, this article sets out the global development issues we faced, our approaches to resolving them, and our findings compared to other research.

Geo-Location Database Techniques for Incumbent Protection in the TV White Space

Abstract: The opening of the television bands in the United States presents an exciting opportunity for secondary spectrum utilization. Protecting licensed broadcast television viewers from harmful interference due to secondary spectrum usage is critical to the successful deployment of TV white space devices. A wide variety of secondary system operating scenarios must be considered in any potential interference analysis, as described below. Several different types of licensed television transmitters currently exist in the TV bands, along with secondary licensed services, such as wireless microphones. All licensed services must be adequately protected from harmful interference, which can readily and reliably be achieved with the described geo-location database methods. Specific implementation details of geo-location databases are discussed, including several complexity reduction techniques. Geo-location database techniques are also shown to more efficiently utilize available spectrum than other spectrum access techniques.

Dynamic pricing method and apparatus for communication systems

Abstract: A communication system service billing arrangement is described that adapts to system loading in realtime. As system loading varies, one or more individual subscribers units(ISU) (15,20) of a communication system (8) are provided with realtime information on the current cost of the communication service. The system determines the locations of the ISUs (34) and the current loading there between (31) and calculates a calling rate (32) based at least on the current loading. This calling rate (42) is sent (43) to at least one of the ISUs (15) whose operator can choose to connect or not connect the call between the ISUs based on the current realtime variable rate.

Low-profile microelectronic package

Abstract: A microelectronic package (10) is formed by placing a lead frame (22) onto an adhesive polyimide tape (38). The lead frame (22) includes a plurality of metallic leads (16) and an opening. An integrated circuit die (12) is positioned onto the molding support (38) within the opening such that a non-active face (32) of the integrated circuit die (12) rests against the molding support (38). Wire leads (18) connect an active face (28) of the integrated circuit die (12) to the metallic leads (16). A plurality of metallic bumps (20) are attached to the metallic leads (16), and a polymeric precursor is dispensed. The precursor embeds the active face (28) of the integrated circuit die (12), the inner surface (19) of the metallic leads (16), the wire leads (18), and the metallic bumps (20). The microelectronic package (10) is then heated to cure the polymeric precursor to form a polymeric body (14). The microelectronic package (10) is then capable of being tested and subsequently attached to a printed circuit board (40) to form a low-profile microelectronic assembly (11).
