Method, device and computer program product for integrating code-based and optical character recognition technologies into a mobile visual search

Abstract: A device for switching between code-based searching, optical character recognition (OCR) searching and visual searching is provided. The device includes a media content input for receiving media content from a camera or other element of the device and transferring this media content to a switch. Additionally, the device includes a meta-information input capable of receiving meta- information from an element of the device and transferring the meta-information to the switch. The switch is able to utilize the received media content and the meta- information to select and/or switch between a visual search algorithm, an OCR algorithm and a code-based algorithm.

Mobile station having method and apparatus for displaying user-selectable animation sequence

Abstract: A wireless mobile station (10), such as a cellular telephone, executes a method to selectively display one of a plurality of graphical information sequences on a display (20) of the mobile station. The graphical information sequence is displayed during an Idle state of the mobile station, that is, when the mobile station is not involved in receiving a call or during a call. By example, the graphical information sequence can be displayed when the mobile station is in a Keyguard state, and/or in a Charging state, or when the mobile station is first powered on. In a further aspect of this invention the user interface (20, 22) of the mobile station is adapted to enable the user to selectively: enable or disable the display of a graphical information sequence; and/or select a graphical information sequence to be displayed from a plurality of pre-stored graphical information sequences; and/or input a definition of a graphical information sequence from an external source for storage in the mobile station.

Unified Real-Time Tracking and Recognition with Rotation-Invariant Fast Features

Abstract: We present a method that unifies tracking and video content recognition with applications to Mobile Augmented Reality (MAR). We introduce the Radial Gradient Transform (RGT) and an approximate RGT, yielding the Rotation-Invariant, Fast Feature (RIFF) descriptor. We demonstrate that RIFF is fast enough for real-time tracking, while robust enough for large scale retrieval tasks. At 26× the speed, our tracking-scheme obtains a more accurate global affine motionmodel than the Kanade Lucas Tomasi (KLT) tracker. The same descriptors can achieve 94% retrieval accuracy from a database of 104 images.

A tunable filter and method of tuning a filter

Abstract: A bandpass filter is tuned by converting the filter into an oscillator using a negative resistance circuit, tuning the oscillator by using conventional tuning techniques such as tuning a varactor via a phase locked loop, sampling and holding the tuning signal and switching off the negative resistance circuit to convert the oscillator back into a bandpass filter.

Group information management

Abstract: A communication system including a first administrative subsystem and a second administrative subsystem providing group communication service. The system includes a first server for storing group and list management information of subscribers of the first administrative subsystem. The system also includes a second server for storing group and list management information of subscribers of the second administrative subsystem., Further, the system includes an interface for exchanging group and list management information between the first server and the second server. In addition, the system reduces ambiguity in group information management of integrated systems that include two or more administrative domains.
