Abstract:
A method and apparatus control delivery of media data in a transmission system. A method of operating a sending entity in the transmission system includes identifying a fixed delay associated with transmission of media data in the transmission system and sending information about the fixed delay as a requirement on a length of time after transmission that the media data is passed to an application layer component or presented to a user of a receiving entity. A method of operating a receiving entity in the transmission system includes receiving media data and information about a fixed delay associated with the media data and identifying a requirement on a length of time after transmission that the media data is passed to an application layer component or presented to a user from the information about the fixed delay.
Abstract:
A method and apparatus control receiving media data in a transmission system. A method of operating a receiving entity in the transmission system includes receiving packets for media data and information about a fixed delay associated with the media data. The method also includes identifying a requirement configured to guarantee that the packets for the media data are delivered to an upper layer of the receiving entity after the fixed delay, from the information about the fixed delay. The method further includes identifying a buffer size requirement for the receiving entity estimated based on the fixed delay and Nitrate information associated with the media data; and delivering the packets to the upper layer of the receiving entity.
Abstract:
To improve feature selection accuracy during a visual search, interest points within a query image are two-way matched to features in an affine transformed image or otherwise transformed version of the query image. A user device implements a method for selecting local descriptors in the visual search. The method includes: detecting a first set of interest points for the original image; computing an affine transform matrix; computing a new image as a transformation of the original image using the affine transform matrix; detecting a second set of interest points from the and new image; performing a two-way matching between the first set of interest points and the second set of interest points; sorting matching pairs according to a specified self-matching score (SMS); assigning an infinite value to SMS of unmatched interest points from the original image; selecting the interest points based on SMS. Significant performance gains reduce false positive matches.

Abstract:
A method of operating a sending entity in the transmission system includes identifying a fixed delay associated with a transmission of media data in the transmission system and sending, to a receiving entity, information about the fixed delay as a requirement being configured to guarantee that packets for the media data, received by the receiving entity, are delivered to an upper layer of the receiving entity after the fixed delay. A method of operating a receiving entity in the transmission system includes receiving media data and information about a fixed delay associated with the media data and identifying a requirement, being configured to guarantee that packets for the media data are delivered to an upper layer after the fixed delay, from the information about the fixed delay.
Abstract:
To reduce communication costs and computational complexity, only a subset of ranked SIFT points within a query image for a visual search request is transmitted to the visual search server in each iteration of an incremental search. For each candidate match, a flag identifying the matching points is returned by the server for use in computing holistic (e.g., histogram) information for a bounding box within the query image including the matching points. Distance from that query image holistic information is used to reject images from a short list used for a subsequent iteration, if any. If all images are rejected or a match criteria is met during one iteration, the search may terminate early without consideration of remaining SIFT points.
