Background. Image content description is used in a wide range of applications, including web-scale image search and real-time object recognition, but the effectiveness is constrained by a computational bottleneck.
The invention introduces a method for providing compact descriptors for visual search, in which local image features are extracted and a global image signature is formed from these local descriptors. Global features may be much smaller than local features.
A method of tracking an inventory of objects via a mobile communications device includes acquiring an image of one or more of the objects via the mobile communications device, which also collects a location of the mobile communications device while acquiring the image of the o
A system for enabling streaming video to a mobile client includes a plurality of fixed node peers linked to the mobile client via one or more networks as well as a video source linked to fixed node peers and configured to provide streaming video data representing a video prese
Mobile devices often connect to the network via wireless channels. In general, the downlink of the wireless channel (e.g., the cellular access network) is limited in throughput.
Local image features have become pervasive in the areas of computer vision and image retrieval and are increasingly finding application in real-time object recognition, 3-D reconstruction, panorama stitching, robotic mapping, and video tracking.
This invention offers a cost-effective solution to streaming video to mobile users. A prototype has been implemented in software, demonstrating its low operational cost based on peer-to-peer technology and its robustness to peer failure.
Stanford researchers developed and patented a receiver-based playout scheduling scheme in conjunction with improved playout algorithms to reduce packet buffering delay and packet loss for VoIP communication.
