Map-matching is the process of aligning a sequence of observed user positions with the road network on a digital map. It is a fundamental pre-processing step for many applications, such as moving object management, traffic flow analysis, and driving directions. In practice there exists huge amount of low-sampling-rate (e.g., one point every 2--5 minutes) GPS trajectories. Unfortunately, most current map-matching approaches only deal with high-sampling-rate (typically one point every 10--30s) GPS data, and become less effective for low-sampling-rate points as the uncertainty in data increases. In this paper, we propose a novel global map-matching algorithm called ST-Matching for low-sampling-rate GPS trajectories. ST-Matching considers (1) the spatial geometric and topological structures of the road network and (2) the temporal/speed constraints of the trajectories. Based on spatio-temporal analysis, a candidate graph is constructed from which the best matching path sequence is identified. We compare ST-Matching with the incremental algorithm and Average-Frechet-Distance (AFD) based global map-matching algorithm. The experiments are performed both on synthetic and real dataset. The results show that our ST-matching algorithm significantly outperform incremental algorithm in terms of matching accuracy for low-sampling trajectories. Meanwhile, when compared with AFD-based global algorithm, ST-Matching also improves accuracy as well as running time.

A method and system for automatically configuring a hand-held electronic device for accessing a site on a public network is disclosed. The method and system include establishing a connection to a website server, which is responsible for establishing and maintaining website accounts, and sending information uniquely identifying the electronic device to the website server. The server then sends user account information to the device, including an account ID and password, created based on the electronic device information. The user account information is then stored on electronic device for use the next time the electronic device accesses the website, whereby the user does not have to enter account information in order to establish the ISP connection or the website account before accessing the public network.

Automatically Configuring A Web-Enabled Digital Camera To Access The Internet

A method and system for merging metadata with digital images is disclosed, where the digital images are stored as image files having metadata fields associated therewith. The method and system include receiving data uploaded from a remote location, providing a web application to a client device over a network when requested, and transmitting the previously uploaded data to the web application. When an image requires input of metadata on the client device, the uploaded data is displayed on the client device for selection by the user. In response to the user's selection, the selected data is then used to automatically populate the metadata fields associated with the image file.

Client-server system for merging of metadata with images

The present invention provides a method for establishing a location for a digital image without the use of a GPS unit. Aspects of the invention include broadcasting over a network a location identifier (ID) identifying a location of the network; detecting the location ID by a digital image capture device coupled to the network; and in response to the image capture device capturing a digital image when in communication with the network, associating the location ID with the digital image.

A method and apparatus for enabling a user to define a panning and zooming path across a still image in a digital imaging device during interactive movie creation. The method and apparatus include allowing the user to define the position of a plurality of key frames on the still image, allowing the user to size the key frames to control the zoom during the movie, and allowing the user to set the key frames on the still image to fix each of the key frame's position and size.
