Interpreting a 3D object from a rough 2D line drawing

Abstract: Visualizing the third dimension while designing three-dimensional (3-D) objects is an awkward process in mechanical computer-aided-design (CAD) systems, given the current state of the art. The authors describe a computer system that automatically constructs the shape of a 3-D object from a single 2-D sketch. The method makes it convenient to create and manipulate 3-D objects, and is thus seen as an intelligent user interface for CAD and 3-D graphics applications. The proposed technique is built on well-known results in image analysis. These results are applied in conjunction with some perceptual rules to determine 3-D structure from a rough line drawing. The principles are illustrated by a computer implementation that works in a nontrivial object domain. >

Software upgradable dashboard

Abstract: A dashboard for a vehicle, comprising a monitor which displays graphical images depicting dashboard instruments. In one embodiment, the monitor is a general purpose LCD graphics display coupled to a graphics generator. The graphics generator is a processor which executes a virtual dashboard software application. The processor receives vehicle information such as speed, fuel level, mileage and battery charge, and processes this information using the virtual dashboard software application to generate graphics signals which are transmitted to the monitor for display to the driver. The images displayed to the driver are determined by the virtual dashboard application, and not by the monitor itself. The displayed images are user-selectable so that they can be varied to suit the preferences of different drivers. The driver may alternately select different groups of images to view on the monitor using touch screens or speech commands.

In-store advertising system

Abstract: An in-store advertising system for displaying advertisements involves preparing graphical art from the actual products or from flat art, for each advertised product. Each frame is stored in computer memory as a digital graphics file. As desired, pricing and advertising copies are added as overlays to the digital art of each frame. Control data is defined for each frame indicating its destination location(s) and the run time for each destination location. The digital graphic files containing a digital frame and the respective control data for each frame are then loaded into an uplink control computer. The control data is analyzed by the uplink computer to compute an adlist which lists the digital frames and their respective destination locations. The uplink control computer is interfaced to a satellite addressable network control system (ANCS) to unmute the desired satellite receiver(s) at the remote location(s), based upon a predefined transmission script. The uplink computer then transmits the respective graphic files, control data and adlist via a satellite transmitter to a commercial broadcasting satellite. The remote receivers display the graphic data based on the code data.

Active hand tracking

Abstract: This paper describes a system which uses multiple visual processes to detect and track hands for gesture recognition and human-computer interaction. This system is based on an architecture in which a supervisor selects and activates visual processes. Each process provides a confidence factor which makes it possible for the system to dynamically reconfigure itself in response to events in the scene. Visual processes for hand tracking are described using image differencing and normalized histogram matching. The result of hand detection is used by a recursive estimator (Kalman filter) to provide an estimate of the position and size of the hand. The resulting system provides robust and precise tracking which operates continuously at approximately 5 images per second on a 150 megahertz Silicon Graphics Indy.
