摘要： The application discloses an apparatus and method of processing images, hand-drawn or written on a suitable Writing Surface, viewed by an Image Sensor such as a video camera, and captured by an image sensing circuit (i.e., frame grabber or similar) used for acquisition of image frames by a computer. More particularly, this invention discriminates among changes detected in these Viewed Images in order to identify and disregard non-informational, transient and/or redundant content. Removal of such content, a writer's arm for example, from the captured image facilitates isolating meaningful changes, specifically intentional new Writings and Erasures appearing on the Writing Surface. Preserving only meaningful changes on the surface promotes optimized: “video image” storage and compressed transmission of a subset of the visual data, when used in conjunction with digital computers at remote locations optionally equipped with projected image and/or conventional computer display systems. The invention provides for displaying a composite of the remote sites' changes, transmitted over conventional communications channels, omitting Local Markings where the display device is a projector. The preferred embodiment of the present invention is applied to remote presentation aids, in particular “whiteboards” such as those typically used in educational lectures and commercial sales and training settings, and in particular to remote whiteboards. As will become clear, however, the application of the present invention is not restricted to whiteboards exclusively, but can work with any Writing Surface suitable for image acquisition (e.g., flipcharts or paper on a desk). Receive-only sites may participate in the remote presentation without contributing Local Markings to the composite. The present invention is compatible with conventional software products which will carry audio and other data streams on the same channel as the compressed image signals.

摘要： Disclosed herein are representative embodiments of methods, systems, and apparatus for performing synthesis. For example, in one exemplary method disclosed herein, a high-level description of a complete circuit design is partitioned into a plurality of sections. Two or more synthesis engine configurations are selected for a respective one of the sections. The respective one of the sections is synthesized using the two or more selected synthesis engine configurations, thereby generating two or more gate-level descriptions. A gate-level description of the complete circuit design is generated that includes at least a portion of one of the gate-level descriptions. Computer-readable media storing instructions for causing a computer to perform any of the disclosed methods are also disclosed herein.

摘要： An interactive projected image video display system which includes a computer for generating video images, a projection apparatus coupled to the video output port of the computer for projecting computer-generated video images onto a projection screen, and at least one video camera for visually recording the projected image. The computer includes a frame grabber board coupled to the video camera for capturing individual frames or series of frames from the video recording of projected image. The captured images are compared to the computer generated images to detect for the presence of recognizable features introduced onto the projected image by a user to instruct the computer to trigger a computer operation. The system can also simulates a mouse to be used with any off the shelf application that uses a regular mouse.
