Abstract: Image processing techniques which involve direct manipulation of the compressed domain representation of an image to achieve the desired spatial domain processing without having to go through a complete decompression and compression process. The techniques include processing approaches for performing the eight operations in D4 (the dihedral group of symmetries of a square) on JPEG images using the discrete cosine transform (DCT) domain representation of the images directly. For a task such as image rotation by 90° (an operation in D4), DCT-domain based methods can yield nearly a five-fold increase in speed over a spatial-domain based technique. These simple compressed-domain based processing techniques are well suited to the imaging tasks that are needed in a JPEG-based digital still-camera system.

Abstract: A fiber optic detection system in which a single optic fiber has a U-shaped configuration. A source of light is disposed at one upper free end of the optic fiber and a light detector is disposed at the other upper free end of the optic fiber. At the bottom of the optic fiber is a light variable loop adapted to be disposed in various media, such as liquids, fluids and air. The light from the source of light is conducted from the source of light through the optic fiber and to the light detector. The quantum of light lost as the light travels through the light variable loop will depend on the medium or the concentration of the medium in which the light variable loop is disposed. The light detector detects the light advancing thereto to produce a signal representative of the medium or the concentration of the medium in which the light variable loop is disposed. An electronic circuit with a microprocessor is responsive to the signal produced by the light detector for determining the medium or the concentration of the medium in which the light variable loop is disposed.

Abstract: A computer (host), which is communicating with an interactive whiteboard projector (client) through a remote desktop connection, launches third-party applications supporting multiple mice (i.e. drawing pens) and provides these applications with virtual mouse device and input event signals for each pen device connected on the projector. The applications will behave as if the host system were configured with multiple installed mice, though no added driver or physical connected hardware is present.

Abstract: A system for establishing a remote desktop connection between a client projector and a host computer, the client projector and the host computer being connected by a network. A private remote desktop service virtual channel is established between the host computer and the client projector. In the client projector, a processor initiates a remote desktop connection process, and completes a remote desktop connection to the host computer. The client projector receives keyboard and mouse events from the host computer across the private remote desktop service virtual channel. The keyboard or mouse events received by the client projector are injected into an operating system of the client projector. They are interpreted by a client application remote desktop connection as a valid input device event, and forwarded to the host computer to actuate a graphical user interface of a remote desktop session.

Abstract: Methods and systems are disclosed for processing image frames to reduce the bandwidth requirements. Embodiment of the present invention may include mode-specific image frame rendering in photorealistic and non-photorealistic modes, such as outline and cartoon modes. In embodiments, update regions may be identified and reduced by an edge position mask. In embodiments, update regions may be bounded by rectangles and such regions may be reduced in number by merging regions together using various no-cost or cost approaches. To improve compressibility, regions to be transmitted that do not require updating at the receiver may be encoded as transparent.
