A remote controlled robot with a head that supports a monitor and is coupled to a mobile platform. The mobile robot also includes an auxiliary camera coupled to the mobile platform by a boom. The mobile robot is controlled by a remote control station. By way of example, the robot can be remotely moved about an operating room. The auxiliary camera extends from the boom so that it provides a relatively close view of a patient or other item in the room. An assistant in the operating room may move the boom and the camera. The boom may be connected to a robot head that can be remotely moved by the remote control station.

Devices, methods, and software are disclosed for an adaptive video capture decode system that efficiently manages a stream of image frames between a device display screen and a processor performing decode attempts on decodable features in the image frames. In an illustrative embodiment, a device assigns frames of image data from a stream of frames of image data to either a display subsystem or a decode subsystem. The display subsystem is operative for rendering the frames of image data on a display screen. The decode subsystem is operative for receiving frames of image data and performing an attempted decode of a decodable indicia represented in at least one of the frames of image data. None of the frames of data are assigned to both the display subsystem and the decode subsystem.

A color mapping process enhances a watermark by computing a change in colors that is less visible for a given watermark strength. The mapping process provides smooth transitions from one color region to another, and may be implemented efficiently with a 3D look up table. A user interface scheme enables the user to control encoding of the watermark in desired color regions.

An apparatus and method for allowing multiple high and low resolution SBI and conventional FPA imaging devices to use a common high resolution monitor and archive device without increasing or significantly changing the footprint of existing devices. This system and method uses a frame grabber for digitizing video from the legacy FPA devices, a frame mapper for rendering or mapping the FPA video into the SBI digital format, a converter for rasterizing SBI data streams into pixel-oriented FPA video frames, an input selector for selecting which FPA or SBI imaging device to display on a high resolution monitor, an processor for storing and manipulating frames of video, a video output encoder for converting the SBI frames into a video signal appropriate for display on the high resolution monitor, and an output means for connecting to a storage device for archiving video and images.

The automatic call distribution center of the present invention uses a multimedia automatic call distribution server acting as connection manager for data network callers and provides for automatic caller identification.

A moving image brightness variation compensation method for encoding digital moving images for transmission and storage, and for image processing when editing moving images, the moving image brightness variation compensation method comprising a step of compensating for overall brightness variations by correcting a luminance value x of each pixel according to the formula DC.x+DB, wherein DB is a parameter indicating a gain change and DC is a parameter indicating a contrast change, the parameters representing overall luminance changes between a reference image plane and an image plane being processed.

A foveated imaging system, which can be implemented on a general purpose computer and greatly reduces the transmission bandwidth of images has been developed. This system has demonstrated that significant reductions in bandwidth can be achieved while still maintaining access to high detail at any point in an image. The system is implemented with conventional computer, display, and camera hardware. It utilizes novel algorithms for image coding and decoding that are superior both in degree of compression and in perceived image quality and is more flexible and adaptable to different bandwidth requirements and communications applications than previous systems. The system utilizes novel methods of incorporating human perceptual properties into the coding the decoding algorithms providing superior foveation. One version of the system includes a simple, inexpensive, parallel pipeline architecture, which enhances the capability for conventional and foveated data compression. Included are novel applications of foveated imaging in the transmission of pre-recorded video (without eye tracking), and in the use of alternate pointing devices for foveation.

A method for head pose estimation may include receiving block motion vectors for a frame of video from a block motion estimator, selecting at least one block for analysis, determining an average motion vector for the at least one selected block, combining the average motion vectors over time (all past frames of video) to determine an accumulated average motion vector, estimating the orientation of a user's head in the video frame based on the accumulated average motion vector, and outputting at least one parameter indicative of the estimated orientation.

A method for effectively implementing a multi-room television system includes a digital base station that processes and combines various program sources to produce a processed stream. A communications processor then responsively transmits the processed stream as a local composite output stream to various wired and wireless display devices for flexible viewing at variable remote locations. The transmission path performance is used to determine the video encoding process, and special attention is taken to assure that all users have low-latency interactive capabilities.

A fully digital camera system provides high-resolution still image and streaming video signals via a network to a centralized, server supported security and surveillance system. The digital camera for collects an image from one or more image transducers, compressing the image and sending the compressed digital image signal to a receiving station over a digital network. A plurality of image transducers or sensors may be included in a single camera unit, providing array imaging such as full 360 degree panoramic imaging, universal or spherical imaging and field imaging by stacking or arranging the sensors in an array. The multiple images are then compressed and merged at the camera in the desired format to permit transmission of the least amount of data to accomplish the desired image transmission. The camera also employs, or connects to, a variety of sensors other than the traditional image sensor. Sensors for fire, smoke, sound, glass breakage, motion, panic buttons, and the like, may be embedded in or connected to the camera. Data captured by these sensors may be digitized, compressed, and networked to detect notable conditions. An internal microphone and associated signal processing system may be equipped with suitable signal processing algorithms for the purpose of detecting suitable acoustic events and their location. In addition, the camera is equipped with a pair of externally accessible terminals where an external sensor may be connected. In addition, the camera may be equipped with a short-range receiver that may detect the activation of a wireless ‘panic button’ carried by facility personnel. This ‘panic button’ may employ infrared, radio frequency (RF), ultrasonic, or other suitable methods to activate the camera's receiver.
