In digital recording, audio signals picked up by a microphone or other transducer or video signals picked up by a camera or similar device are converted into a stream of discrete numbers, representing the changes over time in air pressure for audio, and chroma and luminance values for video, then recorded to a storage device. To play back a digital sound recording, the numbers are retrieved and converted back into their original analog waveforms so that they can be heard through a loudspeaker. To play back a digital video recording, the numbers are retrieved and converted back into their original analog waveforms so that they can be viewed on a video monitor, television or other display.

Spatio-Temporal Light Field Cameras

Spatio-temporal light field cameras that can be used to capture the light field within its spatio temporally extended angular extent. Such cameras can be used to record 3D images, 2D images that can be computationally focused, or wide angle panoramic 2D images with relatively high spatial and directional resolutions. The light field cameras can be also be used as 2D / 3D switchable cameras with extended angular extent. The spatio-temporal aspects of the novel light field cameras allow them to capture and digitally record the intensity and color from multiple directional views within a wide angle. The inherent volumetric compactness of the light field cameras make it possible to embed in small mobile devices to capture either 3D images or computationally focusable 2D images. The inherent versatility of these light field cameras makes them suitable for multiple perspective light field capture for 3D movies and video recording applications.

Mobile digital video recording with pre-event recording

Provided is a mobile event-recording device that includes distributed elements within, attached to or otherwise mounted to a mobile vehicle, with the principal elements being: a first camera providing a real-time video signal that corresponds to an observed outboard live-motion scene; and a digital video recorder receiving the video signal provided by the camera and recording the video signal in response to a trigger signal (e.g., an activation switch for a light bar or siren, an air bag sensor signal indicating air bag deployment, or depression of an emergency button or a dedicated recording activation switch). The video recorder uses a buffer to receive and store the video signal so as to preserve the video signal during a programmable sliding (or rolling) time interval prior to the triggering event. Thus, in response to provision of the trigger signal, at least a portion of the video signal stored in the buffer is preserved for recording by the video recorder on a hard disk (or other long-term storage medium) and thereafter, the video recorder records directly on the hard disk (or other long-term storage medium).

High-resolution, three-dimensional whole body ultrasound imaging system

This invention incorporates the techniques of geophysical technology into medical imaging. Ultrasound waves are generated from multiple, simultaneous sources tuned for maximum penetration, resolution, and image quality. Digitally recorded reflections from throughout the body are combined into a file available for automated interpretation and wavelet attribute analyses. Unique points within the object are imaged from multiple positions for signal-to-noise enhancement and wavelet velocity determinations. This system describes gaining critical efficiencies by reducing equation variables to known quantities. Sources and receivers are locked in invariant, known positions. Statistically valid measurements of densities and wavelet velocities are combined with object models and initial parameter assumptions. This makes possible three-dimensional images for viewing manipulation, mathematical analyses, and detailed interpretation, even of the body in motion. The invention imposes a Cartesian coordinate system on the image of the object. This makes reference to any structure within the object repeatable and precise. Finally, the invention teaches how the recording and storing of the received signals from a whole body analysis makes a subsequent search for structures and details within the object possible without reexamining the object.

Method of restoring and reconstructing super-resolution image from low-resolution compressed image

InactiveUS20050019000A1Preserving contourRemove image blurImage enhancementTelevision system detailsDigital videoImage compression
Provided is a method of restoring and / or reconstructing a super-resolution image from low-resolution images compressed in a digital video recorder (DVR) environment. The present invention can remove a blur of a video sequence, caused by optical limitations due to a miniaturized camera of a digital video recorder monitoring system, a limitation of spatial resolution due to an insufficient number of pixels of a CCD / CMOS image sensor, and noises generated during image compression, transmission and storing processes, to restore high-frequency components of low-resolution images (for example, the face and appearance of a suspect or numbers of a number plate) to reconstruct a super-resolution image. Consequently, an interest part of a low-resolution image stored in the digital video recorder can be magnified to a high-resolution image later, and the effect of an expensive high-performance camera can be obtained from an inexpensive low-performance camera.

Method for video/audio recording using unrestricted pre-event/post-event buffering with multiple bit and frame rates buffer files

Aspects of the present invention include method and apparatuses that may be utilized to more efficiently use available storage space for a digital video recording system in a law enforcement vehicle and final “backend storage systems.” In one embodiment of the present invention, video and audio data is recorded in one or more buffers when a triggering event is activated, while a digital video recording device accounts for specified pre-event time, a time period before a first triggering event has been activated, and a post-event time, a time period after a second triggering event has been activated. The system will tag the actual start and stop points of events in one or more buffers based on a first and a second triggering event and will then include the pre-event and post-event data along with specified data. The system will then extract the event from one or more buffer files and write the event into final video files to be stored in a hard disk drive. By recording the pre-event and post-event data in multiple buffer files and extracting the final result from selected buffer files based on the nature of the event type, the system ensures that storage device is effectively used and, in this way, useful information is recorded.

Methods for embedding image, audio and video watermarks in digital data

A method for embedding an entire image, audio or video watermark sequence within another image, audio or video data sequence with minimum loss of data quality is presented. The method exploits the de-correlation property of data coefficients in the orthogonal transform domain, similar to the application in data compression through transform coding. The present invention describes the usage of a Discrete Cosine Transform as the embedding domain. However, other orthogonal transforms such as Fourier, Walsh-Hadamard, Haar, Sine and Wavelet can also be used for this operation. A unique key derived adaptively from spatial locations registering the thresholds of the ac transform energies is used to unlock or de-watermark the embedded image or audio sequence. Moreover, an exponential filter has been developed to compress and expand the watermark coefficients prior to the embedding and retrieval process. The method can be used in resolving multimedia copyright protection issues arising on the Internet and in the music industry, such as the inclusion of a company's logo or an artist's recorded voice. The method can also be incorporated as a built-in feature for digital recording devices, such as still and video cameras, as well as more recent devices such as VCD and DVD players. Moreover, the method can be applied to the commercial and service sectors, where security in transmission and reception of private information in terms of speech or image is of the utmost importance.

Standing order database search system and method for internet and internet application

An internet and / or intranet based database search system and method for conducting searches of highly confidential records such as individual patient medical records and to automate the process of securing required approvals to make such records available to a properly authorized and authenticated requesting party. The system's central premise is that the patient has a fundamental right to the confidentiality of their personal medical records and should control that right through specific, informed consent each time that a party requests to receive them. It reinforces the widely held conception of privacy in general as well as of the sanctity of the doctor / patient relationship by granting the doctor the right, subject to the patient's express permission, to initiate a search request. At the same time, it provides an expedited and cost-efficient means for transfer of such records as demanded by many healthcare reform proposals and gives the repositories where these records are held the right to stipulate the specific terms and conditions that must be fulfilled before they will release documents entrusted to their care, thereby substantially reducing the risk of litigation alleging breaches of patient confidentiality. And it carries out all of these legitimate interests in a way that is fast, simple to use and easy to audit. The system optionally includes a billing mechanism to pay for any added cost associated with providing this additional protection; and in its preferred embodiment, is applicable to both digital as well as non-digital records.
