摘要： A technique for hiding of data, including watermarks, in human-perceptible sounds, that is, audio host data, is disclosed. In one embodiment a method comprises three steps. In the first step, data to be embedded is inputted. In the case of a watermark, this data is a unique signature, and may be a pseudo-noise (PN) code. In the case of hidden data to be embedded in the host data, this data is the hidden data itself, or the hidden data as spread against the frequency spectrum by a pseudo-noise (PN) code. In the second step, the inputted data is embedded within the host data, in accordance with a perceptual mask of the host data. The perceptual mask determines the optimal locations within the host data to insert the inputted data. In the case of sounds, these optimal locations are determined by reference to the human auditory system. In the third step, the host data, with the embedded data, is further masked by a non-frequency mask. In the case of audio data, the non-frequency mask is a temporal mask.

摘要： A method and apparatus for digital watermarking to resolve multiple claims of ownership is disclosed. According to one embodiment of the invention, a first watermark requiring the host data for detection is embedded into the host data. A second watermark is also embedded into the host data. According to another embodiment of the invention, a pseudo-random sequence acting as a watermark is generated based on two random keys. One of the two random keys is related to the author of the host data into which the watermark is to be embedded, whereas the other of the two random keys is dependent on the host data itself.

摘要： A method and apparatus for the watermarking of video data is disclosed. In one embodiment, discrete objects are extracted from the video host data. Each is assigned and embedded with a watermark. The watermark is embedded by generating the watermark, applying it to a perceptual mask of the block, spatially masking the resulting block, and re-adding the block to the result. The objects are collected into a database so that an object may be tracked as it is transformed from frame to frame of the video host data.

摘要： A method and apparatus for the scene-based watermarking of video data is disclosed. In one embodiment, each of a number of frames of a scene of video host data undergoes a temporal wavelet transform, from which blocks are extracted. The blocks undergo perceptual masking in the frequency domain, such that a watermark is embedded therein. Once the watermark block is taken out of the frequency domain, a spatial mask of the original block is weighted to the watermark block, and added to the original block to obtain the watermarked block.

摘要： A computerized image and document management system for tent-based retrieval integrating content-based retrieval support directly into the compressed files. The system minimizes a weighted sum of the expected size of the compressed files and the expected query response time. Object searching of documents stored by the system is possible on a scalable resolution basis. The system includes a novel object representation based on embedded prototypes that provides for high-quality browsing of retrieval images at low bit rates.

摘要： Techniques are described for analyzing auscultatory sounds to aid a medical professional in diagnosing physiological conditions of a patient. A data analysis system, for example, applies singular value decomposition to auscultatory sounds associated known physiological conditions to define a set of one or more disease regions within a multidimensional space. A diagnostic device, such as an electronic stethoscope or personal digital assistant, applies configuration data from the data analysis system to generate a set of one or more vectors within the multidimensional space representative of auscultatory sounds associated with a patient. The diagnostic device outputs a diagnostic message associated with a physiological condition of the patient based on the orientation of the vectors relative to the disease regions within the multidimensional space.

摘要： System and methods include transmitting the same signal in all sub-bands in different time intervals and processing the corresponding received signals to achieve a time resolution proportional to the inverse of the whole bandwidth as opposed to that of a single sub-band. The systems and methods refine the coarse resolution that is achieved by conventional approaches, such as the correlation method, in a single sub-band by aligning the outputs of the matched filters to the received signals from all sub-bands and applying a fast Fourier Transform (FFT) in each time bin along the sub-band index.
