摘要： A method and apparatus for compressing facsimile documents based on arithmetic coding. A combination of one-dimensional and two-dimensional arithmetic coding is employed to ensure that the effect of a transmission error is not propagated to the whole document. Appropriate contexts for the probabilistic models associated with arithmetic coding for one and two dimensional cases are presented. An error detection scheme to identify the presence of transmission errors is also presented.

摘要： The disclosed invention is a enhancement to the Video Encoder component of the MPEG standard to improve both the efficiency and quality of the video presentation at the display device. The inventions described below pertain to the enhancement of video compression technology. In general, they are compatible with MPEG video standards (as in current art), but represent novel enhancements thereof. The above inventions apply to several transmission media and networks including cable, DSL, wireless, satellite and IP networks. Another category of invention in this disclosure enhances networking performance by recognizing that the transmitted information is video, rather than data. This invention can be scaled to other classes of multimedia data such as speech or audio or images.

摘要： The invention determines the degree of similarity between a target image and each of a plurality of reference images. The measure used for the degree of similarity between images is based on the human perceptive system, so that images that appear to a human to be similar in color have a higher similarity measure than images that appear to a human to be dissimilar in color. Each of the most populous colors of each partition of the target image is associated with a color in a corresponding partition of the reference image that is closest to the target image color. The similarity measure is based on the number of occurrences of each of these associated colors in the corresponding partitions, as well as the color difference between these associated colors. Thus, images that have similar, albeit not identical, colors, will have a higher similarity measure than images that have dissimilar colors. In a preferred embodiment, color difference is determined based upon the CIE luminance-chrominance color space. Also, in a preferred embodiment, the target image color is quantized into a set of discrete colors that are based upon the predominant colors in the reference images.

摘要： A reconfigurable multi-media system, method and device provides monitoring and reconfiguration of a plurality of communication layers of a communications stack to dynamically reconfigure the modulation and coding of software defined radio (SDR). The system includes a software object radio (SWR) library having reconfigurable object specification, design and performance parameters, the SWR is adapted for at least one of transmitting and receiving multi-media content via wireless communication; a controller in communication with the SWR library; a power management device module in communication with said controller; a reconfigurable encoder/decoder in communication with said controller to provide the SWR with dynamic coding information for modulation; a TCP/IP interface in communication with said reconfigurable encoder/decoder and said controller; and an application layer comprising a link layer and a reconfigurable physical layer in communication with each other and said controller, the physical layer adapted for communication with a channel, and the application layer including at least one driver for multi-media delivery. The controller monitors the physical layer and link layer information and the reconfigurable encoder/decoder dynamically reconfigures modulation and coding of multi-media content according to a cross-layer optimization approach.

摘要： The system builds a database which stores data corresponding to a plurality of images. To begin, the system divides each image into N (N≧1) regions. Then, for each of the N regions, the system calculates a histogram of the region, generates a binary representation of the histogram, and stores data corresponding to the image in a binary tree based on the binary representation. The database may then be used to determine images which are similar to a query image. To do this, the system divides the query image into N regions, each of which corresponds to one of the binary trees in the database. Data corresponding to one or more images in the database is then retrieved from the binary trees based on the N regions. The system then determines which of these images is similar to the query image based on the retrieved data.
