摘要： An edge finder for an image processing system locates edges in a digitized image over several different ranges of pixel values and assigns, to each pixel value an edge characteristic value which represents a minimum edge value for the pixel in the image. The exemplary edge finder that is able to resolve transitions occurring between two pixels or over groups of four or eight pixels to determine whether an edge should be defined between the original two pixels. The edge finder simultaneously examines four edges in two dimensions to determine the edgeness value for each pixel in the digitized image.

摘要： An image processing system encodes a natural image into a segmented or mosaic image having well-defined edges and a residual image. The segmented image is encoded using a lossless encoding technique while the residual image is encoded using a lossy technique. This encoded image may be recorded on a video tape such that the segmented image may be recovered in picture-in-shuttle modes such as fast forward and fast rewind. In addition, the recorded image may be decoded and reencoded through several generational levels without experiencing significant degradation in perceived image quality. The segmented image is produced by an encoder which employs a multi-scale edge finder that is able to resolve transitions occurring over two, four and eight pixels into an edge located between two pixels. In addition, the lossless encoder includes circuitry which chain-encodes the segmented image into a low-resolution image and multiple complementary images such that the low-resolution image may be stored as a single data packet and, thus, recovered as a unit from the tape in picture-in-shuttle mode.

摘要： Disclosed is a computer-based system and method for conducting ad hoc personal identification, or ID, transactions between at least two or more persons by means of a personal identification transaction apparatus attached to at least two communications channels. The personal identification transaction apparatus is intended to assist the interaction between two persons by brokering an identification transaction thus alleviating the exchange of detailed information necessary to confirm an identity, particularly that portion of a person's identity that is related to the purpose of the interaction between two persons. A component of the personal identification transaction apparatus includes a identification transaction order generation unit that provides a score associated with each user party to the transaction, as well as the transaction itself.

摘要： A chip multiprocessor (CMP) includes a plurality of processors disposed on a peripheral region of a chip. Each processor has (a) a dual datapath for executing instructions, (b) a compiler controlled register file (RF), coupled to the dual datapath, for loading/storing operands of an instruction, and (c) a compiler controlled local memory (LM), a portion of the LM disposed to a left of the dual datapath and another portion of the LM disposed to a right of the dual datapath, for loading/storing operands of an instruction. The CMP also has a shared main memory disposed at a central region of the chip, a crossbar system for coupling the shared main memory to each of the processors, and a first-in-first-out (FIFO) system for transferring operands of an instruction among multiple processors.
