    摘要： A transmitter in an optical communications system includes a digital signal processor for processing a data signal to generate a sample stream encoding successive symbols in accordance with a constrained phase modulation scheme having a constellation of at least two symbols and a modulation phase constrained to a phase range spanning less than 4π. A digital-to-analog converter converts the sample stream into a corresponding analog drive signal. A finite range phase modulator modulates a phase of a continuous wavelength channel light in accordance with the analog drive signal, to generate a modulated channel light for transmission through the optical communications system. A receiver in the optical communications system includes an optical stage for detecting phase and amplitude of the modulated channel light and for generating a corresponding sample stream, and a digital signal processor for processing the sample stream to estimate each successive symbol of the modulated channel light.

    摘要： A system for improved display of tuned multi-scaled regions of an image with local and global control and methods for making and using same. To assist the novice user of image processing tool, less input parameters should be required. Further, it will assist the user if results are diplayed in a shorter period of time. Utilizing a hierarchical bottom-up approach provides for the advantage of being able to utilize intermediate results to gather more details. The systems and methods disclosed provide for the grouping of contiguous pixels which have similar properties. Further, the disclosed embodiments provide for the user the ability to see all levels of detail of segmentation either globally or locally. The scale-space is tuned to the information in the image.

    摘要： Systems and methods for processing an initial digital image that comprises a foreground object and a background are provided in which the initial image is displayed on a display. A plurality of instances of an image segmentation technique are performed to the initial image, where the segmentation technique differentiates between the foreground object and the background in the initial image, thereby creating a plurality of processed images of the initial image. A first instance of the image segmentation technique uses a different parameter set than a second instance of the image segmentation technique. Each respective instance of the image segmentation technique creates a processed image corresponding to the respective instance of the image segmentation technique. Each such processed image is concurrently displayed at a time when the initial image is also displayed. A selection of a processed image in the plurality of processed images is then received for further processing.

    摘要： A gold code generator is described comprising two pairs of linear feedback shift registers, the seed values for the second pair of linear feedback shift registers are different from the seed values for the first pair of linear feedback shift registers. The second seed values are calculated from the first seed values. The use of this second pair of linear feedback shift registers prevents the need to use a wide span of taps to the linear feedback shift register to produce output bits. By using two pairs of linear feedback shift registers, a parallel output implementation can be produced in which multiple output bits are produced in a single clock cycle.
