  • Patent number: 6633648
    Abstract: The invention is a method of creating an enlarged listening sweet spot for multiloudspeaker audio reproduction. The method employs a plurality of audio drivers displaced generally in a horizontal dimension for a vertically oriented head of a listener, the drivers operating over a plurality of different passbands. Higher frequency drivers are located closer to one another and displaced more towards a center line of the listening space than lower frequency drivers, thereby causing a smaller change in acoustic ear signals for listeners seated away from the designed-for listening position, but without causing increased low frequency signal capacity requirements for phantom images generally outside the array. Specially adapted signal processing accounting for the layout of the various drivers and their associated crossover networks is employed to create desired audio images.

  • Patent number: 6633654
    Abstract: A perceptual model performs an analysis of a media signal, such as an image or audio signal. The model may be used in media signal processing applications such as digital watermarking and data compression to reduce perceptibility of changes made to code the signal. For image applications, the model computes the sensitivity of an image to changes based upon local image contrast, while taking into account the sensitivity of connected directional edges. By comparing the local image strength of various directionally filtered versions of the image, the model creates a directional control vector. This control vector may be used to reduce changes to an image in text and edge regions, and thus, avoid perceptible artifacts in those regions. The model takes into account the local contrast of the image and the directional control vector to create a gain vector. Using the local contrast measurements, the model follows the eye's nonlinear response to contrast discrimination.

  • Patent number: 6633662
    Abstract: Detection of fetal nucleated red blood cells (NRBCs) is achieved by employing a combination of brightfield and fluorescence images of nuclear and cytoplasmic markers. The brightfield and fluorescence images are all obtained with a single multi-bandpass dichroic mirror. The objects in the sample are stained with a fluorescent dye that selectively stains nuclei and a dye that selectively stains fetal hemoglobin in the cytoplasm of fetal RBCs. UV excitation provides fluorescent emissions from the stained cell nuclei and visible illumination provides brightfield transmission of light that is absorbed by the stained cytoplasm. The images are processed to determine regions where the fluorescent emissions by cell nuclei in response to the UV excitation and the absorption by fetal hemoglobin of the brightfield illumination overlap or are in close proximity.

  • Patent number: 6633665
    Abstract: This invention provides a method to transform 3D object points onto 2D image points for linear pushbroom images. The problem is decomposed to the problem of finding sensor line coordinates and the problem of finding sensor column coordinates from linear pushbroom collinearity equations. The procedures to solve the problem are as follows. First, assume an initial value for image line coordinate to be sought for and using this value, calculate the sensor attitude. Next, assume the sensor attitude is constant and calculate a new image line coordinate satisfying linear pushbroom collinearity equations. Next, update the initial value with the image line coordinate calculated and continue the procedures until the difference between an initial value and a new value calculated becomes smaller than a threshold. If the different between an initial value and calculated value is smaller than a threshold, accept the calculated value as the sensor line coordinate.

  • Patent number: 6633667
    Abstract: A process that prepares inverse conversion data in advance, and inversely converts a signal in a given color space into that in an original color space suffers conversion accuracy variations depending on the spatial intervals of color signals upon preparing the inverse conversion data, requires high cost for inverse conversion in terms of time, resulting in poor efficiency. When an input signal in the Lab color space is converted into an output signal in the RGB color space, a color signal converter (102) converts an input signal in the RGB color space into a signal in the Lab color space. A potential calculator (103) extracts the difference between the input signal and the color signal output from the color signal converter (102). A minimal potential search unit 104 searches for a signal to be supplied to the color signal converter (102), which makes the extracted difference minimal, and outputs the search result as a color signal in the RGB color space, i.e., the conversion result.

  • Patent number: 6633670
    Abstract: To improve compression efficiency and decompressed image quality, images are decomposed into separate layers each containing a limited number of image element types (text, line art, or photographic). Each layer can then be compressed separately with a process that is optimal for the type of image element included in the layer. Images are decomposed into foreground, background, and mask layers. The value of a pixel in the mask layer designates whether the spatially corresponding pixel of the recomposed image will be selected from the spatially corresponding pixels of either the foreground or the background layer. The present invention provides a method of determining the value of a pixel for a mask layer. The image is partitioned into large and small sub-images or blocks. A sub-image mask is created for each sub-image by sorting pixels of the sub-image into clusters centered on the luminance of pixels of a pair of pixels of maximum luminance gradient.
