  • Publication number: 20140104395
    Abstract: Methods of and systems for three-dimensional digital impression and visualization of objects through an elastomer are disclosed. A method of estimating optical correction parameters for an imaging system include pressing an object of known surface topography against an elastomer and imaging a plurality of views of the surface topography of the object through the elastomer. The method also includes estimating a three-dimensional model of the object based on the plurality of views and estimating optical correction parameters based on a known surface topography of the object and the estimated three-dimensional model. The optical correction parameters correct distortions in the estimated three-dimensional model to better match the known surface topography.

  • Patent number: 8411140
    Abstract: A tactile sensor includes a photosensing structure, a volume of elastomer capable of transmitting an image, and a reflective skin covering the volume of elastomer. The reflective skin is illuminated through the volume of elastomer by one or more light sources, and has particles that reflect light incident on the reflective skin from within the volume of elastomer. The reflective skin is geometrically altered in response to pressure applied by an entity touching the reflective skin, the geometrical alteration causing localized changes in the surface normal of the skin and associated localized changes in the amount of light reflected from the reflective skin in the direction of the photosensing structure. The photosensing structure receives a portion of the reflected light in the form of an image, the image indicating one or more features of the entity producing the pressure.

  • Patent number: 5818972
    Abstract: A system for, and method of, enhancing a digitized image signal according to a helper signal architecture are described. The architecture includes an analysis filter, responsive to a digitized image signal, for filtering the digitized image signal, corresponding to a first frequency band, to produce a first frequency band signal. The first frequency band signal is then applied to a point operator, which modifies the first frequency band signal in accordance with a non-linear characteristic. The non-linear characteristic includes a first region having a negative slope for low amplitude input signals. The non-linearity further includes a second region having a positive slope for informational components of an input signal so that informational components of the first frequency band signal cause the point operator to produce a modified signal having components that relate to the input signal according to the positive slope.

  • Patent number: 5706417
    Abstract: A moving image representation format and encoding and decoding techniques. In the format, the image is represented as a series of layers, each layer comprising one or more maps containing information about the image. In decoding the information, the maps are combined in an order dictated by their ordinal depth in the image. Each layer comprises 1) an intensity map representing the intensity of the pixels in that layer, 2) an attenuation map by which the image intensities of the layers below it are multiplied while the intensity map corresponding to its layer is multiplied by its complement, 3) a delta map that describes the temporal derivative of the points in the corresponding intensity map, and 4) a velocity map which describes how all points in the layer are warped over time.

  • Patent number: 5557684
    Abstract: A system stores images as a series of layers by determining (i) the boundaries of regions of coherent motion over the entire image, or frame, sequence; and (ii) associated motion parameters, or coefficients of motion equations, that describe the transformations of the regions from frame to frame. The system first estimates motion locally, by determining the movements within small neighborhoods of pixels from one image frame i to the next image frame i+1, to develop an optical flow, or dense motion, model of the image. Next, the system estimates the motion using affine or other low order, smooth transformations within a set of regions which the system has previously identified as having coherent motion, i.e., identified by analyzing the motions in the frames i-1 and i. It groups, or clusters, similar motion models and iteratively produces an updated set of models for the image.

  • Patent number: 5526446
    Abstract: A technique is provided to remove noise from images and to enhance their visual appearance through the utilization of a technique which converts an image into a set of coefficients in a multi-scale image decomposition process, followed by modification of each coefficient based on its value and the value of coefficients of related orientation, position, or scale, which is in turn followed by a reconstruction or synthesis process to generate the enhanced image. Also contributing to the improved enhancement is a set of orientation tuned filters of a specialized design to permit steering, with the analysis and synthesis filters also having a self-inverting characteristic. Additionally, steerable pyramid architecture is used for image enhancement for the first time, with the steering being provided by the above orientation tuned filters.

  • Patent number: 5076687
    Abstract: An optical ranging apparatus is provided which resolves the depth of objects in an object field of a main lens. Light is directed by the main lens to a lenticular array consisting of an array of lenticules each of which generates an image of the lens surface. Each of the generated images is directed to a photodetector array divided into macropixels each of which receives one of the lenticule images. Each macropixel is made up of a number of subpixels, each of which is a discrete photodetector element and generates an electrical signal proportional to the intensity of light upon it. A data processor receives the signals from the subpixels and assembles subimages, each of which consists of one subpixel from each macropixel. Each subimage represents a view of the entire object field through one portion of the main lens. The data processor determines depth of objects in the object field by comparing the parallax between subimages.

  • Patent number: 5003377
    Abstract: Methods and systems for adding additional information to broadcast motion picture signals so that an advanced receiver can decode that information to provide improved picture quality, while a standard receiver will display an image with minimally visible impairments. In particular, chrominance information can be generated at a fraction of the frame rate and the alternate frames then used to encode additional data, such as high definition luminance information in the chrominance signal.

  • Patent number: 4965442
    Abstract: A range camera is provided for the determination of range to an object through the utilization of a system which projects a limited depth of field light pattern onto an object and measures the blurring of the pattern on the object. In one embodiment an anisotropic aperture or astigmatic optics are used in combination with an isotropic pattern to eliminate system error introduced by the camera. The anisotropic aperture provides that blurring takes place only in a given direction, with measurement of blurring in an orthogonal direction providing an output only responsive to the blurring associated with the camera. This blurring can then be subtracted out to eliminate system error from the range measurement. The range camera is operative to produce a range picture or map, with optional outputs providing localized albedo and a conventional brightness image.
