  • Patent number: 6898326
    Abstract: A transformation unit 102 transforms an entered image to multi-resolution space. A quantizer 105 performs vector quantization on a local pattern of an image of a multi-resolution representation. A perspective-order calculating unit 107 extracts a plurality of code words, positions corresponding thereto and/or angle of rotation and/or scale, and the perspective-order relationship of a plurality of these representative vectors, from the quantized image. An algebraic encoder 108 encodes the input image based upon the extracted information. As a result, there are provided an image processing apparatus and method for asymmetric encoding without motion in three dimensions and extraction of a three-dimensional structure. Further, a transformation unit 1103 transforms an entered image to vector field, and a singularity detector 1104 detects a singularity in the transformed image.

  • Patent number: 6853331
    Abstract: A method of compensating for atmospheric effects to detect the actual location of low elevation objects using near horizon radar to detect an object which utilizes a preexisting satellite structured to send a signal indicating the position and velocity of said satellite, wherein the location of the satellite is known. The method includes a step of providing a radar site, a first receiver structured to receive a signal from the satellite indicating an apparent location of the satellite, and a second receiver, located at a distance from the radar site, structured to receive the satellite signal and which indicates the observed location of the satellite. The first receiver is utilized to receive a signal from the satellite when the satellite is at a low elevation. This signal indicates the apparent location and velocity of the satellite.

  • Patent number: 4247180
    Abstract: An improved motion picture apparatus for use with a card-like film unit and being of the type including a rotatable barrel cam for reciprocally driving the optical output end of a pivoting periscope boom, forming part of a scanning optical system, stepwise along a given locus over a row of sequential image positions at the film plane wherein the improvement comprises structure for axially displacing the barrel cam to adjust the location of the given locus so that at each of the steps the output end is in registration with a corresponding one of the image positions.

  • Patent number: 4084892
    Abstract: A control for varying the speed of advancement of film is described for use in a film projector in which the film is advanced by a shuttle tooth which engages perforations in the film and advances the film along a path between a light source and a projector aperture. The control includes a rotary shutter assembly having one or more shutter blades for interrupting the light from the light source. As the shutter assembly rotates, the shuttle tooth is reciprocated in the direction of film feed by a rotary cam having one or more cam lobes mechanically coupled to the shuttle tooth. The rotation of the cam lobes is synchronized to the rotation of the shutter blades such that the shuttle tooth is positioned for engagement with the perforations associated with the next successive film frame to be projected whenever a shutter blade interrupts the light source.
