  • Patent number: 4261043
    Abstract: In a data compression system utilizing the Haar, Walsh or Hadamard transformation, a machine which operates in the transform domain to obtain approximations to the higher order transform coefficients by means of extrapolation from lower order transform coefficients. The extrapolation of the higher order transform coefficients is approximately equivalent to either a linear or to a quadratic interpolation within the spatial or time domain.

  • Patent number: 4213150
    Abstract: A digital machine for detecting and processing pictorial edges in video data. The invention mechanizes, in parallel, three different processing techniques, the outputs of which are combined in a selectable manner to generate processed and enhanced video data. The first parallel processor convolves four inter-related 3.times.3-element masks with the 2-dimensional video input data to locate the pictorial edges, to determine the edge directions, to execute edge connectivity logic, and to calculate certain edge statistics. The second parallel processor implements a 3.times.3 element, low or high pass image filter, and an adaptive threshold filter. Both the first and the second parallel processors use Fast-Form algorithms which allow data processing in real time with a minimum of components. The third parallel processor operates on the video data in serial form to generate the video output from the edge processing unit.
