  • Determining pixels textual characteristics
    Patent number: 7616814
    Abstract: Pixels are classified as text; or “non-text” by responding to accumulated luminous brightness gradients within a predetermined pixel interior. Text and non-text image characteristics rest on estimating text-containing rectangles by determining a narrow width and a height of a peak in an interval of accumulated gradients around each pixel. The text characteristics also are inferred by detecting character corners by quantifying and smoothing gradient angles and by associating directional corner responses with each pixel.
    Type: Grant

  • Device for rapid defreezing of frozen or deep-frozen products
    Patent number: 4343979
    Abstract: Frozen or deep-frozen products transferred by a conveyor system within a furnace are subjected to radiation within the high-frequency or microwave range and to surface cooling which is carried out by electrostatic spraying of the products with cryogenic liquid consisting of liquid nitrogen or Freon R12.
