    Abstract: A system and method of identifying a position of a crop row in a field, where an image of two or more crop rows is transmitted to a vision data processor. A preferential scan line profile in a search space about a candidate scan line profile is determined, and the candidate scan line profile is identified as a preferential scan line profile for estimating a position (e.g., peak variation) of one or more crop rows if a variation in the intensity level of the candidate scan line profile exceeds a threshold variation value. Alternatively, a position datum associated with a highest intensity value within the array of vector quantities can be selected as being indicative of a candidate position of a crop row. The candidate position is then identified as a preliminary row position if a variation in intensity level of the candidate scan line profile exceeds a threshold variation value.

If the transparent-type original is a negative film, then the adjustments of the transmitted light reading by the photoelectric transducer device are made respectively in the three primary colors independently of one another and, if the transparent-type original is a reversal film, then the adjustments of the transmitted light reading by the photoelectric transducer device are made uniformly in all of the three primary colors.

  • Patent number: 5687011
    Abstract: Digital signals are generated and stored for each pixel of a frame of a video originated material. A computer reads the digital signals and converts them to binary image data by employing a program to reassign color and black component values for each pixel. The component value reassignments performed by the computer are a primary component modification step. The primary component modification step, in one embodiment, comprises component modifications by selected image zones of the video originated images, based on color data within actual filmed images originated simultaneously as the video images. The film origination and video origination are preferably provided by the same camera, with image data delivered for both through the same lens by way of a "beam-splitter" device. The primary component modified digital data is assembled and a secondary modification may also be performed. Film stock emulsion grain patterns are introduced to the images in the second modification step.

  • Patent number: 5406326
    Abstract: Digital signals are generated and stored for each pixel of a frame of a preferably high definition video originated material. A computer reads the digital signals and converts them to binary image data by employing a selected look-up-table program to reassign color and black component values for each pixel. The programs applied in the component value reassignments are compiled from, and based on, comparative digital video component results of telecined film stocks' responses to selected color and grey scale gradients as charted against a selected video unit's response to the same charts under a selected number of identical lighting circumstances. A projector unit projects the high definition video frame through a macro lens onto a strip of exposed and processed motion picture or other photographic film of an optional grey scale gradient and thus grain pattern density.

  • Patent number: 5387929
    Abstract: A subject image being electronically transferred from a first medium to a second medium is accomplished through tone scale tracking. Three monochromatic channels representing the subject image are generated from the first medium. In a preferred embodiment, an image processing system provides color correction for each channel by compensating for film and video characteristics that cause a degradation of color from the original subject image. Calibration of the system is provided by means for an operator to specify tone densities for the second medium that correlate to signal levels derived from the first medium for each channel. The image processing system tracks the tone densities calibrated to provide enhanced film masking. The image processing system also performs characteristic curve processing in accordance with a Hurter-Driffield (HD) curve.

  • Patent number: RE38626
    Abstract: A video camera mounted on a parking enforcement patrol vehicle and connected to a computer near the operator. The system is driven along a patrol route where parked vehicles are governed by a posted time limit. The system enforces the local parking regulation by automatically determining whether or not each parked car has been parked longer than the posted time limit. Violations are detected by applying a License Plate Recognition algorithm to the images. Each license plate number is time-tagged, geo-referenced and entered into a local database. When the patrol vehicle re-traces the patrol route after the posted parking time limit has expired, the database is searched to flag vehicles that were observed at the same location during the previous circuit and therefore in violation of the parking regulations. When the system detects a parking violation, it prints a parking citation that the operator affixes to the offending parked vehicle.
