Patents Assigned to Sirchie Finger Print Laboratories
  • Patent number: 5057019
    Abstract: A process for creating a facial identification data base using a digital data processing computer system is provided. Entire photographic images of persons are first displayed and picked up by charge coupled solid state image sensors in a camera to produce electrical signals corresponding to the facial images. The sensors are horizontally and vertically disposed within the camera. The electrical signals are serially applied from the sensors to the computer system, where they are digitized and displayed onto the graphics monitor screen. Specific parameters relating to portions of the partial images to be stored are then inserted into the computer. The parameter data is then used to produce partial digitized images representing specific areas of said entire facial images, such as the forehead, nose, mouth or chin. The partial digitized images are produced by masking other areas of the total digitized image.
