Patent Images

1. An interactive image processing method comprising the steps of preparing image characteristics of objects to be identified from entire image areas and procedures having steps and/or parameters for extracting an object, wherein each procedure includes steps for effecting at least spatial filtering, binarization and a binary-image processing;

  • selecting a corresponding one of said procedures for extracting a respective object by comparing an image characteristic of an externally applied input image with the corresponding prepared image characteristics; and

    making an external inquiry for inputting the image characteristic of the input image so as to effect in at least an alternative selection from combinations of different ones of said procedure steps as to the appropriate object extraction procedure from said prepared procedures, wherein said method further comprising the steps of;

    designating a limited area on a display having substantially uniform characteristics from an input image of multiple gray levels and containing at least an object to be identified and a corresponding background area;

    extracting information related to the image characteristics from said object and the corresponding background area representing said designated limited area;

    evaluating the input image characteristics in accordance with said extracted information and a corresponding one of said prepared procedures for image evaluation of said object; and

    determining said object extraction procedure from the input image characteristics based on a combination of an interactive response to said inquiry and the result of said image characteristic evaluation.
