  • Image segmentation apparatus and method
    Patent number: 6782129
    Abstract: A method and apparatus are provided for processing image data. A peak count and a valley count are determined within a window which includes a plurality of subwindows. An overall count is determined using the greater of the peak count and the valley count for each subwindow. The image data may then be classified based on this determination.

  • Image segmentation apparatus and method
    Patent number: 6529629
    Abstract: A method and apparatus are provided for classifying image data. A neighborhood average gray value may be determined for the input image data. A threshold value may then be determined based on the neighborhood average gray value. Pixels are evaluated to determine if a gray level difference between the pixel and the neighborhood average gray level is greater than the threshold.

  • Block level analysis of segmentation tags
    Patent number: 6516091
    Abstract: A system for processing segmentation tags to generate a block level tag representative of a group of segmentation tags. The system includes first and second statistic compilation circuits, each of the compilation circuits being connected to receive segmentation tags and compile a statistic for a plurality of the received segmentation tags. An address controller connected to the first and second statistic compilation circuits operates to select one of the first and second compilation circuits to receive the segmentation tags.

  • Image segmentation apparatus and method
    Patent number: 6389164
    Abstract: The present invention provides a method and apparatus for classifying image data. A video peak/valley counter may count peaks and valleys within a window of the input image data. The apparatus and method checks whether any peaks or valleys are located within a neighborhood of a pixel under consideration.

  • Image segmentation apparatus and method
    Patent number: 6360009
    Abstract: The present invention provides a method and apparatus for classifying image data. A white class detector may receive input image data and determine a white class of a specified pixel based on local roughness, peak or count or valley count and a brightness. A pattern detection device may detect a pattern of pixels across a scan line or matrix of input data and compare the pattern with a plurality of predetermined pixel patterns.

  • Image segmentation apparatus and method
    Patent number: 6272240
    Abstract: The present invention provides a method and apparatus for classifying image data. A video average may be determined from the image data. Peak detection may then be limited to an area within the image data where the video average is above a first threshold. Valley detection may be limited to an area where the video average is below a second threshold.
