  • Raster-order pixel dithering
    Patent number: 7978200
    Abstract: Stochastic dithering may be used to reduce the size of the frame buffer and the complexity of the D/A Converters (DACs) in the drive circuitry that are used in a video display system. Hardware for stochastic dithering can be simplified when pixel data is presented in raster order. The hardware adds algebraic noise to the image to be dithered, and thresholds the result.

  • Unsupervised color image segmentation by dynamic color gradient thresholding
    Patent number: 7873214
    Abstract: A method for segmenting an image includes computing a color gradient map based on an inputted image and selecting at least one initial seed of at least one pixel based on the color gradient map. The method further includes growing a region of pixels adjacent to the initial seed and merging adjacent regions of pixels using a measure of similarity.
