![Systems and methods for selective dithering using pixel classification](/abs-image/US/2007/03/29/US20070070427A1/abs.jpg.150x150.jpg)
Abstract:
A method of selective dithering for enhancing the printability of an image, including receiving input pixels of an original input image and identifying the pixel classification of the input pixels, where the pixel classification characterizes each of the plurality of pixels based, at least in part, on their respective gray values. Thereafter, a dither input is added to at least some of the input pixels to generate a filtered and dithered image, where the strength of the dither input applied to generate the filtered and dithered image is based on the pixel classification. Full dither may be applied for smooth pixels, and little or no dither may be applied for edge pixels.
