    摘要: What is disclosed is a novel system and method for pixel and object level neutral detection. In one embodiment, an image is scanned into a plurality of pixels. A local pixel of interest is identified along with a neighborhood of pixels around the local pixel. The chroma value of the current pixel as well as the average local chroma of the neighborhood are calculated. An adjusted chroma is determined based on the average local chroma. A luminance value can also be measured for the current pixel and for each of the neighbor pixels and a luminance variation determined. The adjusted chroma can be further modified based on the determined luminance variation. The adjusted chroma is compared against a threshold to determine a neutral pixel detection tag for the current pixel. The pixel tags can be utilized to control an adjustment of pixels in a device independent L*a*b* or CMYK domain.

    摘要: What is provided herein is a novel system and method for estimating the amount of color in a document to be printed, with the capability to handle composite black, in those environments without access to all the original four color planes simultaneously. In one embodiment, input CMYK values are pre-adjusted via a look-up table to take into account the neutral balance characteristics. The planes are then scaled and quantized so that all four planes become available simultaneously. The difference among the quantized CMYK color values is compared against a threshold that is input level dependent. A pixel is classified into one of several color categories such as, for example, true neutral, fuzzy neutral, true color or fuzzy color. A color billing strategy can then be automatically determined based on the amount of color content. The method advantageously provides flexibility to support multi-tier billing in systems with various marking technologies.

    摘要: A document size identification module receives a single scan of a document and detects for at least one of a black to white transition and a white to black transition. The black to white transition may represent a transition from an overscan area of a platen to a document. The white to black transition may represent a transition from the document to the overscan area of the platen. By detecting at least one of the black to white transition and the white to black transition, the document width may be determined. By determining the document width, the document size may be identified.

    摘要: An original image is received in a red-green-blue color space. Pixels in the original image are converted to a luminance-chrominance color space. Background pixels in the original image are determined by comparing a luminance value of each pixel to a selectable luminance threshold, and comparing chrominance value of each pixel to a predetermined chrominance threshold. Chrominance values of the background pixels in each chrominance channel are adjusted.
