    摘要: What is disclosed is a novel system and method for performing a CMYK to CMYKKpRGB color transform which helps reduce engine-specific halftone artifacts in diverse printing devices capable of dot-on-dot printing. The present method lends adaptive color overlapping control to local color regions depending on the engine behaviors and imaging artifacts to be addressed. With such a transform, an added degree of flexibility is provided to a variety of halftoning algorithms to reduce engine-specific halftone artifacts. Advantageously, increased halftone image quality is effectuated for different engine behaviors in a computationally efficient manner. Various embodiments have been disclosed.

    摘要: A microbial fuel cell for generating electricity. The microbial fuel cell includes an anode and a cathode electrically coupled to the anode. The anode is in contact with a first fluid including microorganisms capable of catalyzing the oxidation of ammonium. The anode is in contact with a second fluid including microorganisms capable of catalyzing the reduction of nitrite. The anode and the cathode may be housed in a single compartment, and the cathode may rotate with respect to the anode. The microbial fuel cell can be used to remove ammonium from wastewater, to generate electricity, or both.

    摘要: A method to determine the color status of a scanned original segments a binary halftone image into a predetermined number of local windows and converts each local window to a device-independent color space. The method then determines a color space parameter for each local window and compares the color space parameters for the local windows to at least one threshold to determine the color status of the scanned original. An apparatus having a scanner creates a scanned image of an original and has at least one processor to create a binary halftone image from the scanned image, segment the binary halftone image into a predetermined number of local windows, convert each local window to a device-independent color space, determine a color space parameter for each local window, and compare the color space parameter for each local window to at least one threshold to determine the color status for the scanned original.

    摘要: A method of gray component replacement receives a current pixel color value. A highlight likelihood and color neutrality is determined for the current pixel color value. An output pixel color value depending upon the color neutrality and the highlight likelihood is generated. The input pixel color value is obtained from an image acquisition system and the output color pixel value is used by an output engine to render the pixel.
