摘要： A method for processing a digital image in a distributed manner to produce a final modified digital image includes providing a source digital image at a first computer, providing the source digital image at a second computer, and modifying the source digital image at the second computer to form a first modified digital image. The method further includes determining a difference digital image representing the difference between the source digital image and the first modified digital image, transferring the difference digital image to the first computer, and combining the difference digital image with the source digital image at the first computer to form the final modified digital image.

摘要： A new multitoning technique is proposed that combines error diffusion, blue-noise dithering and over-modulation in an adaptive algorithm to achieve high quality multilevel printing with smooth texture transition. A periodic dither signal is first added to an input digital image wherein the amplitude of the periodic dither signal is a function of the input pixel value for each input pixel. The amplitude of the periodic dither signal is larger for input pixel values near the N output levels, and the amplitude of the periodic dither signal is smaller for input pixel values intermediate to the N output levels to produce a modified input image. Then, a multi-level error diffusion halftoning algorithm is applied to the modified input image wherein the error diffusion halftoning algorithm uses a set of error feedback weights which are adjusted according to the original input pixel value for each input pixel. The sum of the error feedback weights is smaller for input pixel values near the N output levels, and the sum of the error feedback weights is larger for input pixel values intermediate to the N output levels to produce an output multi-level digital image.
摘要翻译：提出了一种新的多线程技术，将自适应算法中的误差扩散，蓝噪声抖动和过调制相结合，实现了平滑纹理转换的高质量多层次打印。周期性抖动信号首先被添加到输入数字图像中，其中周期性抖动信号的幅度是每个输入像素的输入像素值的函数。周期性抖动信号的幅度对于接近N个输出电平的输入像素值较大，并且周期性抖动信号的幅度对于在N个输出电平之间的输入像素值较小，以产生经修改的输入图像。然后，将多级误差扩散半色调算法应用于经修改的输入图像，其中误差扩散半色调算法使用根据每个输入像素的原始输入像素值调整的一组误差反馈权重。误差反馈权重的和对于N个输出电平附近的输入像素值较小，并且对于N个输出电平之间的输入像素值，误差反馈权重之和较大，以产生输出多电平数字图像。

摘要： A method for transforming input color values to device control signals for a color printing device having an output response that is approximately invariant for ranges of the device control signals near the maximum or minimum allowable device control signals, wherein the input color values are transformed into the device control signals that are to be used to reproduce the input color values is disclosed. The method includes determining color reproduction characteristics for the color printing device over an allowable range of input signal values; determining a full color gamut for the color printing device describing a full range of color values that can be produced by the color printing device; creating a reduced color gamut by shrinking the full color gamut; and transforming the input color values to the device control signals using the determined color reproduction characteristics of the color printing device, wherein the input color values that are outside the reduced color gamut are mapped to color values that are on or within the reduced color gamut.

摘要： Multi-channel color image signals from a digital camera having multi-channel image sensors are corrected to account for variations in scene illuminant. This is accomplished by determining the scene illuminant and determining an optimum color-correction transformation in response to the scene illuminant which transform minimizes color errors between an original scene and a reproduced image by adjusting three or more parameters.
