    摘要： One aspect of the method/apparatus finds, for each input-image pixel, an “offset weighted average” of neighboring-pixel interactions—and uses the averages to make a final image. Another aspect assumes a value for each pixel, to use in a final rendered image form—and, at each in a series of approximations, determines whether to change the value, and finds a probabilistic weight to help determine. Yet another finds, for each pixel, a numerical representation of neighboring-pixel interactions—and establishes a distance cutoff for use in defining “neighbor”, and uses the representation to decide whether to change color values. Still another finds a desired or ideal number of print passes, and adapts the number of passes actually used to the found number. Another combines halftoning and printmasking into one procedure and prints images prepared thereby. Another integrates halftoning and image filtering, to obtain esthetic visual effects, into one procedure—and prints images thus prepared.

    摘要翻译： 方法/装置的一个方面针对每个输入图像像素找到相邻像素相互作用的“偏移加权平均”，并且使用平均值进行最终图像。 另一方面假设每个像素的值用于最终呈现的图像形式，并且在每一个近似值中，确定是否改变该值，并找到一个概率权重以帮助确定。 另一个发现，对于每个像素，邻近像素相互作用的数值表示，并且建立用于定义“邻居”的距离截止，并且使用该表示来决定是否改变颜色值。 还有另一个发现期望或理想数量的打印通行证，并且将实际使用的通行数量调整到找到的号码。 另一个将半色调和打印掩码组合成一个过程，并打印由此制作的图像。 另一个将半色调和图像过滤整合到一个程序中获得美学视觉效果，并打印如此准备的图像。

    摘要： In one example, a control process for additive manufacturing includes: forming an extent of unfused build material on a support; applying a coolant to unfused build material within the extent of unfused build material in a pattern of spots; capturing a thermal image of the extent of unfused build material with a thermal imaging device; mapping a pixel location in the thermal image to a physical location for each of multiple spots in the pattern; and based on the mapping, establishing a transform between pixels on the thermal imaging device and physical locations on the support.
