摘要： Image processing transforms input multi-level image data into output image data having a smaller number of levels (the input and output image data represents images formed of cells). The image processing distributes quantization error of a target cell of the image to neighbour cells in proportions determined by a set of weights. The distribution excludes neighbour cells whose data level is less than a threshold value from receiving distributed quantization error, or allows just a fraction of the quantization error to be distributed to such neighbour cells.
摘要翻译：图像处理将输入的多级图像数据变换为具有较小级数的输出图像数据（输入和输出图像数据表示由单元形成的图像）。图像处理以由一组权重确定的比例将图像的目标小区的量化误差分配给相邻小区。该分布从接收分布式量化误差中排除其数据级别小于阈值的相邻小区，或者允许将仅一部分量化误差分配给这样的相邻小区。

摘要： A printer and a method of processing an image (1) to be printed with a printer which has a printing unit arranged to produce a printout from image-representing print data of the image, and a processing unit for processing image-representing input data of the image so as to generate the image-representing print data. The processing unit is arranged for separating the image into a line detail sub-image (20) containing edge and line details, and an area detail sub-image (25) containing area details, performing a first printing mode processing pipeline on the line detail sub-image and performing a second, different printing mode processing pipeline on the area detail sub- image, and generating multi-layer print mask data, wherein at least one print mask data layer is usable to print the line detail sub-image in at least one line detail print pass, and the remaining, i.e. at least one, of the print mask data layers being used to print the area detail sub-image in at least one area detail print pass to produce an image (50) which has optimized image quality.

摘要： An example device includes a camera to aim towards a build platform to receive material to be fused to form an article. The camera is to capture thermal images including a correction image captured during formation of the article at the build platform. The correction image is to be referenced to adjust a parameter of the formation of the article at the build platform. The example device further includes a controller connected to the camera. The controller is to control the camera to capture a calibration image with a heater associated with the build platform turned on. The controller is further to use the calibration image to compute a calibration to apply to the correction image.
