摘要： A system includes a computing device that includes a memory configured to store instructions. The computing device also includes a processor to execute the instructions to perform operations that include receiving a request from an imaging device indicating that the imaging device is unable to present textual content of an asset. The request includes one or more attributes of the textual content of the asset and the request is sent from the imaging device absent user input. Operations also include identifying an appropriate amount of font information from the received one or more attributes for the imaging device to present the asset, and, providing the identified font information to the imaging device for presenting the asset.

摘要： A computing device includes a memory for storing instructions and a processor. The processor is configured to execute the instructions to identify a location for a graphical element in a predefined three-dimensional scene using depth information of content included in two or more different two-dimensional representations of the predefined three-dimensional scene. The processor is also configured to produce two or more different two-dimensional representations of the predefined three-dimensional scene including the graphical element.

摘要： The automatic generation and use of halftone supercell threshold arrays suitable for high addressability output devices, particularly ones with constraints on sub-pixel combinations or geometries is disclosed. An example of a high addressability device is a laser printer using a pulse width modulator. The invention can further extend the usefulness of supercell halftone screening systems.

摘要： A method of adaptive spatial filtering for enhancing digital images is presented. A window is applied to a source pixel to generate an array of windowed pixels. An upper threshold value and lower threshold value corresponding to the maximum and minimum pixel values, respectively, in the array of windowed pixels are determined. A spatial frequency filter is applied to the array of windowed pixels to generate a filtered array of pixels including a reference pixel. The values of the source pixel and the reference pixel are scaled by respective weighting factors and then combined to create an enhanced pixel value. If the enhanced pixel value exceeds the upper threshold value, the enhanced pixel value is replaced by the upper threshold value. Similarly, if the enhanced pixel value is less than the lower threshold value, the enhanced pixel value is replaced by the lower threshold value. The resulting array of enhanced values provides greater edge transitions yet does not result in overshoot and undershoot regions which are generated by many traditional edge enhancement methods. In addition, color shifts associated with independent processing of individual color planes are avoided.
摘要翻译：提出了一种用于增强数字图像的自适应空间滤波方法。将窗口应用于源像素以生成窗口像素阵列。确定对应于窗口化像素阵列中的最大和最小像素值的上阈值和下阈值。将空间频率滤波器应用于窗口化像素阵列以产生包括参考像素的滤波像素阵列。源像素和参考像素的值由相应的加权因子缩放，然后组合以产生增强的像素值。如果增强像素值超过上限阈值，则增强像素值被上限阈值代替。类似地，如果增强像素值小于下阈值，则增强像素值被下阈值代替。所得到的增强值阵列提供更大的边缘转换，但不会导致由许多传统边缘增强方法产生的过冲和下冲区域。另外，避免了与单独色彩平面独立处理相关联的色彩偏移。
