摘要： In a mixed raster content (MRC) image data format, where a separation plane is used to define portions of the image to compressed in a lossy or lossless manner, edge pixels are identified in the separation plane. Each edge pixel is modified to assume a maximum luminance and most neutral chrominance found among neighboring pixels. The modification of the edge pixel data minimizes artifacts such as fringe effects when the image data is compressed and subsequently decompressed.

摘要： A method and apparatus for digital image processing are provided for controlling chrominance channel overshoot in response to FIR or other enhancement processing. The chrominance values defining the enhanced digital image data for each pixel are compared to corresponding local minimum and maximum chrominance values of the non-enhanced image obtained from the neighborhood of the subject pixel. If an enhanced chrominance value for a subject pixel falls outside the corresponding local minimum/local maximum chrominance range by an overshoot amount, the enhanced chrominance value is adjusted to reduce the overshoot amount. The overshoot amount is adjusted according to a pre-programmed overshoot reduction parameter.

摘要： A method and apparatus for digital image reduction using an improved “extendible” perspective projection technique which allows for flexible control of the averaging cell or window size separately from the reduction ratio to improve moir{acute over (e)} suppression or sharpness as desired in the resulting reduced-size image. The extendible perspective projection technique can also be implemented together with ordinary perspective projection or together with a combined one-dimensional filter and linear interpolation technique to produce a reduced-size image of a quality comparable to those produced by the prior technique of using a two-dimensional pre-filter prior to interpolation at a much lesser cost due to the reduced number of required scanline buffers.

摘要： A portable computer-vision-based non-contact vibration detection system and method. The system can process small vibrations and large vibrations separately in the captured images. The small vibrations can be enhanced, and the enhanced small vibrations are analyzed, and the analysis results of the small vibrations and large vibrations are fused, and the processed images are displayed through a GUI. The analysis results include displacements in Region of Interest, vibration frequencies or cycles, vibration amplitudes and phase angles, root mean square (RMS) values, etc., along with overall ‘virtual’ snapshots of vibrations with maximum amplitudes during the working period of the camera.

摘要： A system and method convert a pixel of binary image data to a pixel of contone image data by determining if a predetermined pixel of binary image data is part of a solid edge or part of a fuzzy edge. A binary to contone conversion circuit converts the predetermined pixel of binary image data to a pixel of a first contone image data value, and a filter circuit converts the predetermined pixel of binary image data to a pixel of a second contone image data value. The filter circuit uses an adaptive filtering operation wherein the adaptive filtering operation utilizes one of a plurality of sets of weighting coefficients to change a characteristic of the filtering operation. The set of weighting coefficients used in the filtering operation are selected in response to a fuzzy edge detection. A selection between the first contone image data value and the second contone image data value is made based upon the determination as whether the predetermined pixel of binary image data is part of a solid edge.

摘要： Embodiments relate to systems and methods for a computation-efficient image processing system architecture. Image data can be transmitted from a computer, online service, and/or other image source to an output device having a set of image processing modules in two or more image paths, including an edge detection module and a video decoding module. The edge detection module can produce edge tag output, and the video decoding module, operating in parallel, can generate decoded video output. The edge tag output and decoded video output can be transmitted to a set of downstream image processing modules, including modules for color trapping, edge smoothing, and other operations. Because earlier processing stages share information with downstream modules which require the same or related data, redundant processing can be reduced or eliminated. Complex image operations can therefore be carried out, and high-quality output can be generated, without sacrificing responsiveness.
摘要翻译：实施例涉及用于计算高效图像处理系统架构的系统和方法。图像数据可以从计算机，在线服务和/或其他图像源发送到包括边缘检测模块和视频解码模块的两个或多个图像路径中的具有一组图像处理模块的输出装置。边缘检测模块可以产生边缘标签输出，并行的视频解码模块可以产生解码的视频输出。边缘标签输出和解码视频输出可以传输到一组下游图像处理模块，包括用于色彩捕捉，边缘平滑和其他操作的模块。因为较早的处理阶段与需要相同或相关数据的下游模块共享信息，所以可以减少或消除冗余处理。因此，可以执行复杂的图像操作，并且可以产生高质量的输出，而不牺牲响应性。

摘要： Disclosed is a processor-implemented method for processing image data representing a document using an image processing apparatus. The processor receives image data, determines the classifications and counts of pixels in the image data (e.g., in device independent space that are degrees of neutral or non-neutral), classifies the image data into a category based on the determination of classifications and counts of pixels, and determines a billing structure for the image data based on the classification of image data. The classification can be performed on the image data prior to conversion into device dependent space. For example, by counting true color, neutral, non-neutral, and fuzzy color pixels and comparing them to thresholds, the image data can be classified as neutral or very colorful. By classifying images earlier in the image path, errors in billing are reduced.
摘要翻译：公开了一种处理器实现的方法，用于使用图像处理装置处理表示文档的图像数据。处理器接收图像数据，确定图像数据中像素的分类和计数（例如，在与中性或非中性度无关的设备无关的空间中），根据分类和计数的确定将图像数据分类为类别的像素，并且基于图像数据的分类来确定图像数据的计费结构。可以在将图像数据转换成依赖于设备的空间之前执行分类。例如，通过计数真实颜色，中性，非中性和模糊颜色像素并将其与阈值进行比较，图像数据可以分为中性或非常丰富多彩。通过在图像路径中较早的分类图像，计费中的错误会减少。
