摘要： A method of removing ringing and blocking artifacts from a decompressed digital image. In one method, a background value of the digital image a background region and foreground regions is determined, and a threshold value is computed. A mapping of the digital image is then generated by thresholding the digital image based on the threshold value to produce a thresholded image, and enlarging the foreground regions of the thresholded image to form a map image. The mapping includes the background pixels of the map image. The background region of the decompressed digital image is then cleansed based on the mapping. In an alternate method, ringing artifacts are removed from a decompressed digital image based on a signal-to-noise ratio of the image. In yet another alternate embodiment, ringing artifacts are from a decompressed digital color image that includes a chrominance channel and a luminance channel. An alternate embodiment removes ringing and blocking artifacts.

摘要： The present invention relates to the segmentation of an image into a main area and a image segment for variable data differential gloss image control. A single color is selected. Two or more different color definitions are created by combining the selected single color with two or more halftones having anisotropic structure characteristics which are significantly different in orientation to each other while remaining identical in density. By alternatively assigning the color definitions to the image segment in accord with the variable data content, a variable data differential gloss image may be superimposed within an image having reduced data processing and storage requirements.

摘要： A method for editing image data includes segmenting input image data into a plurality of discrete objects, wherein each of the objects is defined by a plurality of input pixels that are spatially grouped and that relate to a common content type and feature of the input image data so as to define an objectized input image from the input image data. The objectized input image and a holding area image are generated and simultaneously displayed. Editing input is received from a user by user selection of an object of the objectized input image that the user desires to be moved from the objectized input image to the holding area image based upon the user's visual inspection of the objectized input image. The objectized input image and the holding area image are updated based upon the received editing input so that the selected object is deleted from an original location in the objectized input image and inserted into the holding area image as a temporary object at an insertion location that spatially corresponds to the original location of the objectized input image. The method further includes receiving replacement input data from the user that indicates a selected replacement object in a replacement object database to be inserted into the original location of the objectized input image. The objectized input image is updated to include the selected replacement object in the original location to define an objectized output image.

摘要： A method for run-time streak removal from a scanned image includes providing a scan line of image data from the scanned image; detecting corrupted data within the scan line; evaluating image data located in a neighborhood before and after the corrupted data on the scan line; if the evaluated image data in the neighborhood is smooth, replacing the corrupted data with image data determined by a linear interpolation process; and else if the evaluated image data in the neighborhood is not smooth, replacing the corrupted data with image data determined by the linear prediction process. Various techniques can be used to evaluate the image data located in the surrounding neighborhood. For example, a filter selection step may be used based on prediction discrepancies.

摘要： As set forth herein, a computer-implemented method facilitates replacing text on cylindrical or curved surfaces in images. For instance, the user is first asked to perform a multi-click selection of a polygon to bound the text. A triangulation scheme is carried out to identify the pixels. Segmentation and erasing algorithms are then applied. The ellipses are estimated accurately through constrained least squares fitting. A 3D framework for rendering the text, including the central projection pinhole camera model and specification of the cylindrical object, is generated. These parameters are jointly estimated from the fitted ellipses as well as the two vertical edges of the cylinder. The personalized text is wrapped around the cylinder and subsequently rendered.

摘要： Systems and methods are described that facilitate identifying objects in a document (e.g., a PDF document) for automatic image enhancement (AIE). A PDF document is “chunked” or segmented into chunks, and boundaries between chunks are identified as real or imaginary. Chunks sharing imaginary boundaries are combined, while real boundaries are retained, to generate “de-chunked” objects. These objects are then classified, and an AIE application is executed on objects meeting pre-specified classification criteria. In this manner, objects of r which AIE is not desired are not subjected to the AIE application, thereby saving time and processing resources associated with enhancing the document.
摘要翻译：描述了便于识别用于自动图像增强（AIE）的文档中的对象（例如，PDF文档）的系统和方法。 PDF文档被“分块”或分割成块，并且块之间的边界被识别为实部或虚构。组合共享虚拟边界的块，而保留实际边界，以生成“去分块”对象。然后对这些对象进行分类，并在符合预先指定的分类标准的对象上执行AIE应用程序。以这种方式，不需要AIE的对象不进行AIE应用，从而节省与增强文档相关联的时间和处理资源。
