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： An image finder method and apparatus are provided for identifying a source image data file in a database based upon a printed image actually generated from a source image data file in the database. Input image data that represent a printed input image are received from a scanner. Source image data are received from the database that is defined by a plurality of different source image data files stored on a CD-ROM or other storage medium. Correlation operations are carried out to identify any source image data files that are highly correlated with the input image data. The results of the correlation operations are used to identify the source image data file from which the input printed image was actually generated or, if this is not possible, to identify more than one source image data file that could be the source image data file from which the printed input image was actually generated. Both the input image data and source image data are severely subsampled to obtain no more than about 1000 (and most preferably no more than 200) data values from each set of data for use in the correlation operation to provide for extremely fast processing without loss of accuracy.

摘要： An image watermarking method includes a color transform on RGB image data to derive CMYK image data that define a constant K image. Variable infrared (IR) mark data defining an IR mark are received and a sparse two-dimensional pattern of black pixels is defined that corresponds to the variable IR data, e.g., using Gold codes or pseudorandom binary sequences. A watermarked black separation K″ is defined by embedding the sparse two-dimensional pattern into the constant K black separation K′ while maintaining local average levels. A watermarked image includes the watermarked black separation K″ in combination with the CMY separations of the constant K image. A decoding process includes using an IR microscope fitted with IR LEDs and an IR pass filter to capture an IR image, which is subjected to exposure correction, thresholding, and dilation operations to extract the two-dimensional pattern for subsequent correlation processing.

摘要： A show-through reduction method is disclosed. The method is designed to deal with both light and severe show-through. The method focuses mostly on text documents, with characters possibly appearing in multiple gray levels, although the method can also be extended to color documents. As in the prior art, the front and back pages are processed in pairs. However, no perfect page alignment is assumed here, since we are dealing with real images. Instead, a front and back registration is performed as the first step before the pages are further analyzed. In this method, we are aligning the front page content with its show-through appearing in the back side, and the back page content with its show-through appearing in the front side. Once the two sides are aligned, masks are generated for both sides to differentiate severe show-through and light color content regions. Finally, different TRCs are applied to different regions. The show-through is reduced and the page contents are retained.
摘要翻译：公开了一种透视简化方法。该方法旨在处理轻型和重型展示。该方法主要集中在文本文档上，字符可能出现在多个灰度级，尽管该方法也可以扩展到彩色文档。如现有技术那样，前页和后页成对处理。然而，在这里假设没有完美的页面对齐，因为我们正在处理真实的图像。相反，在进一步分析页面之前，执行正面和背面注册作为第一步。在这种方法中，我们正在将首页内容与其后面的显示对齐，后端页面的内容与其显示出现在前面。一旦双方对齐，双方将产生掩模，以区分严重的透明和浅色内容区域。最后，不同的TRC应用于不同的地区。展示次数减少，页面内容保留。

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.
