摘要： Image data is analyzed line by line to identify pixels having similar color and edge characteristics. The pixels on one line are linked to pixels on another line, if they share similar characteristics. The linked pixels are then grouped together in regions and the average color of the region is calculated. An image map is generated that identifies the regions to which the pixels belong, along with a final table of the regions appearing in the image.

摘要： The image data is processed into a background plane and a plurality of foreground planes. Holes are inserted onto the background plane, in regions which are assigned to a foreground plane. The background plane is sub-sampled, and holes remaining in the sub-sampled image are filled with the average color of the non-zero sub-sampled pixels over pre-determined blocks such as JPEG blocks. If a block is entirely made of holes, the block is filled with a constant color that is propagated from the average color of a previous block. The resulting background plane is far smoother than the original image data and thus can be effectively sub-sampled and highly compressed without adverse deterioration in reconstructed image quality.
摘要翻译：图像数据被处理成背景平面和多个前景平面。在分配给前景平面的区域中，将孔插入到背景平面上。对背景平面进行二次采样，并且通过诸如JPEG块之类的预定块的非零子采样像素的平均颜色填充剩余在子采样图像中的孔。如果一个块完全由孔组成，则该块被填充有一个恒定的颜色，该颜色从先前块的平均颜色传播。所得到的背景平面比原始图像数据更平滑，因此可以有效地进行子采样和高度压缩，而不会造成重建图像质量的恶化。

摘要： The image data is analyzed to identify blobs having similar characteristics. Various blobs are gathered together and placed into a foreground plane based on one or more color characteristics and/or spatial characteristics. Each blob gathered onto a foreground plane has a color that is similar to a color associated with that foreground plane. One or more portions of the image data that is not mapped into any foreground plane may be mapped into a background plane.

摘要： The image data is initially processed in a manner that is similar to that used to convert the image data into 3-layer mixed raster content format. After the image data is initially processed through a first stage of the three-layer segmentation process, rather than completing the segmentation into foreground and background planes, the image data is analyzed to identify regions having similar image characteristics. These regions are grouped together in cluster if they share color characteristics and are spatially close. The clusters are then sorted according to their size, and placed into a binary foreground plane based on one or more color characteristics. Each cluster gathered into a binary foreground plane having the same color as the color of the cluster.

摘要： A highly efficient method and system for eliminating halftone screens from scanned documents while preserving the quality and sharpness of text and line-art is disclosed. The method and system utilizes a single channel screen frequency estimator module, which generates a screen frequency estimate for image data. The module generates a signal based on the highly filtered image signal at low contrast levels, and based on a reliable estimate to the halftone frequency at higher contrast levels. The single channel screen estimate module has adequate performance in resolution ranges from 300 to 600 dpi.

摘要： Apparatus and methods for de-screening an image signal utilizing a bank of filters to provide several increasingly blurred versions of the original image signal is disclosed. At any given time, one or more of the blurred versions are created, on a pixel-by-pixel basis. The outputs from a selected pair of blurred signals are then blended together to create a variable blending output that can vary smoothly from no blurring to maximum blurring in a smooth and continuous manner. In addition, the apparatus and methods provide enhanced text and line art by using a variable un-sharp masking mechanism with independent post-blur sharpening control, and detect and enhance neutral (no-color) output pixels.

摘要： Reduced size images may be generated by separating dimensions that span the original image into a plurality of groups so that data in each group of one or more dimensions may be processed differently from data of other groups. For example, for two-dimensional images, pixels of selected lines may be completely discarded or skipped while pixels of remaining lines may be processed along the x-dimension to obtain data of the reduced size image. The main advantages include very fast and efficient implementation, minimal storage requirements, and good image quality.
摘要翻译：可以通过将跨越原始图像的维度分离成多个组来生成缩小尺寸的图像，使得可以以与其他组的数据不同的方式处理一个或多个维度的每个组中的数据。例如，对于二维图像，可以完全丢弃或跳过所选行的像素，同时可以沿x维度处理剩余行的像素以获得缩小尺寸图像的数据。主要优点包括非常快速高效的实现，最小的存储要求和良好的图像质量。

摘要： Image representation is performed by dividing a source image into foreground, background and selector planes. The foreground plane is selected to contain mainly line type art or textual type information, the background plane mainly contains image data, and the selector plane identifies whether the image data is maintained in either a specific plane or a combination of planes. A color is selected, by averaging or selecting an appropriate value based on overflow or other criteria, to replace each color in the foreground plane. Error in portions of the foreground plane resulting from replacing foreground colors is fed into corresponding portions of the background plane. Each plane is then compressed using compression schemes appropriate for the type of data maintained in each plane (LZW for the foreground, and JPEG for the background and lossless fax LLITT, for example). Image reconstruction is performed by decompressing each of the foreground and background planes, and selecting pixels from each of the foreground plane and an additive image produced by combining image data from both the foreground, background, and selector planes. The selection is made based on the selector plane (selection mask), which identifies where image data is maintained for the reconstructed image (i.e., the upper plane or a combination of planes).
摘要翻译：通过将源图像划分为前景，背景和选择器平面来执行图像表示。前景平面被选择为主要包括线型艺术或文字类型信息，背景平面主要包含图像数据，并且选择器平面识别图像数据是保持在特定平面还是平面的组合中。通过平均或基于溢出或其他标准选择适当的值来选择颜色来替换前景平面中的每种颜色。将由前景颜色替换得到的前景平面的部分中的错误馈送到背景平面的相应部分。然后使用适合于维持在每个平面中的数据类型（例如，前景为LZW，背景为JPEG和无损传真LLITT）的压缩方案来压缩每个平面。通过解压缩前景和背景平面中的每一个以及从前景平面中的每一个选择像素和通过组合来自前景，背景和选择面的图像数据产生的附加图像来执行图像重建。基于选择器平面（选择掩模）进行选择，该选择器平面识别重建图像（即，上平面或平面组合）保持图像数据的位置。
