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： 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 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 method and a system for separating an image signal into a set of image planes. The system comprises a min-max module, a dynamic threshold module and a separation module. The min-max module receives the image signal, searches for a minimum and maximum within at least one window centered on a current pixel in the image signal. The dynamic threshold module computes, for the window, based on the respective minimum and maximum received from the min-max module and the current pixel, a respective indicator representing the distance and direction of the current pixel relative to a respective threshold plane, and outputs a control signal based on the indicator. The separation module separates the image signal into the set of image planes in accordance with the control signal by including a representation of the current pixel in at least one of the image planes.

摘要： Methods and systems for adaptively thresholding color image pixels are based on determining a signed (e.g., a plus or minus sign) single-component gray image which can be supersampled and binarized. The method computes the distance of a given color image pixel from an idealized plane which segments the color space into two regions. The process is made adaptive by making the threshold a function of neighborhood pixels. This combines the information from all color channels, such as, for example, 3 or 4 color channels, into a high quality gray channel used for binarization.

摘要： A hyperacuity printing system for rendering bitmapped image data on a photosensitive recording medium, the bitmapped image data being rendered as an array of pixels across the photosensitive recording medium in a fastscan direction, and an orthogonal slowscan direction. This system includes a data source for supplying grayscale input image data and a scanning device for rendering grayscale output image data onto the recording medium. The scanning device has a device for writing scan spots on the recording medium. Further included in this system is transformation circuitry for transforming the grayscale input image data into grayscale output image data. The transformation circuitry includes a halftoner, a thresholder, and a selection device, where the selection device selects either the thresholder or the halftoner to provide the grayscale output image data. Finally, included is a modulating device coupled between the transformation circuitry and the scanning device for intensity modulating each of the scan spots in accordance with the grayscale output image data.

摘要： An engine renders digitally represented images in a reduced marking material mode and in other modes. A digitally represented unsharp mask of an image is produced and combined with the image. When in the reduced marking material mode, the unsharp mask is given a relatively high weight, such as 2.0 or higher. When in another mode, such as a normal printing mode, the unsharp mask is given substantially less weight, such as about 1.0.
