摘要： A method and apparatus for translating color to grayscale images, wherein at least some pixels of the color image having the same color are mapped to different grays in the grayscale image depending on the spatial surround of each pixel. Further, the method and apparatus may include applying a high pass filter to at least one chrominance component of a color image to generate at least one high pass filtered chrominance component, and adjusting a luminance component of the color image based upon the at least one high pass filtered chrominance component.

摘要： What is disclosed is a method for presenting spreadsheets and other documents on client-side devices with limited resources and tiny display screen area. The present invention involves the user, on a client-side device, scrolling through a condensed image view of a document with the user's viewpoint of the image repeatedly computed server-side. A split-bar is stitched into a composite view of the user's current viewpoint. The user clicks a scroll-bar or scroll-points to indicate an intended change in direction of their current viewpoint. The client-side device provides the server with information as to where and how the next viewpoint is to be updated. Responsive to the received client information the server updates the viewpoint currently displayed with the transmission of images therefor and provides the same back to the client. In such a manner, the computing power and resources of the server are utilized for the image manipulation, cropping, etc. rather than that of the client's handheld device.

The invention generally segments differing binary textures or structures within an input image by passing one or more structures while removing other structures. More particularly, the method and apparatus segment a stored binary image using a template matching filter that is designed to pass therethrough, for example, text regions while removing halftone regions.

摘要： An improved technique for processing a color or gray scale pixel map representing a document is disclosed. The pixel map is decomposed into a three-plane representation, a reduced-resolution “upper” plane, a reduced-resolution “lower” plane, and a high-resolution binary selector plane. The “upper” and “lower” planes contain the color or gray scale for the page as well as the continuous tone pictures that are contained on the page. The selector plane stores information for selecting from either the foreground plane or background plane during decompression. Information contained in the selector plane is first used to pre-process the upper and lower planes to reduce the amount of data on each of the other two planes that will be subjected to further processing. Each of the pre-processed planes is compressed using a compression technique optimal for the type of data that resides upon it.

摘要： A method and apparatus for insertion of a secondary digital image, such as a digital image of a photograph or the like, into a base digital image without requiring the base document image data to be decompressed for purposes of locating the appropriate paste location or to perform the actual electronic pasting operation. The JPEG or otherwise compressed base digital image is segmented into information areas and background areas without decompressing the base digital image so that each background area is identified as a potential paste location for the compressed secondary digital image. The segmentation operation is performed on the basis of the encoding “cost” of each block and the DC coefficient of the block. Without decompressing the base digital image, a select background area is identified therein which is sufficiently large to receive the compressed secondary digital image. The compressed secondary image is pasted into the identified select background area of the compressed base digital image without decompressing either the base or the secondary images.

摘要： A method for processing an input image including a plurality of input pixels each having a first number of possible input levels of optical density to form an output image including a plurality of separations each including a plurality of output pixels each having a second number of possible output levels of optical density. The method includes the steps of generating a first threshold reference signal as a function of the output levels of optical density of a plurality of corresponding pixels each being selected from one of the plurality of separations, modifying a current one of the plurality of input pixels in a current one of the plurality of separations in accordance with an error signal derived by processing previous ones of pixels in the current one of the plurality of separations, generating a second threshold reference signal according to the output levels of optical density of previously processed pixels in the current one of the plurality of separations, and forming one of the output pixels by comparing the modified current one of the plurality of input pixels to the generated first threshold reference signal and the generated second threshold reference signal.

摘要： A method of decompressing a document image compressed with JPEG ADCT or the like method of compression includes: a) receiving encoded quantized transform coefficient blocks for the original image; b) removing any lossless encoding of the quantized transform coefficient blocks for the original image; c) multiplying each quantized transform coefficient in a block by a corresponding quantizing value from the quantization table to obtain a block of received transform coefficients; d) recovering the image by applying an inverse transform operation to the received transform coefficients; e) reducing high frequency noise appearing in the recovered image as a result of the lossy quantization process, while preserving edges, whereby the appearance of the recovered image is rendered more visually appealing; f) changing the filtered recovered image into blocks of new transform coefficients by the forward transform coding operation using the frequency space transform compression operation; g) comparing each block of new transform coefficients to a corresponding block of received transform coefficients and the selected quantization table, to determine whether the filtered recovered image is derivable from the original image; and h) upon the determination transferring the filtered recovered image to an output buffer.

摘要： A document may include a non-magnetic substrate, a first colorant mixture printed as a first image upon the substrate, the first colorant mixture including a magnetic ink, and a second colorant mixture printed as a second image upon the substrate in substantially close spatial proximity to the printed first colorant mixture. The second colorant mixture may consist essentially of one or more non-magnetic inks and exhibit properties of both low visual contrast and high magnetic contrast against the first colorant mixture, such that the resultant printed substrate does not reveal the first image to the human eye, but will reveal the first image to a magnetic image reader.
