摘要： Apparatus and method for flexible digital halftoning are provided in which novel pattern choices are allowed by not restricting the basic halftone patterns to grow sequentially. Rather, positions in a threshold array allow multiple transitions between on (i.e., printed with toner/ink) and off (not printed) as a function of the input value at the corresponding position. In one embodiment, multiple threshold matrices are employed and the output decision is a vote (e.g., exclusive OR) of the outputs of the individual threshold matrices. In another embodiment, each position contains an arbitrary bit vector to express the output for each input. This flexibility in growing basic halftone patterns allows the number of densities output to be larger than n+1 (where “n” is the number of dots within a basic halftone cell).

摘要： Fast transforms that use early aborts and precision refinements are disclosed. When to perform a corrective action is detected based upon testing the incremental calculations of transform coefficients. Corrective action is then performed. The corrective action includes refining the incremental calculations to obtain additional precision and/or aborting the incremental calculations when the resulting numbers are sufficient.

摘要： Disclosed is a method, system, and program for halftoning data for an output device capable of rendering multiple intensities. Input values are received. For each received input value, the input value is used as an output value if the input value is a predetermined value. Otherwise, if the input value is not the predetermined value, then the input value is halftoned to produce an output value used to render one of multiple intensities. This allows the use of data intended for bi-level printers that may have already been halftoned.

摘要： A system and method for generating bounded-loss color transformations employed in the compression and decompression of multi-spectral images is provided. The bounded-loss color space transformations provide transformations from a first color space to a second color space and back to the first color space with bounded loss or error. The bounded loss or error allows for the near lossless compression and reconstruction of multi-spectral images transformed from a first color space to a second color space and ultimately back to the first color space.

摘要： This invention solves problems due to employing error degraded data in digital processing. It particularly solves multi-generation problems wherein transform data degrade during each inverse transform and forward transform cycle even without any processing due to the rounding and clipping errors. It provides methods, systems and devices for reduced-error processing of transform-coded data. After inverse transformation of transform data, high-precision numbers are converted to integers and clipped to an allowed range forming converted data. High-precision differences are obtained by subtracting the high-precision output of the inverse transform from the converted data. The converted data can be manipulated and sent to output devices which expect integer data. Processed high-precision numbers are formed by adding the high-precision differences to the processed converted data. Thus, the rounding and clipping errors are greatly reduced in the processed high-precision numbers. The processed high-precision numbers are used for further processing including forward transforming back to the transform domain. In another embodiment of the present invention processed high-precision numbers are generated by selecting the high-precision numbers instead of the manipulated converted data whenever the manipulated converted data still equals the converted data. Although advantageous to many applications employing digital transformed data, the invention is particularly advantageous for use in digital studios during editing of MPEG-coded, JPEG-coded and wavelet-coded video and audio data.

摘要： This invention solves problems due to employing error degraded data in digital processing. It particularly solves the multi-generation problem wherein transform data degrade during each inverse transform and forward transform cycle even without any processing due to the rounding and clipping errors. It provides methods, systems and apparatus for transform-domain correction of real-domain errors in the processing of transform, transform-coded, and coded data. After inverse transformation of transform data the high-precision numbers are converted to integers and clipped to an allowed range forming converted data. High-precision differences are obtained by subtracting converted data from the high-precision output of the inverse transform. The differences are re-transformed back to the transform domain and saved. In an alternate embodiment the differences are quantized, thus, only significant errors are saved. In still another embodiment the quantized differences are entropy encoded. Then after re-transforming the processed converted data, the decoded differences, the dequantized differences, or the transformed differences can be used in the transform domain to remove the real-domain errors introduced by the original conversion to integers and clipping to the allowed range.
摘要翻译： 本发明解决了由于在数字处理中采用错误退化数据而引起的问题。 它特别解决了在每次逆变换和正向变换循环期间，由于舍入和削波错误，即使没有任何处理，变换数据也会降级的多代问题。 它提供了在转换，变换编码和编码数据处理中对实时域错误进行变换域校正的方法，系统和装置。 在对变换数据进行逆变换之后，高精度数字被转换为整数，并被裁剪成允许的范围形成转换数据。 通过从逆变换的高精度输出中减去转换后的数据可以获得高精度的差异。 差异被重新转换回变换域并保存。 在替代实施例中，差异被量化，因此仅节省重大误差。 在另一个实施例中，量化的差异是熵编码的。 然后，在对转换后的数据进行重新变换之后，可以在变换域中使用解码的差异，反量化差异或变换后的差异，将原始转换引入的实际误差除以整数，并将其削减到允许范围。

摘要： A method for management of federated information in associated knowledge systems. The method includes maintaining a data structure, the data structure including associative metadata that correlates a plurality of substantive knowledge entities from a plurality of disparate knowledge bases; monitoring the substantive knowledge entities for an access-limiting event; determining the access-limiting event on at least one of the substantive knowledge entities; and responsive to determining the access-limiting event, adding to the associative metadata a persistent audit enhancement indicative of the access-limiting event, the persistent audit enhancement including a timestamp. The access-limiting event may include deletion of a substantive knowledge entity, enacting more restrictive access permissions for a substantive knowledge entity, and copying of a substantive knowledge entity to a more restrictive access area.

摘要： The scaling down of data is provided. At least two blocks of transformed data samples representing at least two blocks of original data samples are received. One of at least two tables of constants is selected wherein each table of constants is capable of reducing the number of transformed data samples by a different factor. The constants taken from the selected table are applied to the at least two blocks of transformed data samples to produce one block of transformed data samples representing one block of final data samples. The data is processed one dimension at a time by multiplying the data in one dimension with selected constants taken from previously developed tables corresponding to the desired scale down factor. Scaling down by different factors in each dimension as well as scaling down in one dimension and scaling up in the other dimension may be achieved. In addition, the de-quantization of the quantized transform coefficients may be accomplished by pre-multiplication of the selected constants when the quantization values are known. In a similar way the re-quantization may be accomplished by a pre-division of the selected constants. Both de-quantization and re-quantization may be combined when the input quantized transform coefficients and output quantized transform coefficients are desired.

摘要： A mechanism for automatically managing process information stored in federated repositories. When practice requirements are collected for a multi-step process, a process metadata data structure comprising process information conforming to the practice requirements is created in a metadata repository. The structure is created by creating a template document for each task in the multi-step process and populating the template documents with the procedure information in the practice requirements. Hierarchical and horizontal associations are created among the template documents based on the execution order of the tasks in the procedure information. Process documents for each task in the multi-step process are created and populated with information about the tasks. The task information, procedure information, and association information for each task is then stored as metadata in the process metadata structure.
