摘要： A robust recursive operator for fast implementation of the computationally intensive module of Retinex-type image enhancement algorithms. The proposed module includes a cascaded recursive filter (44). The parameters of the filter are a function of the input signal, and are scale independent. Furthermore, the image is first processed according to an open and close prefilter (42), followed by application of the cascaded recursive filters (44). After application of the cascaded recursive filters, a post filter maximum output is applied to the signal (54). The module will usually be used as a part a Retinex-type image processing system, which might use it after some preprocessing of an input image, and which will result in a manipulation of the input image and the module's output image.

摘要： Method embodiments of the present invention provide for semi-automated or fully automated assessment of the quality of device-rendered text, including graphical symbols, characters, and other printable or displayable patterns. Method embodiments of the present invention employ one or more metrics that involve the comparison of input characters, including text characters, symbols, and character-like graphics, with corresponding digital output characters obtained by capturing images of characters rendered by a character-rendering device. The one or more metrics include individual computed relative entropy APQi metrics, reflective of differences in character-to-character distance distributions between one input character c, and the set of input characters c*, a cumulative computed relative entropy APQ, stroke irregularity, contrast measure, sharpness, and background uniformity. These individual metrics can be computed and stored separately as well as output to a user of a character-rendering-quality measurement system, or may be combined together in various ways to produce one or more comprehensive, cumulative metrics for storage and output.

摘要： Embodiments of the present invention are directed to determining the spectral vector of electromagnetic radiation reflected from, transmitted through, or emitted from a sample using a set of n intensity measurements. In general, the spectral vector has a dimension k that is greater than the number of measured intensities n. However, in many cases, the physical and chemical constraints of a system, when properly identified and modeled, effectively reduce the number of unknowns, generally the k components of the spectral vector, to an extent that allows for the spectral vector to be characterized from a relatively small number n of measured intensities.
摘要翻译：本发明的实施例涉及使用一组n个强度测量来确定从样品反射，透射或从样品发射的电磁辐射的光谱向量。通常，光谱矢量的尺寸k大于测量的强度n的数量。然而，在许多情况下，系统的物理和化学约束在适当地识别和建模时有效地将未知数（通常是频谱矢量的k分量）的数量有效地减少到允许频谱向量的特征相对较小的n个测量的强度。

In another aspect, a code (18) corresponding to an encoded image with pixel values quantized to respective quantization levels is received. The code (18) is decoded based at least in part on a mask lookup table (20) assigning index values to respective masks (32), wherein each mask (32) corresponds to a respective spatial distribution of the quantization levels.
