摘要： Described herein is a method of scanning an image formed on a color filter array film using a monochrome scanner. The image forming layer of the film is chosen so as to have a maximum density which occupies a small portion of the dynamic density range of the scanner, the excess density range of the scanner being used to decode the colors of the color filter array.

摘要： The present invention relates to a system and method of word syllabification. The present invention receives a word to be syllabified and determines therefrom all possible substrings capable of forming part of the word. Sequences matching at least part of or the whole of the word are determined from the substrings together with respective probabilities of occurrence and the sequence having the greatest probability of occurrence is selected as being the most probable syllabification of the word. The most probable sequence can be determined in many different ways. For example, the sequence can be determined by commencing with the substring having the greatest probability of forming the beginning of a given word and subsequently traversing in a step-by-step manner a table comprising all possible substrings of the word and at each step selecting the next substring of the sequence according to which of the possible next substrings has the highest probability of occurrence. A further method of determining the most probable sequence would be to adopt the above step-by-step approach for all possible substrings capable of forming the beginning of the given word. Alternatively, all possible sequences of substring capable of constituting the word can be determined together respective probabilities of occurrence thereof and the sequence having the highest respective probability of occurrence is selected as being the most probable syllabification of the given word.

摘要： A shift and add digital image processor (1) includes two sections (3) and (5), each including a latch (10, 22) for latching an input signal, an adder (18, 28) for summing two channels output from the latch with programmable delay (14, 26) therebetween, and a bit-shifting scaler (20, 30) for generating "powers of two" functions from the output of the adder. By selecting the input to the second section (5) either from the output of the first latch (10) or from image pixels delayed by at least one line with respect to the pixels input to the first section (3), the processor may be set up to perform either one- or two-dimensional filter functions.

摘要： In a sampled data system with limited bandwidth where the output of a table memory 34 is multiplied with the sampled data in a multiplier 36 to produce a non-linear function, the process ordinarily produces harmonics that fold back into the passband of the system, thus causing artifacts in the processed data. By filtering the sampled data in a low pass filter 30 before addressing the table memory 34, the non-linearity of the function is progressively reduced toward the upper band limit. This reduces the production of harmonics and the resultant artifacts.
摘要翻译：在具有有限带宽的采样数据系统中，表存储器34的输出与乘法器36中的采样数据相乘以产生非线性函数，该处理通常产生折回到系统的通带中的谐波，因此在处理的数据中造成伪像。通过在寻址表存储器34之前对低通滤波器30中的采样数据进行滤波，功能的非线性逐渐地朝向上限频带减小。这减少了谐波的产生和所产生的伪像。

摘要： A bandpass enhancement filter has a pass-band that tracks changes in spatial frequency due to the use of a zooming process upon a digital image signal. The primary pass-band of the enhancement filter is derived from a combination of a plurality of secondary bandpass filter sections, each having a different frequency response and each responsive to a gain adjustment. A control signal reflecting a particular zoom ratio is used in the adjustment of the gain applied to the filter sections, thereby proportioning the output of each filter section so that the combined output tracks the zooming process.

摘要： An optical beam splitter is provided which removes aberrations such as coma and transverse chromatic aberration by subjecting all transmitted rays to equal and opposite amounts of induction of coma and transverse chromatic aberration, by curing residual astigmatism by providing a terminal astigmatism correcting lens in each transmitted ray path, and by avoiding ghost images by ensuring adequate separation between the main image and any ghost images. The splitter thus permits the use of high resolution, low sensitivity, linear charge coupled devices in image analysis.
