摘要： An automatic abstract character coding system automatically generates abstract coded characters (Figs. 5,6) from the text image of a document (100;Fig. 2) when the gross script-type is known to be, or is determined to be, a European type script. A connected component generating means (28) generates connected components from the pixels comprising the text image. A spatial feature determining means (30) generates a character cell (Fig. 4) surrounding one or more aligned connected component. A character-type classifying means (32) converts the character cell to one of a plurality of abstract character codes (Fig. 5).

摘要： The invention has means for judging the characteristics of a character from a feature amount of one inputted character, thereby allowing a suitable character recognizer to be adapted to the input character in accordance with the feature amount of the input character. According to the invention, since the means for judging the characteristics of a character in accordance with the feature amount of the inputted character, a size of input character is not limited. Each suitable recognizer is naturally selected in accordance with the feature amount of the inputted character. The input character can be more accurately recognized.

摘要： In a character recognition system for recognising handwritten characters a predetermined characteristic amount is extracted for each stroke of a handwritten character, a characteristic amount word is created having one possibility of a binary value only in one or more bit positions corresponding to the characteristic amount, an AND operation (6) is performed bit-by-bit between the reference word of the corresponding stroke of the character of interest, and an OR operation is performed for all the bits of the results of the AND operation. If the number of binary values of the results of the OR operation for all the strokes of the character of interest exceeds a threshold, it is judged to be a candidate.
摘要翻译：在用于识别手写字符的字符识别系统中，针对手写字符的每个笔划提取预定的特征量，创建具有仅对应于特征量的一个或多个位位置具有二进制值的一个可能性的特征量字， AND操作（6）在相关字符的对应行程的参考字之间逐位执行，并且对AND运算结果的所有位进行OR运算。如果关注字符的所有笔划的OR运算的结果的二进制值的数量超过阈值，则判断为候选。

摘要： Pattern recognition apparatus and method which provides plural pattern recognition modes, one of which is selected in accordance with characteristics of an unknown pattern to be recognized. The pattern recognition apparatus includes a pattern recognizer having plural recognition modes for comparing an unknown pattern with at least one known pattern, and a selector for selecting one of the plural recognition modes based on characteristics of the unknown pattern. In one aspect, the selection of one of the plural recognition modes is based on font size, font type and image quality, and in another aspect, selection of the recognition mode is based on the results of prior pattern recognition operations. The pattern recognition apparatus may be provided in a stand-alone device, and this device may interface to a local area network bus. Alternatively, the pattern recognition apparatus may be distributed such that individual components thereof are provided independently on a local area network bus and provided with individual servers for interface with stand-alone computers. In the case where computers perform character processing or word processing, a preview mode may be provided so that the results of character recognition may be previewed before transmitting image information to a remote location.

摘要： Each row of characters is extracted from document data representing rows of characters by a character raw extracting circuit (13). The characters are separated from the row by a character separating circuit (14). In a reference line detecting circuit (15) two histgrams are formed, one pertaining to the upper sides of the rectangles bordering the extremities of the characters, and the other pertaining to the lower sides of these rectangles. Two reference lines are defined from the histogram. The characters are sorted into several categories, in accordance with their sizes and the positions they take with respect to the reference lines. The pattern of each character is compared with the dictionary patterns of the same category.

摘要： Appareil et procede de commutation dynamique entre des caracteres ou groupes de caracteres typographiques dans un systeme de reconnaissance automatique de caracteres (10). Le vecteur caracteristique que le systeme de reconnaissance produit pour chaque caractere sur un document est normalise en une longueur unitaire (24) et projete sur un ensemble vecteurs caracteristiques ("eigenvectors") (28). Une memoire (26) dans le systeme de reconnaissance de caracteres emmagasine plusieurs ensembles de "vecteurs caracteristiques", chaque ensemble correspondant a une typographie particuliere. Un caractere de commutation qui est inclus entre un premier groupe et un second groupe de caracteres declenche la selection de l'ensemble approprie de "vecteurs caracteristiques" pour la typographie suivante.

摘要： A character recognition device comprising: a storage means storing a plurality of dictionary databases corresponding to each of a plurality of degradation levels, said databases being generated from images wherein an original character image has been degraded using a plurality of different degradation levels; an image input means that receives input of images; an extraction means that extracts character images from said images; a usage order determination means that determines an usage order for dictionary databases on the basis of degradation degrees for extracted character images; and a character recognition means that uses dictionary databases in accordance with said usage order, recognizes characters included in the extracted character image and, if recognition results for the character recognition fulfil prescribed conditions, outputs the recognition results without performing recognition using the dictionary database next in said usage order. As a result, accurate and fast recognition of degraded character images can be performed.

摘要： A device may receive a classification model generated based on a set of spectroscopic measurements performed by a first spectrometer. The device may store the classification model in a data structure. The device may receive a spectroscopic measurement of an unknown sample from a second spectrometer. The device may obtain the classification model from the data structure. The device may classify the unknown sample into a Kosher or non-Kosher group or a Halal or non-Halal group based on the spectroscopic measurement and the classification model. The device may provide information identifying the unknown sample based on the classifying of the unknown sample.
