249 results about "Character group" patented technology

In mathematics, a character group is the group of representations of a group by complex-valued functions. These functions can be thought of as one-dimensional matrix representations and so are special cases of the group characters that arise in the related context of character theory. Whenever a group is represented by matrices, the function defined by the trace of the matrices is called a character; however, these traces do not in general form a group. Some important properties of these one-dimensional characters apply to characters in general...

System, process and software arrangement for recognizing handwritten characters

A process and system are provided for determining a most likely combination of characters. In particular, character data which includes information indicative of at least one handwritten character is obtained. The character data includes at least one set of segmentation points for the handwritten character. Then, a score can be provided for each particular character of a set of previously stored characters based on a comparison between the character data and the previously stored particular character. In addition, it is possible to compare visual aspects of the handwritten character to visual aspects of each of the previously stored characters for determining likely characters. Also, a Fisher Matching procedure can be used on the character data to ascertain the likely characters. A plurality of handwritten characters can include a first character that is connected to a second character of the handwritten characters via a ligature. A further score of the ligature can be determined based on a starting point of the ligature and an ending point of the ligature. Furthermore, the first character can be connected to the second character via a transition. A particular score of the transition can be ascertained based on a difference in length of the first character and the second character. This particular score can be combined with a score corresponding to the particular handwritten characters.

Method and matrix for inputting symbols into computers

The invention relates to digital devices, employing a reduced keyboard for text entering. The technical effect of the invention is solving ambiguity of depressed key sequence by using disambiguation system at character level, minimizing a number of entered keystrokes, raising efficiency of inputting both broadly used and special characters of various languages and enabling a user to enter texts by using a touch typing system. Characters 5 of the alphabet are divided into groups 21, 22, 23, depending on its frequency of occurrence in the actual texts. Any character 5 of group 21, comprising “high-frequency” character, is entered by one key-press. As for characters of other groups 22, 23, it is required to select a relevant group 22 or 23, first, and then select a character 5 of same group. Depending on a number of characters in the alphabet and keys on the reduced keyboard, the character groups are split to multiple subgroups 24 (comprising 2-3 characters each). The images of characters 5 of groups 21, 22, 23 are displayed on the screen 3 adequately to topology of key layout of the reduced keyboard 1, allocated to said characters 5. When switching over to group 21, 22, 23, the images of characters 5 are simultaneously modified. The arrangement of characters 5 of the selected language on keys of the reduced keyboard 1 within each group 21, 22, 23 is carried out based on the technology of utmost layout matching to topology of the conventionally adopted layouts of the complete computer keyboard employed for the relevant language. The matrix 20 is designed to arrange the selected language characters, referred to one group (subgroup), on the fields of group 21, 22, 23 (subgroup 24) congruently to topology, their geometrical location on the complete computer physical keyboard, for example, PC keyboard. The matrix 20 may have an alternative embodiment, for example, with reference to FIG. 10, which displays both mathematical 27, and letter 5 characters of a randomly selected language. The drawing on FIG. 1 is attached to accompany the abstract.

Number plate identification method under strong interference environment on basis of complex network theory

The invention discloses a number plate identification method under strong interference environment on the basis of the complex network theory, comprising the following steps: firstly, carrying out quick binarization on a number plate image with a self-adaption multi-threshold method based on blocks and gray characteristic lines; accurately positioning and cutting characters in the number plate image by a number plate priori knowledge with a territory marking method; finally, extracting a character skeleton characteristic; building the complex network model of the character skeleton; describing the character skeleton based on a dynamic-evolution complex network degree characteristic so as to identify characters with a characteristic template matching method; and combining the characters to obtain the number plate. The method disclosed by the invention can avoid influence on the number plate image by strong interferences, such as uneven illumination, changes in the weather, contaminated number plate, inclined number plate, rivet adhesion, image blurring and the like, and has the advantages of strong antijamming capability and robustness, high recognition rate and high speed and is simple to realize.

Character Input Device, Character Input Device Control Method, and Information Storage Medium

To provide a character input device allowing a user to smoothly carry out a “character input operation which is carried out by initially selecting any character group from a plurality of character groups each corresponding to a plurality of characters, then selecting any character from among those corresponding to that group, and determining the selected character as an input character”. The display control unit (140) causes display means to display a character input screen which contains character group correspondence images corresponding to the plurality of character groups, and an input candidate presentation image for presenting characters corresponding to the focused character group, in which the character group correspondence image corresponding to the focus character group is distinctively displayed, and the character specified as a currently selected input candidate among the characters set corresponding to the focused character group is distinctively displayed in the input candidate presentation image. The input character determination unit (138) determines the character specified as the currently selected input candidate as the input character according to an input character determination operation.
