20 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...

A control portion recognizes, as an independent character region, a region of which the absolute value of the difference between the width in a first direction, which is the writing direction, and the width in a second direction, which is orthogonal to the first direction, is smaller than a first threshold value, and checks, based on the width in the first direction of a reference region that is a character region adjacent, in the second direction, to a plurality of independent character regions aligned in the first direction but that is not an independent character region, whether a character string composed of characters in the plurality of independent character regions is one word. On judging it to be one word, the control portion deals with the character string resulting from uniting the characters in the plurality of independent character regions as one word.
