    • An injection control system of a flocculating agent comprises: a flocculating pool into which the inflow liquid flocculating agent is injected and which forms flocs of suspended matters in the liquid; flocculating agent injecting means for injecting the flocculating agent into the flocculating pool; floc image pickup means for photographing a state of the flocs in the flocculating pool and for converting luminance data of the flocs into an electric signal; image recognizing means for recognizing the shape of floc by binarizing the image signal derived from the floc image pickup means on the basis of a luminance level of each pixel; flocculation state deciding means for calculating a characteristic amount of a diameter distribution of the flocs on the basis of the floc shapes recognized by the image recognizing means; and injection amount control means for controlling an amount of the flocculating agent which is injected from the flocculating agent injecting means on the basis of the characteristic amount.

    • In a case in which handwritten character recognition such as online handwritten character recognition is implemented, simple and high performance character recognition by which transformation such as remarkable transformation and rotation is able to be treated and which recognizes an input that is written in a single stroke such as kaisho-writing, is provided. Because of this, the present invention performs: capturing an input handwritten character with parameter representation for each stroke and applying a polygonal approximation to each stroke; assuming each polygonal line segment approximated by the polygonal approximation to be vector that reaches an end point from a start point, and obtaining an angle between an axis that becomes a reference and each line segment as a polygonal line segment angle sequence; obtaining an exterior angle sequence of vertices of the obtained polygonal line segments; making a sum of exterior angles of the same sign, where the same sign of plus or minus in the exterior angle sequence continues, to be a winding angle sequence; extracting a global feature according to each obtained sequence and a localized or quasi-localized feature in each curved portion divided corresponding to the winding angle sequence, hierarchically and divisionally; and performing the character recognition by comparing the extracted result with a template of an object character for recognition that is provided in advance.

    • An apparatus for recognizing visual patterns of handprinted characters or the like by means of an optical character reader which reads the patterns by a so-called outermost point method. While tracing the contour of the pattern stored in a two-dimensional memory, the distances from the starting point of the tracing and the integrated values of the coordinates of the points traced on the contour from the starting points are simultaneously obtained successively to extract outermost points for the series of contours. According to this outermost points, the contours are segmented into the convex line segments, concavity line segments and hole segments and the corresponding parameters of features of each segment are detected. Simultaneously, the convex line segment of which is shorter than a predetermined length is rejected and the remaining segments are subjected to matching operation in accordance with preliminarily prepared dictionary, thereby making a decision as to the pattern's identity.
    • 用于通过所谓的最外点法读取图案的光学字符阅读器来识别手印字符等的视觉图案的装置。 在跟踪存储在二维存储器中的图案的轮廓时,连续地同时获得跟踪起始点的距离以及从起点跟踪在轮廓上的点的坐标的积分值,以提取最外点 用于一系列轮廓。 根据该最外点,将轮廓分割为凸线段,凹部线段和孔段,并且检测每个段的特征的对应参数。 同时,其凸线段短于预定长度被拒绝,并且根据预先准备的字典对其余段进行匹配操作,从而对图案的身份做出决定。
