Abstract: PROBLEM TO BE SOLVED: To provide technology which can stably discriminate a document by generating a stable virtual page mark even for a non-OCR document.
SOLUTION: To detect the virtual page mark, a key segment which can stably be detected in the document is previously defined and on the basis of the key segment, the virtual page mark (circumscribed rectangle) is generated. Redundancy is given to the detection of the key segment and even if the key segment can not be detected because of a stain, absence, etc., an alternative segment is defined to generate the virtual page mark on the basis of the alternative segment. The selected key segment meets conditions; (1) a segment which is thick enough to be tolerant of faintness of the document, (2) a segment which is at a sufficient distance from the circumference of the document and stable against skew and the absence of a document end, and (3) a segment which does not overlap with a fold of the original paper of the document.

Abstract: PROBLEM TO BE SOLVED: To enable the specification of a character frame and character recognition of a business form without a page mark and a reference mark even with a scanner incapable of detecting an edge of the business form and to simultaneously increase the speed of a discrimination processing of a bit map image by comparing images based on a externally contacted rectangle, etc., formed from horizontal segments capable of being detected at high speed. SOLUTION: When the bit map image including the horizontal segments like character frames 323, 327 and ruled lines 301, 303 on the business form is discriminated as in the case that the business form 300 with the black character frame and without the page mark is discriminated and the character is recognized by an OCR, the horizontal segments are extracted as characteristics of the business form, the circumscribed rectangle 350 is formed in an area to be generated from the horizontal segments and the circumscribed rectangle 350 is defined as information to discriminate an estimation standard of a position of the character frame and a kind of the business form. Even the business form without the page mark and the reference mark is recognized by adapting the information to the OCR. In addition, the business form is more exactly discriminated by comparing the extracted horizontal segments themselves with the horizontal segment of a preliminarily registered business form definition body and comparing similarity.

Abstract: PROBLEM TO BE SOLVED: To detect the most proximate point at high speed with high precision. SOLUTION: A characteristic space is divided into groups for every characteristics more than one or two and it is discriminated whether a distance value calculated in each group exceeds a threshold THR-MIX for each group or not. In this case, the THR-MIX is set at the average value of a threshold set, based on a cumulative characteristic amount and a threshold set, based on a dimensional number. When the distance value for each group exceeds the threshold THR-MIX, the first phase of screening is performed for excluding a prototype applying this distance value from the following distance calculation. Further concerning the group as the object of the first phase of screening, a threshold THR-RATE is calculated from the minimum, value of distance value to that group and the second phase of screening is performed.

Abstract: PURPOSE: To shorten a processing time without deteriorating detecting precision by calculating pixel distribution by scanning picture elements in each range, detecting the positions of the up and down and right and left inside walls of a character frame based on each pixel distribution, and separating the character frame from the image data in the character frame based on the inside walls of the character frame. CONSTITUTION: A scanner 12 scans while a paper is irradiated with a white light, quantizes the intensity of the reflected light, converts an original image 11 into digital image data, and inputs the data through a scanner I/F control circuit 14 to a CPU 16. Pixel distribution in each range is calculated by the range setting means of the CPU 16, and the positions of the up and down and right and left inside walls of the character frame are detected by an inside wall detecting means based on each calculated pixel distribution. The character frame is separated from the image data in the character frame based on the detected inside walls of the character frame. Thus, a processing time can be sharply shortened without deteriorating detecting precision.

Abstract: PURPOSE: To enable a user to easily describe a tree and also to generate a data structure showing the tree in a memory by showing the attributes to be given to the nodes of the tree in every type of them. CONSTITUTION: A table contains the columns of the levels (depth), the node type names and plural attributes, and a user writes the necessary information into these columns. For example, 0 is written in the level column for a node A that is positioned at the highest part of a tree together with 1 written for nodes B to E as the children of A and the sequence relation of the children reflected on the upper-lower relation respectively. The number of nodes, for example, is written in the attribute column, and a tree shown by this table includes the nodes belonging to the types B to E as the children of the node A as long as both maximum and minimum value are set to 1. In other words, the pointer data can be generated through such interpretation as mentioned above and the user can easily input the pointer data by means of a text editor.

Abstract: PURPOSE: To improve the efficiency at recognition time by generating a recognition dictionary in tree structure which considers redundancy by using not binary feature quantities such as whether a pixel is black or white, but multi-valued feature quantities having maximum and minimum values. CONSTITUTION: A system consists of a personal computer 1, a bit map display 2, a scanner 3 and an auxiliary storage device 4, and a recognition part 5, a postprocessing part 6, and a user interface part 7 which are encircled with a broken line are actualized as software. Then the tree-structured dictionary is searched by using a multi-valued feature quantity extracted from an unknown input character pattern, an upper-limit or lower-limit value is assigned to at least one branch in the tree-structured dictionary, and the search of the tree- structured dictionary is quit when the multi-valued feature quantity extracted from the unknown input character pattern for the branching deviates from the upper-limit or lower-limit value. Consequently, the tree-structured dictionary need not be searched unnecessarily and a character can be recognized fast.

Abstract: PROBLEM TO BE SOLVED: To increase the processing speed when the outline of a figure is smoothed by performing the smoothing process by using only logical operation without using 'if then else' or 'switch' syntax of a conditional judgement and a branch instruction as an element causing a decrease in the processing speed. SOLUTION: Process units (t bits) are put one over another, a pattern (process object s bits) for writing a process result is loaded in the center part of an (r)-bit regsiter, and contiguous patterns of a source image are loaded to right and left adjacent parts and processed. Here, a process unit (t) consists of 64 bits the process object (s) which is processed and written consists of 48 bits. When a figure and characters drawn in a bit pattern is smoothed, not the if then else' or 'switch' syntax of a conditional judgement and a branch instruction as an element causing a decrease in process speed, but only logical operations for shifting a bit array, NOT, AND, OR, etc., are used to perform a process for smoothing.
