Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention recognizes and processes destination information, which consists of handwritten characters and figures, inputted prior to subtitle mail, as image information, and delivers the original text mail. This invention relates to an image information processing method that generates a delivery management table necessary for the delivery of mail and delivers the original text mail according to the delivery management table.

[Conventional technology]

Conventionally, in facsimiles and mail, methods that enable mail delivery by recognizing handwritten image information as destination information and determining the mail destination can be roughly divided into two types: There is a check mark reading method in which the address is expressed by checking the mark position by hand, and the check mark position is read, and a handwritten method in which the address is identified by reading the characters written on the address sheet that has a specific format. The character reading method was broken.

The former method uses a check mark sheet to express and input the destination by checking it, so it has the advantage of being able to input destination information with high precision when there are few selection items to check, while the latter method Since this is a method of inputting destination information by handwriting common handwritten katakana and alphanumeric characters, it ensures diversity of input information when there are many selection items and description items to express the destination 1.1. It is excellent in that it is possible to

However, with these methods, in order to improve the accuracy of cutting out check marks and characters and maintain recognition accuracy, it is necessary to use a specific destination sheet with detailed formats and filling methods. The drawback is that the cost is high.

Furthermore, when writing destination information (delivery order) such as circulars, circulars, collections, etc. specific to mail destinations, if you try to write such complicated destination information only by writing checkmarks or handwritten characters, it will inevitably be difficult to write. As a practical matter, it would be difficult to describe it, and it would require extra effort on the part of the scribe, so we would like to ease the input writing conditions51! There was hope.

[Problem that the invention seeks to solve]

Therefore, the problem that the present invention aims to solve is to eliminate the need to use expensive specific address sheets to write mail addresses, and to make it unnecessary to write complicated address information such as circulation, opening, and collection. It can be said that the aim is to reduce the amount of labor required.

Therefore, the present invention does not require expensive specific address sheets.
This makes it possible to write complex destinations specific to mail without much effort, and thereby enables the delivery of the original mail (image information (handwritten). The purpose of this service is to provide a method for processing (destination information and original mail information).

[Means and effects for solving the problems] The present invention has the following features:
Prior to the original mail, an address sheet handwritten with letters and figures is input as address information such as the delivery order of the mail, and the address information read from the sheet is recognized and processed as image information, and the original mail is delivered. 5. An image information processing method that generates a delivery management table necessary for the delivery management table and sends the original mail according to it, comprising: means for tracing the outline of a figure in the destination sheet; square marks that constitute the figure by extracting features of bending points of the contour from the results;
The sender character area figure, the recipient character area figure, and the relationship are determined from the means for identifying the figure and the square mark for detecting the inclination that occurs when inputting the address sheet and the size of the characters in the address sheet. A square is generated, and the square is applied to the sender character area graphic in which the sender information is written and the recipient character area graphic in which the recipient information is written, and the characters are written in units of characters. In addition to cutting out and character recognition, the above-mentioned relationship for associating the character area figures and the prints is carried out by a means for determining the relationship between the character area figures based on the figures, and from the character recognition result and the relationship between the character area figures. and means for generating a delivery management table for managing mail delivery by specifying the order, etc., and by referring to the table, the original mail is delivered in a predetermined delivery order. It is characterized by

The transition of each bending index in Le p L f is determined as shown in FIG. 3 (b).

Here, the bending index is defined as (1 + cosl
F), where it takes a value close to 2 in prominent areas, and 0 in flat areas.

The position of the bending point (La-Lf) can be determined conversely from the position of the peak in FIG. 3(c). By providing a threshold K for the bending index, the types of bending points can be classified and the number of each type can be counted.

For example, if (bending index)〉1 is an acute point and 1〉(bending index))0.2 is an obtuse point, then from Fig. 3 middle),
The number of acute points is 5 points a, b, d, e, and f, and the number of obtuse points is 0 points.

Furthermore, it can be determined from the interval between the bending points that point f is the root of the arrow, and point 0, which is the farthest point from point f, can be determined to be the tip of the arrow.

Then, by examining the character area figures close to the f point and the 0 point, the relationship between the character area figures can be determined.
