Embodiment approach

[0061] First exemplary embodiment

[0062] First, an image to be recognized by the image recognition device according to this exemplary embodiment will be described. figure 1 A front view of an example of a paper (recording medium) formed with an image to be recognized by the image recognition apparatus according to this exemplary embodiment is depicted.

[0063] Such as figure 1 As depicted in, for example, the boundary 30 defining the entire area of ​​the image may be drawn on the paper P on which the image (for example, construction drawing) to be recognized by the image recognition device is formed. The phrase "the boundary that defines the entire area of ​​the image" means an outer frame, frame, etc., that defines the entire area of ​​the image. The boundary that defines the entire area of ​​the image is not limited to figure 1 The rectangular or substantially rectangular frame described in may be a long line in contact with and extending on a watch, figure, etc., or may have ...

Abstract

The invention provides an image identification apparatus and an image identification method. The image identification apparatus includes an extraction unit, an excluding unit, and an identification unit. The extraction unit extracts lines from an image. The exclusion unit excludes from objects to be identified a boundary delimiting an entire area of the image among the extracted lines. The identification unit identifies as an object multiple lines that are among the extracted lines and that are not excluded by the exclusion unit if the multiple lines are connected to each other.

Description

Technical field [0001] The invention relates to an image recognition device and an image recognition method. Background technique [0002] Japanese Patent No. 2940936 discloses a table area recognition method in which columns of black pixels in an image of a document or a compressed image are extracted, and the columns contacting each other are integrated to generate a rectangle. Among the generated rectangles, a rectangle greater than or equal to a predetermined size is determined as the candidate table area. Then, columns included in the rectangle determined as the candidate table area and longer than or equal to a predetermined length are extracted as ruled lines, and it is determined whether the rectangle is a table area according to the number of extracted ruled lines. [0003] Japanese Patent No. 3157414 discloses a document reading device for reading characters from image data of a document having a table. The table in the document has an internal table that includes chara...
