Abstract
An information processing apparatus detects a line segment from an image, determines whether four sides of a plate are detected based on the detected line segment, calculates an aspect ratio of the detected four sides in a case where it is determined that four sides of the plate are detected, and determines whether the aspect ratio satisfies a first condition. In a case where it is determined that four sides of the plate are not detected, the information processing apparatus searches a vicinity of the detected line segment for an object, and determines whether the object satisfies a second condition. The information processing apparatus judges that a recognition target area is included in the image in a case where it is determined that the first condition or the second condition is satisfied.
