Abstract
According to one embodiment, a reading system includes an extractor, a determiner, and a reader. The extractor extracts a candidate image from an input image. The candidate image is of a portion of the input image in which a segment display is imaged. The determiner calculates an angle with respect to a reference line of each of a plurality of straight lines detected from the candidate image, and determines whether or not the candidate image is an image of a segment display based on a distribution indicating a relationship between the angle and a number of the straight lines. The reader reads a numerical value displayed in a segment display from the candidate image determined to be an image of a segment display.
Claims10
A reading system, comprising:
- an extractor extracting a candidate image from an input image, the candidate image being of a portion of the input image in which a segment display is imaged;
- a determiner,
- the determiner detecting end point groups in the candidate image where end points are clustered,
- the determiner calculating vectors connecting adjacent end point groups to each other,
- the determiner determining whether or not the candidate image is an image of a segment display based on at least one of a ratio of sizes of adjacent vectors or an angle between the adjacent vectors;
- and
- a reader reading a numerical value displayed in a segment display from the candidate image determined to be an image of a segment display.
