Abstract
According to an embodiment, an image processing device includes one or more processors. The one or more processors are configured to: acquire an image; detect a first repeated pattern from the image; detect an object included in the first repeated pattern; and output the object as a second repeated pattern.
Claims14
An image processing device comprising:
- one or more processors configured to:
- acquire an image;
- detect a first repeated pattern from the image;
- divide the first repeated pattern into a plurality of partial images;
- execute image processing on a first partial image included in the plurality of partial images, and output a processed image;
- perform matching between feature points of a second partial image included in the plurality of partial images and feature points of the processed image, and detect similar feature points as corresponding points;
- determine whether or not the first partial image and the second partial image are repeated patterns based on relative positional relationships between the corresponding points and the corresponding feature points;
- detect the first partial image and the second partial image determined as repeated patterns, as an object included in the first repeated pattern;
- and
- output the object as a second repeated pattern.
