Abstract
There is provided an image processing device including a feature point extraction unit that extracts feature points from an input image, a feature amount calculation unit that calculates feature amounts of the feature points, an image processing unit that processes the marker image to transform the feature amounts of non-distinguishing feature points into feature amounts of distinguishing feature points when the feature points extracted from a marker image included in the input image are not distinguishing, and a marker image generation unit that generates a new marker image based on the processing result.
Claims11
An image processing device comprising:
- a feature point extraction unit that extracts feature points from an input image;
- a feature amount calculation unit that calculates feature amounts of the feature points;
- an image processing unit that processes the marker image to transform the feature amounts of non-distinguishing feature points into feature amounts of distinguishing feature points when the feature points extracted from a marker image included in the input image are not distinguishing;
- and
- a marker image generation unit that generates a new marker image based on the processing result.
An image processing method in an image processing device, comprising:
- by the image processing device,
- extracting feature points from an input image;
- calculating feature amounts of the feature points;
- processing the marker image to transform the feature amounts of non-distinguishing feature points into feature amounts of distinguishing feature points when the feature points extracted from a marker image included in the input image are not distinguishing;
- and
- generating a new marker image based on the processing result.
A program for causing a computer to function as:
- a feature point extraction unit that extracts feature points from an input image;
- a feature amount calculation unit that calculates feature amounts of the feature points;
- an image processing unit that processes the marker image to transform the feature amounts of non-distinguishing feature points into feature amounts of distinguishing feature points when the feature points extracted from a marker image included in the input image are not distinguishing;
- and
- a marker image generation unit that generates a new marker image based on the processing result.
