Abstract
A method of recognizing a specific image includes detecting image features from the specific image and storing in a memory each of detected relevant image features, detecting relevant image features from an input image and selecting from the memory a portion corresponding to each of the detected relevant image features, generating a restoration image using portions selected in the selecting, and determining whether the generated restoration image matches with the input image by a matching process and recognizing that, when it is determined that the restoration image matches with the input image, the input image is the specific image.
Claims16
An image recognition method of recognizing a specific image, the method comprising:
- a first step of detecting a plurality of relevant image features from the specific image and storing in a memory each of the detected relevant image features as a portion;
- a second step of detecting a plurality of image features from an input image and selecting from the memory the portion corresponding to each of the detected relevant image features;
- a third step of generating a restoration image by using a plurality of portions selected in the second step;
- and
- a fourth step of determining whether the restoration image generated in the third step matches with the input image by a matching process and recognizing that, when it is determined that the restoration image matches with the input image, the input image is the specific image.
An image recognition device to recognize a specific image, the image recognition device comprising:
- a memory to store therein each of a plurality of image features detected from the specific image as a portion in advance;
- a feature detector to detect a plurality of relevant image features from an input image;
- a restorer to select from the memory the portion corresponding to each of the relevant image features detected by the feature detector and to generate a restoration image by using a plurality of selected portions;
- and
- a determiner to determine whether the restoration image generated in the restorer matches with the input image by a matching process and to recognize that, when it is determined that the restoration image matches with the input image, the input image is the specific image.
