    摘要: Provided are a feature vector extractor and a recognition device using the same. The feature vector classifier includes a feature vector extractor configured to generate a feature vector and a normalized value from an input image and output the feature vector and the normalized value; and a feature vector classifier configured to normalize the feature vector based on the normalized value and classify the normalized feature vector to recognize the input image. Thus, during extraction and classification of a feature vector, time required for the extraction and classification and the size of hardware required are significantly reduced.

    摘要: Provided is an image matching method of matching at least two images. The image matching method extracts feature points of a reference image and feature points of a target image, changes a feature point, selected from among the feature points of the reference image, to a reference point in the target image, sets a matching candidate region on the basis of the reference point, in the target image, and performs a similarity operation between the selected feature point in the reference image and a plurality of feature points included in the matching candidate region among the feature points of the target image. The image matching method decreases the number of similarity operations performed in the image matching operation, thereby guaranteeing a high-speed operation.
