発明の名称 (英語) OBJECT DETECTION METHOD
発明の概要(英語) Disclosed is an object detection method that is provided with a step for extracting a plurality of reference feature vectors related to a local region from an image representing an object, and extracting a plurality of query feature vectors related to the local region from a search query image; a step for matching each query feature vector against each reference vector, and calculating a similarity score having a value that is higher the closer the distance between both vectors, the larger the local region for which the query feature vector has been extracted, and the larger the local region for which a matching reference vector has been extracted; a step for determining a reference vector for which a similarity score is highest as the similarity vector for each query feature vector; and a step for acquiring a final score by object associated with the similarity vectors, and setting the object returning the highest score as the detection result; and characterized in that the score is calculated by dividing the similarity score for each similarity vector by the number of feature vectors that have matched the object.
