The method of generating a hierarchical structured pattern based descriptor may include generating a hierarchical structured pattern by defining a parent node based on a patch region for a feature point of an input image to be analyzed and defining a child node obtained by dividing the parent node to a predetermined depth, calculating a master direction vector of the patch region based on position coordinates and representative pixel values of the parent node and the child node, and calculating a rotation angle of the patch region based on the master direction vector and rotating the hierarchical structured pattern by the rotation angle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for generating a hierarchical structured pattern based descriptor and method and device for recognizing object using the same","description":"Disclosed are a method of generating a hierarchical structured pattern based descriptor and a method and a device for recognizing an object in an image using the same.
