Abstract:
A method of retrieving moving pictures using joint points based on pose information, comprising the steps of:extracting and expressing joint points of a joint point model existing in moving pictures or still pictures which are the object of retrieval by using an indexing apparatus and a retrieving apparatus based on a joint point model; and retrieving a person which is an object of retrieval according to the joint points extracted from said indexing apparatus by using a retrieving apparatus based on a joint point model, wherein said retrieving apparatus comprises: joint point model based user query input and retrieval result interface for providing joint points information and their related information which allow a user to find a desired person which is an object of retrieval or providing the retrieval result screen to the user; joint point model based query point representing means for representing the joint points input through said joint point model based user query and retrieval result interface; moving picture/still picture data and indexing information storage for storing the representative pictures or still pictures which are higher in a total similarity degree in consideration of weighted values per respective similarity degree which is defined by the user; similarity degree measuring means between query/person object for performing similarity degree measurement on various characteristics between the person object input by the query on the basis of the joint points represented from said joint point model based query joint point representing means and the indexing information stored at said moving picture/still picture data and indexing information storage; and similarity degree analysis and picture extracting means for performing a similarity degree measurement from the value of similarity degree per respective characteristics which are measured from said similarity degree measuring means between query/person object and the indexing information which is stored at said moving picture/still picture data and indexing information storage, and sending the results to the user through said joint point model based user query input and retrieval result interface.
