1. A method for multimedia model retrieval, comprising: acquiring parameters of a first multimedia model to be retrieved; performing a projection on the first multimedia model according to the parameters of the first multimedia model so as to obtain a projection image; performing a feature extraction on the projection image to generate a first feature extraction result; comparing the first feature extraction result with a plurality of feature extraction results corresponding to a plurality of multimedia models stored in a database so as to obtain a retrieval result, wherein the retrieval result comprises a number of multimedia models; labeling by a user each of the multimedia models in the retrieval result with a probability value; training a support vector machine with the labeled multimedia models; performing a probability-based classification on the plurality of multimedia models stored in the database by using the support vector machine to obtain a classification result; and updating the retrieval result with the classification result.
