Abstract(in English) | Recently automatic image annotation (AIA) receives a lot of attention in the fields of information retrieval, and many ideas have been proposed over this decades. Semantic Multi-Class Labeling (SML) is the representative example, based on a Naive Bayes classifier with local image features whose existing probabilities are estimated by gaussian mixture models. However there is such a difficult problem that SML requires its long training time and annotation time, when a posterior distribution of each label is estimated. To deal with this problem, instead of gaussian mixture models, we introduce a Random Forest classifier into the AIA task. We have evaluated our method by using a standard image corpus. We show that the speed of annotating by our method is about 50 times faster than by SML, with maintaining the same performance as the existing ideas. |
