Abstract (in Japanese) (See Japanese page) 
(in English) Certain objects that appear in images from the real world often appear together, while other sets of objects rarely appear together. In this paper, we propose an approach to object recognition using the co-occurrence of object categories to obtain an accurate existence ratio of categories in an image. Using a Bag of Feature (BOF) framework, it is assumed that the histogram of the test image can be represented as a linear combination of the histograms of each category. To obtain the existence ratio from an image, we adopt MAP estimation using the learned co-occurrence of multiple categories as the prior probability.
