| Abstract(in English) | In this paper, our goal is automatic segmentation of object regions which is processed before recognition in Bag-of-Keypoints. Region segmentation, such as Graph Cuts, is useful for object recognition. Objects tend to exist at the center of image, so we give seeds for a center and four corners of an image and apply the first-stage graph cuts to segment along edges. We get a color histogram from the first segmentation results and assign probabilities as the t-link of the graph for the second-stage graph cuts. Bag-of-Keypoints is then applied to the second segmentation results. We demonstrate that we can obtain better results than the case of using only Bag-of-Keypoints method. |
