| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | For image recognition with a camera phone, defocus and motion-blur cause a serious decrease of the image recognition rate. In this report, we employ generative learning, i.e., generating blurred images and learning based on them, for a recognition method using approximate nearest neighbor search of local features. Major prob- lems of generative learning are long processing time and a large amount of memory required for nearest neighbor search. The problems become serious when we use a large-scale database. In the proposed method, they are sloved by cascading recognizers and scalar quantization. From experimental results with 10,000 images, we have confirmed that the proposed method improves the recogniton rate by 12.3% as compared to a method without generative learning. |
