| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we propose the smoothing method for sequential data using Particle Filter, and apply to NBI video endoscopy. For early detection of colorectal cancer, the recognition technique using Bag--of--Features and SVM is proposed, and extended to NBI video. However, there is a problem that recognition results isn't stabilized because it recognizes independently with each frame. Therefore, we propose the smoothing method for sequential data using posterior probability of SVM with each frame to likelihood of Particle Filter. Experimental results using NBI video shows that we can get more stable results. | |
