Various indoor navigation methods have been developed recently, but digitalized data of indoor map is not always available. Therefore, an indoor navigation framework using an image of information board has been proposed. In this method, the process to extract map regions from the image of an information board is necessary to be done by hands beforehand, and the process to estimate passageway regions...
This paper presents a novel method for structural data recognition using a large number of graph models. Broadly, existing methods for structral data recognition have two crucial problems: 1) only a single model is used to capture structural variation, 2) naive classification rules are used, such as nearest neighbor method. In this paper, we propose to strengthen both capturing structural variation...
This paper describes an adaptive deblocking postfilter based on neural networks for use in H.265 High Efficiency Video Coding (HEVC). Blocking noise is a common problem in video coding caused by the division of the frame into blocks. The filter is adaptive because it uses different filter parameters depending on block characteristics. We use a modified HEVC decoder to export the block information...
In this work, we propose a method for estimating the user's gazing point in the environment using images taken by an eye tracker and an omnidirectional camera. The proposed method estimates the eye positon in environment by mapping the gazing point obtained by the eye tracker in the omnidirectional camera image. However, matching the omnidirectional image and the eye tracker image is difficult because...
Improvement of character recognition technology brings us various character recognition applications for mobile camera. However, many low-resolution and poor-quality character images exist due to the performance of the camera or the influence of environment, and existing methods are not good at recognizing those low-resolution characters. Therefore, we develop a character recognition system for ultra-low...
In this paper, we propose a fast method for extracting a representative graph from decorative character images. The representative graph is an effective method to describe structure information of a graph class. However, the computation time of existing methods for extracting a representative graph is extremely expensive. They search all combinations of nodes of a class. The proposed method calculates...
