Most of the current inertial positioning systems can be categorized as the strapdown algorithm and the step-and-heading approach. However, for the strapdown algorithm using smartphone as a sensor device, the accuracy of the current MEMS based accelerometer are not enough for estimating relative movement. Also, for the step-and-heading approach, robust estimation of step length is always difficult. In this paper, we propose an end-to-end walking speed estimation method using Deep Learning to overcome these problems. By using our method, we can achieve a smartphone PDR with higher accuracy and better robustness to gait type.

This paper proposes a platform, called Kugenuma Happy Board, that strengthens communication among elderly in local community for mutual watch-over among them. The platform motivates users to join the mutual watch-over leveraging health-related data acquired from a personal area network (PAN), sharing selfy pictures of smiley face among community, and gamification techniques including missions, scoring, and rankings. We have conducted an in-the-wild experiment for 10 months in Fujisawa Kanagawa, Japan. The experiment showed that the platform accelerates information sharing thus mutual watch-over among users. Particularly, we have observed that elderly users perceived other users activity from shared information, such as step counts and selfy pictures, thus strengthened human relationship in the local community.

Can we inspect the road condition at a low cost? City infrastructures, such as roads are very important for citizens to their city lives. Roads require constant inspection and repair due to deterioration, but it is expensive to do so with manual labor. Meanwhile, there are official city vehicles, especially garbage trucks that run through the entire area of a city every day and have cameras to record their driving. When we use these cameras, we can watch roads conditions anytime, anywhere. In our study, we focus on these cameras and attempt detecting the road damage, such as road marking blur. To achieve our goal, we explore the new system in this paper. This system adopts the object detection approach that is end-to-end learning and based on deep neural networks, which propose the blur region candidate and detect whether the road markings are blurred or not all at once. In our experiment, first, we obtain the drive recorder video from sanitation engineer and then annotate them. After annotation, we trained our models and calculate the mean average precision to evaluate our models. As a result, our model performs on our collected dataset.

<p>In order to encourage elementary school students unfamiliar with Japanese calligraphy to have an assertive attitude towards acquiring basic calligraphy skills, it is imperative to have an application that provides an environment which allows them to practice calligraphy regardless of the time and place. Due to the fact that this application requires an evaluation system that does not need a calligraphy teacher's assistance, this research proposes a method of automatically evaluating a work of calligraphy. All detected strokes within one sheet will be regarded as an object detection problem, therefore, the entire work's evaluation will depend on the detected strokes. Strokes are a fundamental technique in calligraphy, and are a vital component in creating a work of calligraphy.</p>

<p>観光地でのIT導入があまり進んでおらず、ITを導入することで改善される問題は多く存在する。例えば、観光地などで人物カウントを自動で行うシステムを導入することによって、観光地の集客力を定量的に分析することが可能となる。本研究では、広域の観光地を捉えた高解像度の画像から人物をカウントする手法を提案する。人物カウントのシステムの先行研究は複数存在するが、いずれも狭域を捉えた画像を扱っている。広域を捉えた画像は、人がいないエリアが、人がいるエリアよりも大きく、不均衡なデータである。我々の提案手法では、CNNを用いた密度推定に、サンプリングアルゴリズムを導入することによってデータの不均衡性に対処した。この手法の有効性を示すために、江ノ島の海岸を捉えた画像をデータセットとして用いて実験を行ったところ、既存手法を上回る精度を出すことができた。</p>
