  • DeepEye: A Dedicated Camera for Deep-Sea Tripod Observation Systems

    Lu H., Li Y., Kim H., Serikawa S.

    Studies in Computational Intelligence    810   507 - 511   2020年01月  [査読有り]

     概要を見る

    © 2020, Springer Nature Switzerland AG. The deep-sea tripod systems are designed and built at the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center (PCMSC) in Santa Cruz, California. They are recovered in late September 2014 after spending about half a year collecting data on the floor of the South China Sea. The deep-sea tripod systems are named as Free-Ascending Tripod (FAT), are deployed at 2,100 m water depth—roughly 10 times as deep as most tripods dedicated to measuring currents and sediment movement at the seafloor. Deployment at this unusual depth was made possible by the tripod’s ability to rise by itself to the surface rather than being pulled up by a line. Instruments mounted on the tripod took bottom photographs and measured such variables as water temperature, current velocity, and suspended-sediment concentration. FAT is used to better understand how and where deep-seafloor sediment moves and accumulates. Besides of this, we also use them to study the deep-sea biology. The obtained the images from the camera, the biology animals are hardly to be distinguished. In this project, we are concerned to use novel underwater imaging technologies for recovering the deep-sea scene.

     概要を見る

    © 2019 IEEE. Surface-Defect segmentation plays an important role. It is very necessary to detect on products during production process. Though there are several previous works in surface-defect segmentation, it needs high handcraft skill. We address automatic segmentation algorithm in surface using U-shape inverted residuals to achieve end-to-end learning network. A proposed method is data acquisition, surface-defect segmentation network creation and training. First, the experimental image is augmented by image processing technique, such as rotation, flip, translation, skew and zoom in, which is randomly augmented. Second, U-shape inverted residuals segmentation network is created by changing backbone of encoder and reconstructs decoder by inverted of encoder in order to improve performance of segmentation network. In the final step, the training step of the proposed network is set. To evaluate the performance of the proposed network, each plastic hose tip and dental caries 10, 000 image are used to compare between proposed network and Unet [15]. From the experiment, Dice score and IoU are 77.11% and 62.75% in plastic hose tip, respectively. In dental caries problem, Dice score and IoU are 84.16% and 72.65%, respectively. The results show that the proposed network is satisfactory and able to be improved for higher performance. Advantages of the method are that it avoids handcraft feature extraction and is automatically learning.

  • Touch switch sensor for cognitive body sensor networks

    Li Y., Lu H., Kim H., Serikawa S.

    Computer Communications    146   32 - 38   2019年10月  [査読有り]

     概要を見る

    © 2019 Elsevier B.V. With the global popularity of Internet of Things (IoT) technology, increasingly numbers of digital mobile products have been developed, and they have increased the productivity of people's daily lives. These electronic products are used in all aspects of life, such as medical care, office life, home services, and sports. However, most of these products are designed for healthy people with high literacy rates. For disabled people, these products cannot be widely used. In this paper, new, differently shaped touch sensors are proposed for body sensor network-based devices. This touch sensor can be formed into any shape because of the use of conductive fabric adhesive tape as a switch. That property is why the sensor can change positions in the body sensor network in which the human body is used as a trigger to safely activate the touch switch. The number of switch sensors can easily be increased or decreased without changing the wiring of the central controller. The number of sensors in a switch sensor system is greater than that in other touch switch systems, and the accuracy is higher.

  • CONet: A Cognitive Ocean Network

    Lu H., Wang D., Li Y., Li J., Li X., Kim H., Serikawa S., Humar I.

    IEEE Wireless Communications    26 ( 3 ) 90 - 96   2019年06月  [査読有り]

     概要を見る

    © 2019 IEEE. The scientific and technological revolution of the Internet of Things has begun in the area of oceanography. Historically, humans have observed the ocean from an external viewpoint in order to study it. In recent years, however, changes have occurred in the ocean, and laboratories have been built on the sea floor. Approximately 70.8 percent of the Earth's surface is covered by oceans and rivers. The Ocean of Things is expected to be important for disaster prevention, ocean resource exploration, and underwater environmental monitoring. Unlike traditional wireless sensor networks, the Ocean Network has its own unique features, such as low reliability and narrow bandwidth. These features will be great challenges for the Ocean Network. Furthermore, the integration of the ocean network with artificial intelligence has become a topic of increasing interest for oceanology researchers. The cognitive ocean network (CONet) will become the mainstream of future ocean science and engineering developments. In this article, we define the CONet. The contributions of the article are as follows: a CONet architecture is proposed and described in detail; important and useful demonstration applications of the CONet are proposed; and future trends in CONet research are presented.

    ACM International Conference Proceeding Series      2019年05月  [査読有り]

     概要を見る

    © 2019 Association for Computing Machinery. The purpose of this study is to develop a device that can make the choreography of dance easily. Since ancient times, people have given meanings and various purposes to dance as an action to music such as expressing emotions, praying to God, and transmitting traditional history. The research why people dance [1] leads us to the conclusion: people dance in order to convey what they can not tell with words. The messages of dance has not been changed until today. Dancing is recognized as the simplest means of communication. When we dance, we do not need words, and dancing is expected to offer opportunities of communication and to improve communication skills[2]. a large-scale tournament is held as a sport, Such as baseball and volleyball, and the participants and the audiences from all over the world are impressed. Like this way, dancing also touches people’s hearts. And probably everyone knows how wonderful dancing is. There are 6 million people doing street dance in Japan and street dance has high popularity and status[3]. Japanese Ministry of Education announced the martial arts and dance class are compulsory in a junior high school in March 2008 [4],. and they said “Dance is one of the exercises to communicate with friends through exchanging expressions and movements and change image. It is recognized as a movement that we can enjoy feeling emotion with others, capturing images and expressing oneself.” This is why Japanese Ministry of Education regard dancing as a required subject. From these facts, it is obvious that dance is familiar to anyone and it is enjoyed by all ages, genders and tribes all over the world. In order to dance, " Choreographer of the dance" is very important. The choreographer is the subject of this research. Now, the dance has become more familiar, and dance production will inevitably become more familiar. It is one of the good examples that the martial arts and dance are compulsory in junior high school described above. The dance classes in the elementary school mainly focus on learning personal skills such as capturing the characteristics of rhythms and dances. But in junior high school, the dance classes mainly focus on group learning and team learning. And it aims at communication and presentation through the process of deepening the expression in dancing. [4]. To make a presentation, making choregraph is necessary. There are another scene that the creative dance is required such as stage appearances at cultural festivals and events at banquets. They are familiar to us. Although creating dance has become familiar, creating dance is not easy for amateur students and adults. So they cannot create dance right away, and some training is required. I think that there are some solutions to overcome by developing application in choregraphing dance. The procedures for choreographing dances at entertainments and cultural festivals are mainly described as follows [5]. 1. Define for whom to dance. 2. Define the place to dance. 3. Choose a song to use. 4. Find videos to help you choreograph. 5. Move in front of the mirror to check. 6. Write down the choreograph on paper to record it. Steps 1 to 3 are the foundations for the choreographer. The procedure will determine the direction of choreography. Step 4 is a search for choreography that fits the direction defined in step 3. It is difficult to design every choreography from the beginning without dance experience. Therefore, it is often used to find videos of experienced dance creators. Step 5 is to confirm and correct the choreography.. Step 6 is to make a dancing score to explain the choreography to others while making sure to remember the choreography that you created. The goal of this study is to develop an application or tool that can solve the complains in these procedures and increase the efficiency. Therefore, in this research, we have decided to take up two points. One of these is in Step 5: "I can’t see the movement by myself" and the other is in Step 6 "I forget the choreography I created". The reason we focused on the two points is that dance is difficult to remain as a form comparing other general creation. If the suggestion for dance choreography can be actually confirmed, checking at the mirror will not be necessary, and at the same time there will be no worries about forgetting choreography. Therefore, It can be expected to omit steps 5 and 6. From these things, the purpose of this research is to make dance formable and simplify the creation of choreography by developing an application that saves and reproduces choreography of dance for students who are not familiar to dance production. The following applications and tools have already existed. Standing position creation application "daisy beat" that can register the standing position of the dancer in each scene [7]. Step 2 and step 6 can be improved. You can create a dance score which can express a pose with a stickman. Dance score creation application "odorifu" [8]. Step 6 can be improved. A dance video search application "choreograph master dance!" [9]. Step 4 can be improved.

    目的地点まで正しく移動することが搬送ロボットの最も基本的な仕事である。今まではカメラを用いてランドマークの位置を認識しながら移動する方法が多く提案されているが、認識率が100%でない。業務用ロボットの場合、誤認識は許されない。一方、床にテープや磁気テープを貼り、それにしたがって移動するライントレーサ方式がシンプルかつ認識が確実であり(1)、産業上多くの場面で使用されている。しかし、この方法では経路を変更することが容易でない。そこで、ライドマーク自体が発光するアクティブランドマークとその方向をカメラで認識する方法が提案された(2)。この方法は経路変更が容易で、ランドマークの認識率も高いが、認識率100% には達しない。また、外乱光の変化による対応できない場合がある。本研究では、より確実にアクティブランドマークの方向を検知するためのLED による方向検知方法を提案する。この方法は認識率100%で外乱光にも強い。

    We continued to improve our previous research. It is improvement of the system which automatically detects fire and performs initial fire fighting. This system is attached to the digestive device of existing products. In this system, the nozzle is automatically directed to the fire position and automatically extinguished if it is judged to be a fire. Infrared cameras are used to judge fire, fire is determined by image processing. After extinguishing the fire, the fire information is transmitted to the smartphone via the user. In this paper, we improved this system. As a result, by installing a fire extinguisher on the ceiling, it was possible to detect a wider range of fires and extinguish the fire.
