2. Real-Time System for Horizontal Asymmetry Analysis on Facial Expression and its Visualization

Ryoichi Shimada, Taro Asada, Yasunari Yoshitomi, Masayoshi Tabuse
Pages: 7 - 11
We report on the development of a real-time system for facial expression horizontal asymmetry analysis and visualization. In this system, the image signal input from a webcam is analyzed using OpenCV, and feature parameters (facial expression intensity) are measured separately for the left and right...

3. A New Machine Learning Algorithm for Weather Visibility and Food Recognition

Young Im Cho, Akmaljon Palvanov
Pages: 12 - 17
Due to the recent improvement in computer performance and computational tools, deep convolutional neural networks (CNNs) have been established as powerful class of models in various problems such as image classification, recognition, and object detection. In this study, we address two fundamentally dissimilar...

4. Development of Dam Inspection Underwater Robot

Hiroyasu Hirai, Kazuo Ishii
Pages: 18 - 22
The maintenances of social infrastructures such as dams and bridges are important subjects. The older the infrastructure becomes, the more need there is for effective inspection methods. In the inspection of the underwater dam structure, divers can be used, but the inspection result is insufficient....

5. A Framework for Haiku Generation from a Narrative

Takuya Ito, Takashi Ogata
Pages: 23 - 26
The primary goal of the authors’ research related to the generation of narratives and haikus is to complete a mutual transformation mechanism between a narrative and a haiku. In this work, the authors propose a framework for transforming a narrative into haiku. The paper shows a basic method of generating...

6. Novel Mathematical Modeling and Motion Analysis of a Sphere Considering Slipping

Kenji Kimura, Kouki Ogata, Kazuo Ishii
Pages: 27 - 32
Many mobile robots that use spherical locomotion employ friction-drive systems because such systems offer omnidirectional locomotion and are more capable of climbing steps than omni-wheel systems. One notable issue associated with friction-drive systems is slipping between the sphere and the roller....

7. Design of a Performance-Adaptive 1-Parameter Tuning PID Controller

Yoichiro Ashida, Shin Wakitani, Toru Yamamoto
Pages: 33 - 37
Many self-tuning Proportional–Integral–Derivative (PID) controllers have been proposed. However, these methods are rarely employed to actual systems because of low reliability of an on-line PID parameter estimator. In this work, a performance adaptive controller that has two stages of PID parameters...

8. Image Processing for Picking Task of Random Ordered PET Drinking Bottles

Chen Zhu, Takafumi Matsumaru
Pages: 38 - 41
In this research, six brands of soft drinks are decided to be picked up by a robot with a monocular Red Green Blue (RGB) camera. The drinking bottles need to be located and classified with brands before being picked up. The Mask Regional Convolutional Neural Network (R-CNN), a mask generation network...

9. Possible Mechanism of Internal Visual Perception: Context-dependent Processing by Predictive Coding and Reservoir Computing Network

Hiroto Tamura, Yuichi Katori, Kazuyuki Aihara
Pages: 42 - 47
The predictive coding is a widely accepted hypothesis on how our internal visual perceptions are generated. Dynamical predictive coding with reservoir computing (PCRC) models have been proposed, but how they work remains to be clarified. Therefore, we first construct a simple PCRC network and analyze...

10. Disaster Area Detection from Synthetic Aperture Radar Images Using Convolutional Autoencoder and One-class SVM

Shingo Mabu, Kohki Fujita, Takashi Kuremoto
Pages: 48 - 51
In recent years, research on detecting disaster areas from synthetic aperture radar (SAR) images has been conducted. When machine learning is used for disaster area detection, a large number of training data are required; however, we cannot obtain so much training data with correct class labels. Therefore,...

11. The Recognition and Implementation of Handwritten Character based on Deep Learning

Fengzhi Dai, Zhongyong Ye, Xia Jin
Pages: 52 - 55
This paper mainly focuses on the recognition of Chinese handwritten characters. By using the deep learning technology, a deep convolution neural network (CNN) is constructed to identify the handwritten character set, and finally gets the network structure that can be used for recognition. By comparing...
