Innovation and rapid increased functionality in user friendly smartphones has encouraged shutterbugs to have picturesque image macros while in work environment or during travel. Formal signboards are placed with marketing objectives and are enriched with text for attracting people. Extracting and recognition of the text from natural images is an emerging research issue and needs consideration. When compared to conventional optical character recognition (OCR), the complex background, implicit noise, lighting, and orientation of these scenic text photos make this problem more difficult. Arabic language text scene extraction and recognition adds a number of complications and difficulties. The method described in this paper uses a two-phase methodology to extract Arabic text and word boundaries awareness from scenic images with varying text orientations. The first stage uses a convolution autoencoder, and the second uses Arabic Character Segmentation (ACS), which is followed by traditional two-layer neural networks for recognition. This study presents the way that how can an Arabic training and synthetic dataset be created for exemplify the superimposed text in different scene images. For this purpose a dataset of size 10K of cropped images has been created in the detection phase wherein Arabic text was found and 127k Arabic character dataset for the recognition phase. The phase-1 labels were generated from an Arabic corpus of quotes and sentences, which consists of 15kquotes and sentences. This study ensures that Arabic Word Awareness Region Detection (AWARD) approach with high flexibility in identifying complex Arabic text scene images, such as texts that are arbitrarily oriented, curved, or deformed, is used to detect these texts. Our research after experimentations shows that the system has a 91.8% word segmentation accuracy and a 94.2% character recognition accuracy. We believe in the future that the researchers will excel in the field of image processing while treating text images to improve or reduce noise by processing scene images in any language by enhancing the functionality of VGG-16 based model using Neural Networks.

This paper discusses the method of vision based sensor fusion system for biped robot walking. Most researches on biped walking robot have mostly focused on walking algorithm itself. However, developing vision systems for biped walking robot is an important and urgent issue since biped walking robots are ultimately developed not only for researches but to be utilized in real life. In the research, systems for environment recognition and tole-operation have been developed for task assignment and execution of biped robot as well as for human robot interaction (HRI) system. For carrying out certain tasks, an object tracking system using modified optical flow algorithm and obstacle recognition system using enhanced template matching and hierarchical support vector machine algorithm by wireless vision camera are implemented with sensor fusion system using other sensors installed in a biped walking robot. Also systems for robot manipulating and communication with user have been developed for robot.

This paper studies legal regulation of the public policy exception in the Russian Federation and domestic judicial practice on the issue. It reviews current legislation and analyzes a number of recent court cases where an arbitral award rendered by a foreign arbitration body was refused recognition and enforcement based on public policy violation. By doing so, it contributes to the knowledge on the concept of public policy in the Russian legal system and how public policy can affect the process of recognition and enforcement of foreign arbitral awards on its territory. The review of court cases demonstrates different aspects of how the public policy exception can be applied by Russian arbitrazh courts. Such decisions can provide a clearer picture of the kinds of situation that can lead to invoking the public policy clause by the court. Also, it is of practical value as persons preparing to file a claim or to be a defendant in a Russian court can be required to present existing court decisions in support of their claim or defence.

A scenario known as conflict in face recognition may arise as a result of some disparity-related issues (such as expression, distortion, occlusion and others) leading to a compromise of someone's identity or contradiction of the intended message. However, addressing this requires the determination and application of appropriate procedures among the various conflict theories both in terms of concepts as well as resolution strategies. Theories such as Marxist, Game theory (Prisoner's dilemma, Penny matching, Chicken problem), Lanchester theory and Information theory were analyzed in relation to facial images conflict and these were made possible by trying to provide answers to selected questions as far as resolving facial conflict is concerned. It has been observed that the scenarios presented in the Marxist theory agree with the form of resolution expected in the analysis of conflict and its related issues as they relate to face recognition. The study observed that the issue of conflict in facial images can better be analyzed using the concept introduced by the Marxist theory in relation to the Information theory. This is as a result of its resolution strategy which tends to seek a form of balance as result as opposed to the win or lose case scenarios applied in other concepts. This was also consolidated by making reference to the main mechanisms and result scenario applicable in Information theory.

This paper describes the improved environment recognition algorithms using some type of sensors like LiDAR and cameras. Additionally, integrated control algorithm for an autonomous vehicle is included. The integrated algorithm was based on C++ environment and supported the stability of the whole driving control algorithms. As to the improved vision algorithms, lane tracing and traffic sign recognition were mainly operated with three cameras. There are two algorithms developed for lane tracing, Improved Lane Tracing (ILT) and Histogram Extension (HIX). Two independent algorithms were combined into one algorithm - Enhanced Lane Tracing with Histogram Extension (ELIX). As for the enhanced traffic sign recognition algorithm, integrated Mutual Validation Procedure (MVP) by using three algorithms - Cascade, Reinforced DSIFT SVM and YOLO was developed. Comparing to the results for those, it is convincing that the precision of traffic sign recognition is substantially increased. With the LiDAR sensor, static and dynamic obstacle detection and obstacle avoidance algorithms were focused. Therefore, improved environment recognition algorithms, which are higher accuracy and faster processing speed than ones of the previous algorithms, were proposed. Moreover, by optimizing with integrated control algorithm, the memory issue of irregular system shutdown was prevented. Therefore, the maneuvering stability of the autonomous vehicle in severe environment were enhanced.

In spite of great interest and recent innovation of the legislative system in the Arbitration and other Alternative Dispute Resolution(ADR) system, In Japan there have been only a few case in which International commercial dispute was settled through the Arbitration compared to other countries. However, we can easily expect that foreign arbitral awards which need to be recognized and enforced in Japan will gradually increase and this makes it very important for us to review the Japanese legislative system regarding recognition and enforcement of foreign arbitral awards. In this paper, I focused on the relations between applicable laws(including convention) regarding recognition and enforcement of foreign arbitral awards in Japan and some issues concerning refusal of recognition and enforcement of foreign arbitral awards. Japan is a member state of several multilateral conventions concerning recognition and enforcement of foreign arbitral awards including the New York Convention of 1958 and at least 20 bilateral agreements which include provisions in relate to the recognition and enforcement of arbitral awards. Therefore there are some legal issues about the priority application between multilateral and bilateral agreements in relate to Article 7(1) of the New York Convention. In Japan, as I mentioned in this paper, there are incoherent opinions concerning this issue. To solve it substantially it would seem appropriate to build up concrete and explicit provisions concerning the application of priority between multilateral and bilateral agreements. On the other hand, in relate to the application between the New York Convention and National Law, it is necessary to take general approach regarding the priority application between Convention (Treaty) and National Law, considering the national application of conventions under the Constitutional System of each country. Among the grounds for non-recognition/enforcement, there are the ones that are decided under the law of the requested country, for instance, arbitrability and public policy. It would therefore be possible that some foreign arbitral awards would not be recognized in Japan especially relating to the arbitrability because its scope in Japan is not so large. Regarding the enforcement of awards annulled in their place of origin, some positive opinions in recent Japanese legal discussions, say that annulled awards should be enforced as a counter strategy of developed countries and judiciary discretion of the requested country would be needed. As mentioned in this paper, the recognition and enforcement of foreign arbitral awards is closely related to judicial policy of the requested country as the recognition and enforcement of foreign judgment is. Even though there existed uniform rules on recognition and enforcement of foreign arbitral awards like the New York convention, each country has different internal legal status of conventions under its own Constitutional System and tends to interpret the provisions based in its own profit. Therefore, it is necessary to review, in the light of conflict of laws, the national legislative system including legal status of conventions of the requested countries concerning recognition and enforcement of foreign arbitral awards.
