We then propose a pragmatic method that implements the framework using the “image-as-a-document” approach.","PeriodicalId":318936,"journal":{"name":"Int. J.

Therefore, it is important to determine how to adequately improve CS. Consumers’ responses to questionnaires are generally used to evaluate CS. A simple method of identifying improvement factors for CS is to select those factors with high dissatisfaction scores at a given point of time. However, these factors change rapidly, especially in the information and communication technology (ICT) field, due to the rapid technological developments, competition, and the business environment. Thus, companies should adequately capture customers’ changes in perception of their ICT services.","PeriodicalId":318936,"journal":{"name":"Int. J.

Unlike ordinary document retrieval, API member sets obtained by mining are often similar to each other and are mixtures of several unimportant and/or irrelevant elements. Thus, an API member set search tool needs to have the ability to extract an essential part of each API member set and to be equipped with an efficient searching interface. We propose a method to improve the searchability of API member sets by utilizing inclusion graphs among API member sets that are automatically extracted from source code. The proposed method incorporates the frequent pattern mining to obtain inclusion graphs and offers the user a way to search appropriate API member sets smoothly and intuitively by using a GUI. In this paper, we describe the details of our method and the design and implementation of the prototype and discuss the usability of the proposed tool.","PeriodicalId":318936,"journal":{"name":"Int.

{"title":"Do You Like Sclera? Sclera-region Detection and Colorization for Anime Character Line Drawings","authors":"M. Aizawa, Y. Sei, Yasuyuki Tahara, R. Orihara, Akihiko Ohsuga","doi":"10.2991/IJNDC.K.190711.001","DOIUrl":"https://doi.org/10.2991/IJNDC.K.190711.001","url":null,"abstract":"Line drawing colorization is an important process in creating artwork such as animation, illustrations and color manga. Many artists color work manually, a process that requires considerable time and effort. In addition, colorizing requires special skills, experience, and knowledge, and this makes such work difficult for beginners. As a result, automated line drawing colorizing methods have significant market demand. However, it is difficult to paint artistic works. Many automated colorizing methods have been developed, but several problems arise in art colorized using these methods. For example, colors may be different in a region that should be painted the same color as another region, or a mismatch may occur between the input line drawing and the colorizing result due to difficulty in understanding the sketches, the inclusion of undesirable artifacts, and other issues. Anime character’s eyes are drawn in various styles, depending on the artists’ preferences. In some styles, eyes are overly abstract. In addition, in grayscale line drawings, the skin and sclera are both expressed in white in many cases. Therefore, the boundaries cannot always be determined using existing automated colorizing techniques. As a result, sclera are often painted the same color as the skin, and there is a mismatch between these regions in the line drawing and the colorizing results. Facial features are important in artworks that depict people, and excessive ambiguity at the boundary between the eyes and the skin may impair quality. Therefore, it is expected that sclera-region detection should improve the accuracy of automated colorizing of grayscale line drawings of people. This paper focuses on inconsistencies in the sclera region between line drawings and colorizing results; we aim to match the structure of line drawings and colorizing results by detecting the sclera regions in grayscale line drawings of people to improve the accuracy of automated colorizing (Figure 1). In our proposed framework, we perform machine learning using a pair of line drawings and a mask image. The sclera regions are labeled to create semantic segmentation models of the sclera regions. Then, to colorize the line drawing, the semantic segmentation models detect the sclera regions, and we apply these regions to the automated colorizing result. As a result, our framework maintains the correct sclera-region color. When using the semantic segmentation model, it is possible to detect sclera regions without requiring the user to add hints. In this paper, we propose two mask image creation methods: the manual type and the graph cut type. Compared with the manual type, the graph cut type can reduce the mask image creator’s burden.","PeriodicalId":318936,"journal":{"name":"Int. J.

Each computer connected to the network in the system acts as a node, receiving a copy of the blockchain and functioning as an “administrator” on the network, continually verifying data and ensuring security within the platform. The fundamental principle behind this technology is that the distributed network it operates on minimizes the risk of a single vulnerability point characteristic of a centralized database. While seemingly infallible, this technology has still been subject to exploitation by financially motivated attackers. The most famous instance, known as the DAO bug, occurred when an attacker utilized a “re-entrancy” vulnerability within an Ethereum smart contract that succeeded in stealing 60 million US$ [2]. For our research, we have decided to focus our attention on the Ethereum blockchain, presently the second most popular cryptocurrency with a current market valuation of roughly 13 billion US$ [3].","PeriodicalId":318936,"journal":{"name":"Int.

In addition, captioning can assist with understanding content. Understanding of content can be deepened in a short time by reading captions. Among captioning models that use deep training, the encoder–decoder [1] model has generated considerable results and attracted attention, but many existing studies only consider the consistency of contiguous scenes over short periods. Considering the consistency of video segments as a matter of captioning has high importance. Generating cooking recipe sentences from cooking videos can be considered a captioning problem by treating recipes as captions. In addition, because the cooking video is constituted as a set of fragmentary tasks, a model that considers the consistency of the whole video is considered to be effective.","PeriodicalId":318936,"journal":{"name":"Int.

This situation highlights the classic information overload problem. In battlefield situations, the issue of deciding which information is most relevant is critical to mission success.
