This study presents a method for capturing photographs of users as input and converting them into 2D character animation sprites using a generative adversarial network-based artificial intelligence network. Traditionally, 2D character animations have been created by manually creating an entire sequence of sprite images, which incurs high development costs. To address this issue, this study proposes a technique that combines motion videos and sample 2D images. In the 2D sprite generation process that uses the proposed technique, a sequence of images is extracted from real-life images captured by the user, and these are combined with character images from within the game. Our research aims to leverage cutting-edge deep learning-based image manipulation techniques, such as the GAN-based motion transfer network (impersonator) and background noise removal (U² -Net), to generate a sequence of animation sprites from a single image. The proposed technique enables the creation of diverse animations and motions just one image. By utilizing these advancements, we focus on enhancing productivity in the game and animation industry through improved efficiency and streamlined production processes. By employing state-of-the-art techniques, our research enables the generation of 2D sprite images with various motions, offering significant potential for boosting productivity and creativity in the industry.

Radiologists and trauma surgeons should monitor for early killers among patients with thoracic trauma, such as tension pneumothorax, tracheobronchial injuries, flail chest, aortic injury, mediastinal hematomas, and severe pulmonary parenchymal injury. With the advent of cutting-edge technology, rapid volumetric computed tomography of the chest has become the most definitive diagnostic tool for establishing or excluding thoracic trauma. With the notion of "time is life" at emergency settings, radiologists must find ways to shorten the turnaround time of reports. One way to interpret chest findings is to use a systemic approach, as advocated in this study. Our interpretation of chest findings for thoracic trauma follows the acronym "ABC-Please" in which "A" stands for abnormal air, "B" stands for abnormal bones, "C" stands for abnormal cardiovascular system, and "P" in "Please" stands for abnormal pulmonary parenchyma and vessels. In the future, utilizing an artificial intelligence software can be an alternative, which can highlight significant findings as "warm zones" on the heatmap and can re-prioritize important examinations at the top of the reading list for radiologists to expedite the final reports.

According to the market research report, the nuclear decommissioning services market is currently experiencing considerable growth, with a projected Compound Annual Growth Rate (CAGR) of nearly 13% during the 2020-2024 forecast period. This expansion is primarily fueled by the advancement of Industry 4.0, in conjunction with the emergence of cutting-edge technologies such as the Internet of Things, big data, artificial intelligence, and 5G. Even though the fact that robots have already been utilized in the nuclear industry, their adoption has been hindered by conservative regulations. However, the nuclear decommissioning market presents an opportunity for the advancement of robotics technology. The British have already invested heavily in encouraging the use of intelligent robots for nuclear decommissioning, and other countries, such as Taiwan, should follow suit. Taiwan's flourishing robotics development industry in manufacturing, logistics, and other domains can be leveraged to introduce advanced robotics in the decommissioning of its nuclear power plants. By doing so, Taiwan can establish itself as a competitive player in the nuclear decommissioning services market for the next two decades.

This study is on modulo scheduling algorithms for multicore processor in machine learning applications. Machine learning algorithms are designed to perform a large amount of operations such as vectors and matrices in order to quickly process large amounts of data stream. To support such large amounts of computations, processor architectures to support applications such as artificial intelligence, neural networks, and machine learning are designed in the form of parallel processing such as multicore. To effectively utilize these multi-core hardware resources, various compiler techniques are being used and studied. In this study, among these compiler techniques, we analyzed the modular scheduler, which is especially important in one core's computation pipeline. This paper looked at and compared the iterative modular scheduler and the swing modular scheduler, which are the most widely used and studied. As a result, both schedulers provided similar performance results, and when measuring register pressure as an indicator, it was confirmed that the swing modulo scheduler provided slightly better performance. In this study, a technique that divides recurrence edge is proposed to improve the minimum initiation interval of the modulo schedulers.

중적외선(mid-wave infrared, MWIR) 영상은 피복 및 객체의 온도를 파악할 수 있어 환경, 국방 등 다양한 분야에서 핵심 데이터로 사용된다. KOMPSAT-3A 위성은 타 위성에 비해 높은 공간해상도의 MWIR 영상을 제공하지만, 광학(electro-optical, EO) 영상에 비해 상대적으로 낮은 시인성을 가져 활용성의 확대에 어려움을 겪는다. 이에 본 연구에서는 KOMPSAT-3A 전정색(panchromatic, PAN) 영상의 윤곽 정보를 기반으로 시인성이 높은 MWIR 융합 영상을 제작하고자 한다. 먼저, 이종 센서에서 취득된 PAN 영상과 MWIR 영상의 상대 기하오차를 제거하는 전처리를 수행하고, 딥러닝 기반 윤곽 정보 추출 기술인 Pixel difference network (PiDiNet)의 사전 학습 모델을 이용하여 PAN 영상에 대한 윤곽 정보를 추출한다. 이후 전처리된 MWIR 영상과 추출된 윤곽 정보를 중첩하여 객체 경계면이 강조된 MWIR 융합 영상을 제작한다. 제안 방법을 이용하여 서로 다른 세 지역에 대한 MWIR 융합 영상을 제작하였으며, 이를 시각적으로 분석하였다. 본 기법을 통해 제작된 MWIR 융합 영상은 지형 및 지물의 경계면이 강조되어 시인성이 개선되었으며, 세부적으로 관심 지역에 대한 열 정보를 전달할 수 있었다. 특히, MWIR 융합 영상에서는 저해상도의 원본 MWIR 영상에서 식별할 수 없었던 비행기, 선박 등의 객체를 육안으로 판독할 수 있었다. 본 연구는 가시적인 정보와 열 정보를 동시에 고려할 수 있는 단일 영상 제작 방법론을 제시하였으며, 이는 MWIR 영상의 활용성 확대에 이바지할 수 있을 것으로 사료된다.
