  • Images are 2-dimensional projection of 3-dimensional scenes and many problems of scene analysis arise due to inherent depth ambiguities in a monocular 2-D image. Therefore, depth recovery is a crucial problem in image understanding. This paper proposes modified algorithm which is focused on accurate correspondnce in stereo vision. The feature we use is zero-crossing points and the similarity measure with two property evaluation function is used to estimate initial probability. And we introduce relaxation technique for accurate and global correspondence.

  • This study is on the production and the classification of a new appreciation methods of seascape through materials in the words of Korean popular songs. In advance, it is necessary to understand the popular songs as collective representation and the songs are analytic data. In this study, some essential elements of seascape in popular songs are analyzed and classified. They are; 1. visible elements-weather, time, season and object. 2. all senses-vision, audition, olfaction, tactile sense, and spatial sense. 3. the line of vision-static line of vision and dynamic line of vision. In this way data is produced, and then the result of this study makes appreciation methods of seascape developed. In this way, this study results in developed appreciation of seascape. This study on new understanding of appreciation methods of seascape is on the basis of a design method of water-front that is considered a visible scene, not a design of construction elements.

  • Surface dry condition examination method on the KS F 2504(Testing method for specific gravity and absorption of fine aggregate) has dim detail prescriptions which can cause different ways of understanding based on one's convinence, not on correct means of rule. So we investigate the problems about the inconsistency on decisioing surface dry condition at management examination in the lab and scene. In conclusion, free-falling method is easier and faster than self-weight method. And we also found that the most important face on decisioning surface dry is compacting factor of tamping rod.

  • Object detection is a fundamental task for many high-level computer vision applications such as image retrieval, scene understanding, activity recognition, visual surveillance and many others. Although object detection is one of the most popular problems in computer vision and various algorithms have been proposed thus far, it is also notoriously difficult, mainly due to lack of proper models for object representation, that handle large variations of object structure and appearance. In this article, we review a branch of object detection algorithms based on Support Vector Machines (SVMs), a well-known max-margin technique to minimize classification error. We introduce a few variations of SVMs-Structural SVMs and Latent SVMs-and discuss their applications to object detection and localization.

  • 재난상황이 발생했을 때 피해를 줄이고 신속한 인명구조를 위해서 골든타임을 지키는 것이 중요하다. 그러나 현장까지의 이동이나 현장에서의 진입 경로 확보에 어려움을 겪어 골든타임을 지키지 못해 재난사고의 피해가 커지는 일이 발생하는 경우가 있다. 소방대원들이 현장에 도착하기 전 재난현장에 대한 사전 파악이 이루어지기 힘들기 때문이다. 이러한 문제를 해결하기 위해 재난용 드론을 사용하여 현장에 소방대원들이 도착하기 전 사전에 재난상황을 확인하여 골든타임을 확보할 수 있다. 본 논문에서 제안하는 신속한 재난현장 상황 파악을 위한 오픈소스 기반의 사물 인식이 가능한 드론 시스템은 지상제어시스템을 통해 드론의 제어와 실시간 영상 확인 및 사물 인식이 가능하다. 또한 재난사고 현장은 통신환경이 제대로 동작하지 않을 가능성이 있기 때문에 이를 고려하여 설계되었다. 제안하는 시스템은 오픈소스 기반 적은 비용으로 효과적인 현장 파악이 가능하다.

  • Object detection is a fundamental yet challenging task in computer vision that plays an important role in object recognition, tracking, scene analysis and understanding. This paper aims to propose a multiproperty fusion algorithm for moving object detection. First, we build a scale-invariant feature transform (SIFT) vector field and analyze vectors in the SIFT vector field to divide vectors in the SIFT vector field into different classes. Second, the distance of each class is calculated by dispersion analysis. Next, the target and contour can be extracted, and then we segment the different images, reversal process and carry on morphological processing, the moving objects can be detected. The experimental results have good stability, accuracy and efficiency.

  • Current two-dimensional (2D) augmented reality (AR) devices present virtual image and information to a fixed focal plane, regardless of the various locations of ambient objects of interest around the observer. This limitation can lead to a visual discomfort caused by misalignments between the view of the ambient object of interest and the visual representation on the AR device due to a failing of the singular fusion. Since the misalignment becomes more severe as the depth difference gets greater, it can hamper visual understanding of the scene, interfering with task performance of the viewer. Thus, we analyzed the range of singular fusion (RSF) of AR images within which viewers can perceive the shape of an object presented on two different depth planes without difficulty due to the failure of singular fusion. It is expected that our analysis can inspire the development of advanced AR systems with low visual discomfort.

  • With Unity creating footage is possible by using 3D motion, 2D motion, particular, and sound. Even post-production video editing is possible by combining the footage. In particular, Cinemachine, a suite of camera tools for Unity, that greatly affects screen layout and the flow of video images, can implement most of the functions of a physical camera. Visual aesthetics can be achieved through it. However, as it is a part of a game engine. Thus, the understanding of the game engine should come first. Also doubts may arise as to how similar it is to a physical camera. Accordingly, the purpose of this study is to examine the advantages and cautions of virtual cameras in Cinemachine, and explore the potential for development by implementing storytelling directly.

  • The novel literature of the Romantic era was characterized by emotionally charged and imaginatively rich works. During this period, authors brought a new flow to the literary scene by exploring romantic themes in their unique styles. Various themes and genres emerged, diversifying the novel's target audience. It was during this era that Emily Brontë's "Wuthering Heights" was published. In this paper, we aim to explore the theme of alleviating internal turmoil within this novel, focusing on one enigmatic character, Heathcliff, among the main protagonists. We will illuminate Heathcliff's tumultuous past, analyzing the intricate connections of events that led to profound psychological anguish. By scrutinizing his actions and outward expressions, this paper seeks to understand the manifestation of his internal pain in interactions with other characters. We present a more comprehensive understanding of "Wuthering Heights," transcending the conventional boundaries of literary analysis. It not only proposes practical methods for alleviating internal turmoil but also sheds light on the timeless theme of divine love, offering readers a profound framework for interpreting the complexities of human relationships and the pursuit of inner peace.

  • 감정은 서사 생성과 이해 모두에서 중요한 역할을 한다. 본 논문은 플루칙의 감정 모델을 기반으로 영화 대본에서 8가지 감정 표현을 분석하였다. 먼저 각 장면별 수동으로 감정을 태깅하였고, 이 때 8가지 감정 중 분노, 공포, 그리고 놀람이 가장 우세하게 나타났는데, 이는 스릴러 영화 장르를 고려할 때 의미있다고 할 수 있다. 또한, 스토리에서 긴장이 가장 고조되는 클라이맥스에서 다양한 감정이 복합적으로 나타난다고 가정하였고, 대본 상에서 3 부분의 클라이맥스를 확인할 수 있었다. 그 다음으로 파이썬 (Python) 프로그래밍 언어 기반 자연어처리 도구인 NLTK (Natural Language ToolKit)의 감성 분석 도구를 이용하여 수동 감정 태깅과 비교한 결과, 분노와 공포 감정에서 높은 일치율을, 그리고 놀람, 기대, 혐오 감정에서는 낮은 일치율을 보임을 확인하였다.
