Big data is widely used in customer relationship management, relationship marketing, financial business improvement, credit information and risk management. Moreover, as non-face-to-face financial transactions have become more active recently due to the COVID-19 virus, the use of financial big data is more demanded in terms of relationships with customers. In terms of customer relationship, financial big data has arrived at a time that requires an emotional rather than a technical approach. In relational marketing, it was necessary to emphasize the emotional aspect rather than the cognitive, rational, and rational aspects. Existing traditional financial data was collected and utilized through text-type customer transaction data, corporate financial information, and questionnaires. In this study, the customer's emotional image data, that is, atypical data based on the customer's cultural and leisure activities, is acquired through SNS and the customer's activity image is analyzed with an artificial intelligence CNN algorithm. Activity analysis is again applied to the annotated AI, and the AI big data model is designed to analyze the behavior model shown in the annotation.

This study utilizes structural equation modeling process to identify contributing factors that have been extracted through the first study of exploring library service and image building related factors. This study, specifically, tests the relationships between endogenous and exogenous variables that are assumed to have inherent relationships when building public library service image. As denoted from the first study, this one uses three dimensions and nine conceptual level constructs and 20 different measurement items for further test. The results of this study is that particular items to measure the image for the users would not have been fitted to the other set of samples. Also, there are differences between the two employee groups in the recognitions of images.

Animation creates meaning and affection by combinig image and sound like film. directed by Yuri Norstein is a good text for analyzing animation sound in that it combines image and various music and sound effects well. This study focuses on analyzing the way that sound function to make meaning in this text. Generally sound is categorized into dialogue, music, and sound effect. And animation has its own characteristic in each category. The voice for dialogue is created corresponding to the image of the character and the rhythm is very important in Animation. Plus Sound effect in animation can be said to mimic not just sound but also movement. This study analyzes sound based on three sound factors and the concepts of the point of listening, subjective sound, and sound bridge. Subjective sound using the point of listening of the wolf and the baby bestows a special position on the main characters in the text. It is the overall characteristic of the sound use of this text that the repetitive combination of sound and image, the linguistic and annotative function of sound effect, and comparatively conventional use of music and sound effect enhance the affection and readability.

This paper proposes database generation and management system for small-pixelized airborne target recognition. The proposed system has five main features: 1) image extraction from in-flight test video frames, 2) automatic image archiving, 3) image data labeling and Meta data annotation, 4) virtual image data generation based on color channel convert conversion and seamless cloning and 5) HOG/LBP-based tiny-pixelized target augmented image data. The proposed framework is Python-based PyQt5 and has an interface that includes OpenCV. Using video files collected from flight tests, an image dataset for airborne target recognition on generates by using the proposed system and system input.

오늘날 인터넷을 통한 정보검색이 일상화되면서 생활상식에서부터 기존에 서적이나 논문 등을 통해서만 알 수 있었던 전문지식까지도 손쉽게 찾을 수 있게 되었다. 즉, 현대생활에 있어서 검색엔진은 원하는 정보를 빠르고 정확하게 찾을 수 있게 해준다는 점에서 매우 중요하다고 할 수 있다. 하지만 이러한 중요성에도 불구하고 검색엔진 기술적인 연구이외에는 서비스 품질이나 고객만족에 대한 연구는 활발하게 이루어지지 않고 있다. 따라서, 본 연구에서는 검색엔진 서비스에 있어서 서비스 품질과 서비스가치, 고객만족, 충성의도의 관계를 연구모형으로 설정하고 이들간의 관계를 분석하였다. 그 결과 서비스품질의 정확성, 정보함유량, 사이트 이미지, 편리성이 서비스가치에 정(+)의 영향을 미치는 것으로 나타났으며, 그중에서 정확성, 사이트 이미지, 신뢰성은 고객만족에도 정(+)의 영향을 미치는 것으로 나타났다. 또한 서비스가치가 높을수록 고객만족은 상당히 높아지는 것으로 나타났으며 고객만족이 충성의도에 많은 영향을 주는 것으로 나타났다. 본 연구의 결론은 검색엔진 서비스 기업이 경쟁우위를 유지하기 위해서는 서비스가치의 구현을 통한 지속적인 고객만족을 달성해야 하며, 이를 위해 정확성, 정보함유량, 편리성, 사이트 이미지에 중점을 둔 고품질 서비스 전략의 필요성을 시사하고 있다.

The system implemented in this paper partitions and stores specimen data captured by a light microscope on distributed or parallel systems. Users ran observe images on computers as we use a physical microscope. Based on the client-server computing model, the system consists of client, coordinator, and data manager. Three components communicate messages. For retrieving images, we implemented the client program with necessary functions for educational applications such at image mark and text annotation, and defined the communication protocol. We performed the experiment for introducing a tape storage which stores a large volume of data. The experiment results showed performance improvement by data partitioning and indexing technique.

During recent years, a new framework, which aims to bring a unified and global approach in indexing, browsing and querying various digital multimedia data such as audio, video and image has been developed. This new system partitions each media stream into smaller units based on actual physical events. These physical events within oath media stream can then be effectively indexed for retrieval. In this paper, we present a new approach that exploits audio, image and video features to segment and analyze the audio-visual data. Integration of audio and visual analysis can overcome the weakness of previous approach that was based on the image or video analysis only. We Implement a web-based multi media data retrieval system called XCRAB and report on its experiment result.

Recently, explosive popularity of multimedia information has triggered the need for retrieving multimedia contents efficiently from the database including audio, video and images. In this paper, we propose an XML-based retrieval scheme and a data model that complement the weak aspects of annotation and conent based retrieval methods. The Property and hierarchy structure of image and video data are represented and manipulated based on the Multimedia Description Schema (MDS) that conforms to the MPEG-7 standard. For audio contents, pitch contours extracted from their acoustic features are converted into UDR string. Especially, to improve the retrieval performance, user's access pattern and frequency are utilized in the construction of an index. We have implemented a prototype system and evaluated its performance through various experiments.

This study attempts to address the problem of 3D pose estimation for multiple human objects through a single image generated during the character development process that can be used in augmented reality. In the existing top-down method, all objects in the image are first detected, and then each is reconstructed independently. The problem is that inconsistent results may occur due to overlap or depth order mismatch between the reconstructed objects. The goal of this study is to solve these problems and develop a single network that provides consistent 3D reconstruction of all humans in a scene. Integrating a human body model based on the SMPL parametric system into a top-down framework became an important choice. Through this, two types of collision loss based on distance field and loss that considers depth order were introduced. The first loss prevents overlap between reconstructed people, and the second loss adjusts the depth ordering of people to render occlusion inference and annotated instance segmentation consistently. This method allows depth information to be provided to the network without explicit 3D annotation of the image. Experimental results show that this study's methodology performs better than existing methods on standard 3D pose benchmarks, and the proposed losses enable more consistent reconstruction from natural images.

최근 멀티미디어의 이용과 멀티미디어 접근을 위한 기술이 많이 증가하고 있다. 그렇지만 멀티미디어 검색엔진과 같은 실용시스템에서 멀티미디어에 대한 유용한 정보 추출과 정보의 응용은 여전히 문제로 있다. 특히, 멀티미디어 이용자는 검색의 효율성을 위하여 저장소를 직관적인 구조로 생성을 하고 있다. 그 예로 "KISS 추계학술 대회 이미지"와 같은 데이터 폴더를 만들거나, 각 멀티미디어 데이터에 Free Text 기반의 주석을 하여 관리를 하였다. 하지만 이러한 검색들에도 한계점을 가지고 있으며 또 다른 지능적인 의미 검색에 있어서도 인간이 바라는 검색의 정확도에 미치지 못하고 있다. 본 논문에서는 이러한 문제점을 해결하기 위한 새로운 접근법을 소개한다. 목적을 위하여 멀티미디어의 의미적인 작업을 위하여 컨텐츠 획득과 분류를 위한 새로운 사용자 도구를 소개하고자 한다. 도구를 이용하는 멀티미디어 사용자는 주어진 컨텐츠를 인간이 생각하고 컨텐츠가 내포하는 의미의 일정한 구조적 단위로 분해하고, 각 단위들에 MPEG-7 표준기반의 추가적인 기술 정보(Description information)를 부여하여 새로운 의미적 메타데이터를 생성할 수 있다. 이러한 의미적 메타데이터는 멀티미디어 검색을 위해 사용자들에게 효율성을 줄 것이라 본다.
