본 논문에서는 기존의 특징점 기반 객체 인식 방법의 확장으로 보완적 특징점 기반의 컬러 정보를 포함하는 기술자를 활용하는 객체 인식 방법을 제안한다. 제안하는 방법은 무늬가 적은 객체에서도 에지의 위치를 샘플링함으로써 보완적 특징점을 생성해 낸다. 그리고 검출된 보완적 특징점으로부터 얻어지는 그레이 값 변화도방향 정보와 컬러 정보를 가지고 있는 기술자를 생성한다. 그리고 생성된 기술자를 객체 단위로 묶어 낼 수 있도록 하는 코드북(Codebook)을 학습함으로써 각 객체를 구분해 낼 수 있는 강건한 히스토그램를 생성한다. 생성된 코드북을 활용함으로써 제안하는 방법은 객체의 크기 및 환경 변화, 3차원 회전의 경우에도 기존의 방법보다 강건하게 인식한다. 실험 결과 제안하는 방법은 75.8% 인식률을 보이는 것을 확인하였다. 이 방법은 증강현실 응용에 정보 제시를 위해 가장 먼저 이루어지는 핵심 기술로써 활용될 수 있다.

Galaxy clusters contain a diffuse component of stars outside galaxies, that is observed as intracluster light (ICL). Since the ICL abundance increases during various dynamical exchanges of galaxies, the amount of ICL can act as a measurement tool for the dynamical stage of galaxy clusters. There are two prominent ICL formation scenarios; one is related to the brightest cluster galaxy (BCG) major mergers, and the other to the tidal stripping of galaxies. However, it is still under debate as to which is the main ICL formation mechanism. In this study we improve on earlier observational constraints of the ICL origin, by investigating it in a massive fossil cluster at z~0.47. Fossil clusters are believed to be dynamically matured galaxy clusters which have dominant BCGs. Recent simulation studies imply that, BCGs have assembled 85~90% of their mass by z~0.4 (e.g., Contini et al. 2014). Thus our target is an optimal test bed to examine the BCG-related scenario. Our deep images and Multi-Object Spectroscopic observations of the target fossil cluster (Gemini North 2018A) allow us to extract the ICL distribution, ICL color map and ICL fraction to cluster light. We will present a possible constraint of the ICL origin and discuss its connection to the BCG and the host galaxy cluster.

In this paper, we used a deep learning model to detect and segment flame and smoke in real time from fires. To this end, well known U-NET was used to separate and divide the flame and smoke of the fire using multi-class. As a result of learning using the proposed technique, the values of loss error and accuracy are very good at 0.0486 and 0.97996, respectively. The IOU value used in object detection is also very good at 0.849. As a result of predicting fire images that were not used for learning using the learned model, the flame and smoke of fire are well detected and segmented, and smoke color were well distinguished. Proposed method can be used to build fire prediction and detection system.

The purpose of this study was to analyze the types of aesthetic characteristics and their expression methods in the goth style expressed with the sensibility of an illustrator, using the work of Toon Hertz as an example. As a research method for this purpose, previous studies and books were used to examine the components of fashion illustration, the concept and aesthetic characteristics of goth style, and the world of Toon Hertz's work. In the qualitative studies, Toon Hertz's works were collected and the characteristics of each component were analyzed. As a result of analyzing the aesthetic characteristics, Distortion appeared as the main element of the human body, and the human body was distorted through the method of combining the human body with animals, plants, and other objects. History was mainly expressed through fashion elements. Victorian clothing was predominant, the color was mainly black, and it was characterized by decorations, such as fancy laces, corsets, and shirrings. The screen layout and the object components appeared as the main components of mystery. Sensuality was a major component of the human body, and it emphasized decadent and sensual images of a woman sitting with both legs apart or placing her hands on her legs or chest. Fear was the main component of the human body, and strangeness and fear were created by omitting or removing parts of the body, such as women's arms, legs, hands, or eyes.

A blind box is a kind of sales method in that you can only get the product information by opening the package. In 2019, blind box products began to grow rapidly in the Chinese market, and gradually formed a special "blind box economy". The particularity of blind box products is that driven by consumers' curiosity, consumers' purchasing behavior can be directly induced by the visual and tactile perception of commodity packaging. Therefore, it is necessary to explore the psychological needs of consumers and master the blind box packaging design elements under the influence of consumer psychology. This paper takes figurine blind box packaging elements as the research scope and Chinese blind box consumers as the research object. Through market research and literature study, We are designed to conduct a questionnaire survey and SPSS empirical study to find out the differences in the preferences of different consumer temperament types for blind box packaging, taking the characteristics of blind box products and consumer psychology as the relevant theoretical background. The research results show that among the blind box consumers, choleric type consumers predominate, the color of the blind box packaging presents red, orange, and yellow preference, and the material presents metal, and plastic preference. The shape of the blind box shows a preference for special shape.

In this study, we propose a multi-GPU-based 8KVR stitching system that operates in real time on both local and cloud machine environments. The proposed system first obtains multiple 4 K video inputs, decodes them, and generates a stitched 8KVR video stream in real time. The generated 8KVR video stream can be downloaded and rendered omnidirectionally in player apps on smartphones, tablets, and head-mounted displays. To speed up processing, we adopt group-of-pictures-based distributed decoding/encoding and buffering with the NV12 format, along with multi-GPU-based parallel processing. Furthermore, we develop several algorithms such as equirectangular projection-based color correction, real-time CG overlay, and object motion-based seam estimation and correction, to improve the stitching quality. From experiments in both local and cloud machine environments, we confirm the feasibility of the proposed 8KVR stitching system with stitching speed of up to 83.7 fps for six-channel and 62.7 fps for eight-channel inputs. In addition, in an 8KVR live streaming test on the 5G MEC/cloud, the proposed system achieves stable performances with 8 K@30 fps in both indoor and outdoor environments, even during motion.

We present the results of long-term simultaneous monitoring observations (~ 12 years) of H²O (22 GHz) maser and several vibrationally excited lines of SiO J = 1-0, 2-1, 3-2 masers (43, 86, 129 GHz) carried out with the 21-m antennas of the Korean VLBI Network (KVN) toward a sample of three AGB stars (RT Vir, RR Aql, IRC-10151) that are believed to be semiregular variable star, Mira variable star, and OH/IR star, respectively, according to a sequential evolutionary phase of AGB star. A total 10 transitions were observed, of which we detected H²O, SiO 𝝊 = 1 and 2, J = 1-0, SiO 𝝊 = 1, J = 2-1 and J = 3-2 maser lines in all three target objects, depending on the observational epochs. In this study, we scrutinize the evolutionary traits of each target object based on the maser line profiles, flux/velocity variations, and phase lags with the optical light curves. The IRAS two color diagram and the infrared spectral energy distributions (SEDs) in the wavelength range from 1.2 to 240 ㎛ of three observed sources were also analyzed.

We report the optical follow-up observations of three long γ-ray burst events, GRB 201020A, GRB 201103B and GRB 210104A by the network of telescopes in the SomangNet project. We show light curves, color evolution and SED evolution, and fit them to a single power law function to derive decay index and compare their properties with other long GRBs samples. Also, we show a good observational example that 0.4-1m class telescopes in SomangNet have potential to catch dim light from high red shift object (R>22 mag) by deep imaging. In conclusion, we found that three GRBs have optical afterglow properties of long GRB and our results are consistent with the reports of high energy analysis.

This study has been carried out with the object of researching into the situation of the genetic isolation of a Korean population located near Seoul. The results obtained are summarized as follows: In general, the distribution of P.T.C. threshold values in the population is close to that of the Seoul population. But the nonataster frequency of male in the population is higher than that of female, and this is in agreement with the status of ankyloglossia frequency in male. However the relationship between the two traits has not been clarified. The gene frequencies of rolling and folding of tongue are slightly lower than that of the Seoul population. The gene frequency conditioning the ability to twist the tongue is lower in the male than in the female. The color-blindness is 6.21 percent, and it is slightly higher than that of other Korean population. All considered, the studied population might be regarded to have been kept in genetic isolation.
