This review aims to provide a brief, comprehensive overview of advanced technologies of nuclear medicine physics, with a focus on recent developments from both hardware and software perspectives. Developments in image acquisition/reconstruction, especially the time-of-flight and point spread function, have potential advantages in the image signal-to-noise ratio and spatial resolution. Modern detector materials and devices (including lutetium oxyorthosilicate, cadmium zinc tellurium, and silicon photomultiplier) as well as modern nuclear medicine imaging systems (including positron emission tomography [PET]/computerized tomography [CT], whole-body PET, PET/magnetic resonance [MR], and digital PET) enable not only high-quality digital image acquisition, but also subsequent image processing, including image reconstruction and post-reconstruction methods. Moreover, theranostics in nuclear medicine extend the usefulness of nuclear medicine physics far more than quantitative image-based diagnosis, playing a key role in personalized/precision medicine by raising the importance of internal radiation dosimetry in nuclear medicine. Now that deep-learning-based image processing can be incorporated in nuclear medicine image acquisition/processing, the aforementioned fields of nuclear medicine physics face the new era of Industry 4.0. Ongoing technological developments in nuclear medicine physics are leading to enhanced image quality and decreased radiation exposure as well as quantitative and personalized healthcare.

This study aims to explore the Internet personal broadcasting quality factors that influence viewer satisfaction and dissatisfaction based on the motivation-hygiene theory. Specifically, the quality factors that affect viewer satisfaction of Internet personal broadcasting are derived from the perspectives of extrinsic (contents usefulness and media usability), intrinsic (emotional/cognitive/behavioral enjoyment and creator characteristics), and social motivation (visibility, subjective norm, image, sociality). The data of 200 respondents was used to analyze the relative impact of satisfaction and dissatisfaction with the Kano model, which assumes that viewer satisfaction at both functional and emotional levels varies over quality attributes. In the empirical analysis, the quality factors were classified into attractive, one-dimensional, must-be, and indifferent quality. In addition, it was found that the customer satisfaction coefficient was high in the order of uniqueness, differentiation, and visibility. On the other hand, as a result of applying the dissatisfaction coefficient, it was identified in the order of donation, content reliability, and creator responsiveness.

The purpose of this study is to investigate the teacher-students interactions shown in the images of elementary science class by preservice teachers. We applied nine analysis criteria in three domains such as emotional support (climate, regard for student perspectives, teacher sensitivity), classroom organization (instructional learning formats, behavior management, productivity), and instructional support (quality of feedback, language modeling, concept development) in the aspects of positive or negative interactions The results show that majority of student-teachers tended to prefer positive interactions especially regarding instructional learning formats or concept development. For the image of avoided class, they tended to show negative interactions related to instructional learning formats or regard for student perspectives. However, they showed extremely lower frequencies for some categories of negative interactions. Female preservice teachers tended to have slightly higher frequencies for some positive interactions than their counterpart. The findings indicate possible approaches to teachers' professional development and further research.

This Study is about the color images oi clothes in the early 20th century in the Eastern and Western culture and the recreation of this color images through modern costume design in film. The aim of this study is to show how early 20th century color has born reinterpreted through present film costumes and how different cultural perspectives can influence color images. For the purposes of this study, 30 pictures of clothing, representative of the early 20th century, as well as films which have been internationally recognized for their costume design and strong cultural identity('Farewell M) 'Concubine', 'Raise the Red Lantern', 'Chicago' and 'The English Patient') were chosen and analyzed. The color image of these photographs and scenes from the movies were divided by Pantone Solid Chips and categorized by color groups such as red, orange, yellow, green, blue, violet, neutral and metallic. The analysis results of the color images in the early 20th century showed that the red group was used a lot in both cultures and the orange group was more often used in the West. In regards to the yellow group, goldish yellow were commonly used in the West but pale yellow was preferred in the East. The green group more used In the West but the blue group appears more in the East. Also, there were differences in color combination, texture and technique which demonstrates different cultural color recognition and association. In the case of film color image, present color image was added to past color image. In the West, color was used as a tool for visualizing the state of characters' mind and the mood of movies' story but in the East color image was intended to make the character stand out by changing the value and chroma. By comparing the color image of clothes from the early 20th century and color image from film in the West and the East, it is possible to analyze the cultural symbolic image of color. This study is one of first trials to analyze the cultural differences in rotor images and their symbolic meaning. Thus, further studies should persue to find out the influence of culture on the rotor image in terms of specific quantity and quality.

Uneven light in real-world causes visual degradation for underexposed regions. For these regions, insufficient consideration during enhancement procedure will result in over-/under-exposure, loss of details and color distortion. Confronting such challenges, an unsupervised low-light image enhancement network is proposed in this paper based on the guidance of the unpaired low-/normal-light images. The key components in our network include super-resolution module (SRM), a GAN-based low-light image enhancement network (LLIEN), and denoising-scaling module (DSM). The SRM improves the resolution of the low-light input images before illumination enhancement. Such design philosophy improves the effectiveness of texture details preservation by operating in high-resolution space. Subsequently, local lightness attention module in LLIEN effectively distinguishes unevenly illuminated areas and puts emphasis on low-light areas, ensuring the spatial consistency of illumination for locally underexposed images. Then, multiple discriminators, i.e., global discriminator, local region discriminator, and color discriminator performs assessment from different perspectives to avoid over-/under-exposure and color distortion, which guides the network to generate images that in line with human aesthetic perception. Finally, the DSM performs noise removal and obtains high-quality enhanced images. Both qualitative and quantitative experiments demonstrate that our approach achieves favorable results, which indicates its superior capacity on illumination and texture details restoration.

This paper proposes a method to calibrate a thermal camera with three different perspectives. In particular, the intrinsic parameters of the camera and re-projection errors were provided to quantify the accuracy of the calibration result. Three lenses of the camera capture the same image, but they are not overlapped, and the image resolution is worse than the one captured by the RGB camera. In computer vision, camera calibration is one of the most important and fundamental tasks to calculate the distance between camera (s) and a target object or the three-dimensional (3D) coordinates of a point in a 3D object. Once calibration is complete, the intrinsic and the extrinsic parameters of the camera(s) are provided. The intrinsic parameters are composed of the focal length, skewness factor, and principal points, and the extrinsic parameters are composed of the relative rotation and translation of the camera(s). This study estimated the intrinsic parameters of thermal cameras that have three lenses of different perspectives. In particular, image enhancement based on a deep learning algorithm was carried out to improve the quality of the calibration results. Experimental results are provided to substantiate the proposed method.
