  • This study introduces artificial intelligence (AI) techniques for video generation. For an effective illustration, techniques for video generation are classified as either semi-automatic or automatic. First, we discuss some recent achievements in semi-automatic video generation, and explain which types of AI techniques can be applied to produce films and improve film quality. Additionally, we provide an example of video content that has been generated by using AI techniques. Then, two automatic video-generation techniques are introduced with technical details. As there is currently no feasible automatic video-generation technique that can generate commercial videos, in this study, we explain their technical details, and suggest the future direction for researchers. Finally, we discuss several considerations for more practical automatic video-generation techniques.

  • 대화 모델은 대표적으로 검색 모델 또는 생성 모델을 기반으로 구현된다. 최근에는 두 모델의 장점은 융합하고 단점은 보완하기 위해 검색 기법과 생성 기법을 결합하는 연구가 활발히 이루어지고 있다. 그러나 생성 모델이 검색된 응답을 전혀 반영하지 않고 응답을 생성하여 검색 모델을 간과하는 문제 또는 검색된 응답을 그대로 복사해 생성하여 검색 모델에 과의존하는 문제가 발생한다. 본 논문에서는 이러한 문제들을 완화하며 검색 모델과 생성 모델을 모두 조화롭게 활용할 수 있는 대화 모델을 제안한다. 생성 모델이 검색 모델을 간과하는 문제를 완화하기 위해 학습 시 골드 응답을 검색된 응답과 함께 사용한다. 또한, 검색 모델에 과의존하는 문제를 완화하기 위해 검색된 응답들의 내용어 일부를 마스킹하고 순서를 무작위로 섞어 노이징한다. 검색된 응답은 대화 컨텍스트와의 관련성이 높은 것만을 선별하여 생성에 활용한다. 정량 평가 및 정성 평가를 통해 제안한 방법의 성능 향상 효과를 확인하였다.

  • Purpose Generative Adversarial Network(GAN) is one of deep learning technologies. This is a way to create a real fake image after learning the real image. In this study, after acquiring artificial intelligence images through GAN, We were compared and evaluated with real scan time images. We want to see if these technologies are potentially useful. Materials and Methods 30 patients who underwent 18F-FDG Brain PET/CT scanning at Severance Hospital, were acquired in 15-minute List mode and reconstructed into 1,2,3,4,5 and 15minute images, respectively. 25 out of 30 patients were used as learning images for learning of GAN and 5 patients used as verification images for confirming the learning model. The program was implemented using the Python and Tensorflow frameworks. After learning using the Pix2Pix model of GAN technology, this learning model generated artificial intelligence images. The artificial intelligence image generated in this way were evaluated as Mean Square Error(MSE), Peak Signal to Noise Ratio(PSNR), and Structural Similarity Index(SSIM) with real scan time image. Results The trained model was evaluated with the verification image. As a result, The 15-minute image created by the 5-minute image rather than 1-minute after the start of the scan showed a smaller MSE, and the PSNR and SSIM increased. Conclusion Through this study, it was confirmed that AI imaging technology is applicable. In the future, if these artificial intelligence imaging technologies are applied to nuclear medicine imaging, it will be possible to acquire images even with a short scan time, which can be expected to reduce artifacts caused by patient movement and increase the efficiency of the scanning room.

  • The Stable diffsuion AI tool is popular among designers because of its flexible and powerful image generation capabilities. However, due to the diversity of its AI models, it needs to spend a lot of time testing different AI models in the face of different design plans, so choosing a suitable general AI model has become a big problem at present. In this paper, by comparing the AI images generated by two different Stable diffsuion models, the advantages and disadvantages of each model are analyzed from the aspects of the matching degree of the AI image and the prompt, the color composition and light composition of the image, and the general AI model that the generated AI image has an aesthetic sense is analyzed, and the designer does not need to take cumbersome steps. A satisfactory AI image can be obtained. The results show that Playground V2.5 model can be used as a general AI model, which has both aesthetic and design sense in various style design requirements. As a result, content designers can focus more on creative content development, and expect more groundbreaking technologies to merge generative AI with content design.
