With the growing use of mobile devices such as smartphones, tablet PCs, and digital cameras, photography has become an integral part of everyday life. In particular, mobile devices with cameras allow us to easily capture and modify photographs that can be shared via social networks. In this paper, we introduce a mobile device application for converting(More)
In mosaic art, tiles of unique color, material, and shape are arranged on a plane to form patterns and shapes. Although previous research has been carried out on creating static mosaic-like images from non-mosaic input, mosaic animation requires a method to maintain the temporal coherence of tiles. Here we introduce a method that creates mosaic animations(More)
Texture transfer is a method that copies the texture of a reference image to a target image. This technique has an advantage in that various styles can be expressed according to the reference image, in a single framework. However, in this technique, it is not easy to control the effect of each style. In addition, when this technique is extended to(More)
According to the growth of mobile technology, people experience high-performance mobile devices. In this environment, processing in real-time is required for mobile application. For colored paper mosaic application on mobile devices, the problem regarding speed must be solved while maintaining high-quality. In this paper, we propose an accelerated method(More)
With the growing use of social networking services, various applications have been developed to utilize their vast capabilities. Photomosaic techniques, which combine many images to create a new rendering of an input image, can benefit from the capabilities of social networks. In this study, we propose a method that generates a photomosaic image by(More)
Computer graphics and image processing technologies for editing photographs taken by a user, and for photographic entertainment, have increased in recent years. One of these techniques, non-photorealistic rendering (NPR), is the focus of this study. In this study, we propose a method for applying David Hockneys photographic collage filtering on mobile(More)
This study presents a real-time texture transfer method for artistic style transfer for video stream. We propose a parallel framework using a T-shaped kernel to enhance the computational performance. With regard to accelerated motion estimation, which is necessarily required for maintaining temporal coherence, we present a method using a downscaled motion(More)
In this paper, we present a smartphone based e-book application with interactive illustration authoring tool. The target readers of our e-book are children who study foreign language. Our application aims to educate preschool age children's foreign language by telling folktales with illustrations. To encourage effective learning, our application provides a(More)
