Photo collage-based photograph display system on mobile computing platform

Abstract

In the last few decades, mobile computing platform technology has grown rapidly, as observed from smart phones that have quickly become ubiquitous. The mobile computing platform is the most widely used platform in our life today, and digital photographs captured through these devices have become routine for most people. In this study, we propose a novel artistic method for displaying photographs in mobile devices as a photo collage. Using our system, users can view a representative photograph as a collage of photographs associated with a certain event, and access each of photographs individually. To implement this, we employ centroidal Voronoi diagram (CVD) to obtain an even distribution of tiles, and use the sites as the location of tiles. We use the edge avoidance technique to prevent tiles from being located across the edges. To obtain the direction of tiles that follow near a strong edge, we employ the Edge tangent Flow field, and use the field as the directions of tiles. Finally, we search for photos that best match the tiles calculated above by using a thumbnail difference metric.

Painting-Emotion Matching Technology Learning System through Repetition

“…In addition, non-realistic rendering technologies using programs are developing. Rendering systems can also be improved if learning increases the ability to find emotion from paintings [3][4][5][6]. Therefore, this study aims to improve the ability of users to understand paintings by providing them with learning tools that help them to analyze the emotions of a given painting.…”
