A Photomosaic Image Generation on Smartphone

摘要

As the usage of mobile device, such as smartphone is becoming common, persons' interests in user created contents (UCC) are increasing gradually. Especially, the mobile devices combined with camera make that anyone can create UCC easily. In this paper, we introduce the implementation of smartphone application for converting an image which is taken by the phone into a non-photorealistic photomosaic image. Generally, photomosaic requires large database in order to create high quality result. Because the resource of mobile device is restricted, it is hard to store the large database of photomosaic in mobile device. We obtained the effect which increases the database by using the database which consists of rotatable images. We also offer a solution for the performance issue of best match search.
