Animated Photomosaics

A photomosaic is an image that is divided into a grid of rectangular cells, each of which is replaced with another image that resembles the cell section of the input image. Animated photomosaics extend the previous technique of photomosaics to resemble a video instead of an image. Limited research exists on animated photomosaics and the existing techniques focus more on real-time processing rather than visual quality. In the thesis, we combine previous work and new techniques to create consistent and smooth animated photomosaics with a focus on visual quality. The main contributions of the thesis project are, (I) a novel method to create photomosaics and animated photomosaics without any image adjustments, (II) a scale based image descriptor suitable for photomosaic applications, and (III) methods to get consistent image matching and maintain the coherence of the animated photomosaic. We show that by extending the general photomosaic method with two temporal extensions, we create a method capable of producing consistent and coherent animated photomosaics.
