Abstract


Changing the style of an image/video while preserving its content is a crucial criterion to access a new neural style transfer algorithm. However, it is very challenging to transfer a new map art style to a certain video in which \say{content} comprises a map background and animation objects. In this paper, we present a novel comprehensive system that solves the problems in transferring map art style in such video. Our system takes as input an arbitrary video, a map image, and an off-the-shelf map art image. It then generates an artistic video without damaging the functionality of the map and the consistency in details. To solve this challenge, we propose a novel network, Map Art Video Network (MAViNet), the tailored objective functions, and a rich training set with rich animation contents and different map structures. We have evaluated our method on various challenging cases and many comparisons with those of the related works. Our method substantially outperforms state-of-the-art methods in terms of visual quality and meets the mentioned criteria in this research domain.

Results


Our system generates different MArt styles with different content videos



Brusells style


Chester style


Colorado style


Results on raw content videos, i.e., we hypothesize that the background of the input video is the map and we want to preserve the content structure of the background




Results on single images



Results on single images with natural content, i.e., non-map-background

Our failure results


In the cases that the map art styles compose of disentanglement detail such in this example, the disentanglement patterns of the map art style are distributed in the entire images and thus yield distortion to map information.
