Retargeting & Harmonization

Image and video processing and manipulation can benefit from geometric approaches, whether applied to the spatial, temporal or color domain. We use differential representations and variational modeling for various applications in image and video editing, visual media retargeting, image-based rendering and more. For example, we design special warping functions for images and video that are optimized to preserve specific features, such as user-defined areas, salient content, faces, camera and object motion and temporal coherence. Our recent areas of research in this domain include reuse of visual data for creative design via guided texture synthesis or sub-pixel accurate transfer mapping, video-based 3D reconstruction, image and video retargeting for display devices of varying aspect ratios and color spaces, image-based scene navigation.
