Synthesizing the Whole View of a Large-Scale Object

Myint Myint Sein, Thin Lai LaiThein
2012 International Journal of Informatics and Communication Technology (IJ-ICT)  
A whole view of the large scale object is reconstructed image by applying the above process successively.  ...  The information of the feature points of an object is obtained from a foreground image and establishing the correspondence among views.  ...  By dividing a non-planar scene into multiple triangular patches, the planar projective transform can be applied for non-planar scene.  ...

View synthesis for pose computation

Pierre Rolin, Marie-Odile Berger, Frédéric Sur
2019 Machine Vision and Applications  
Geometrical registration of a query image with respect to a 3D model, or pose estimation, is the cornerstone of many computer vision applications.  ...  In this paper, we propose to add descriptors to the model, obtained from synthesized views associated with virtual cameras completing the covering of the scene by the real cameras.  ...  View synthesis is also the ground of ASIFT [18] for image matching and of [19] for pose estimation.  ...

Haopeng Li, Markus Flierl
2012 2012 19th IEEE International Conference on Image Processing  
This paper presents a content-adaptive modeling and coding scheme for static multiview background scenes of soccer games.  ...  We propose an approach that uses the Scale Invariant Feature Transform (SIFT) to extract the parameters of the geometric models.  ...  A DIBR approach to virtual view synthesis uses dense depth images, which are usually generated by pixelwise matching [4] .  ...

Video Completion for Indoor Scenes [chapter]

Vardhman Jain, P. J. Narayanan
2006 Lecture Notes in Computer Science  
In this paper, we present a new approach for object removal and video completion of indoor scenes. In indoor images, the frames are not affine related.  ...  The region near the object to be removed can have multiple planes with sharply different motions. Dense motion estimation may fail for such scenes due to missing pixels.  ...  The affine matching is helpful in removing the non-planar regions from considerations.  ...

Natural Image Stitching Using Depth Maps [article]

Tianli Liao, Nan Li
2022 arXiv   pre-print
Natural image stitching (NIS) aims to create one natural-looking mosaic from two overlapping images that capture a same 3D scene from different viewing positions.  ...  Challenges inevitably arise when the scene is non-planar and the camera baseline is wide, since parallax becomes not negligible in such cases.  ...  However, when the 3D scene consists of background objects with non-planar surfaces or even foreground objects with discontinuous depths, meanwhile the baseline is wide, homography cannot generate a natural-looking  ...

24/7 place recognition by view synthesis

Akihiko Torii, Relja Arandjelovic, Josef Sivic, Masatoshi Okutomi, Tomas Pajdla
2015 2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR)  
Second, based on this observation, we develop a new place recognition approach that combines (i) an efficient synthesis of novel views with (ii) a compact indexable image representation.  ...  First, we demonstrate that matching across large changes in the scene appearance becomes much easier when both the query image and the database image depict the scene from approximately the same viewpoint  ...  View synthesis from street-level imagery In this section we describe our view synthesis method that expands the database of the geo-tagged images with additional viewpoints sampled on a regular grid.  ...

Hidden view synthesis using real-time visual SLAM for simplifying video surveillance analysis

C. Mei, E. Sommerlade, G. Sibley, P. Newman, I. Reid
2011 2011 IEEE International Conference on Robotics and Automation  
Augmenting the view is referred to as hidden view synthesis. Compared to previous work, the current approach improves by simplifying the setup and requiring minimal user input.  ...  By exploiting the map, a different moving camera can render hidden views in realtime at 30Hz. We discuss some of the challenges remaining for full automation.  ...  We wish to enrich this view with images from different cameras in the environment to enable synthesising hidden views.  ...
