Synthesizing the Whole View of a Large-Scale Object
2012
International Journal of Informatics and Communication Technology (IJ-ICT)
Preserved Fulltext
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. ...

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. ...

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 (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 ...

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. ...
