"RENDERING IMAGE AT NOVEL VIEWPOINT BY IMAGE BASED TECHNIQUES"

By Mr. Yin Li


Abstract:

In this survey, I study image-based techniques to synthesize a new image
at novel viewpoint, without any lighting or environment changing. First, I
approach the problem from the traditional computer graphics point of view,
and compare its pros and cons comparing with image based techniques. The
key difference of these two techniques is that traditional computer
graphics techniques try to simulate the physical process for rendering,
while image based techniques try to infer the color of target pixel from
mapping and interpolation from sampled images. However, geometry
information still plays an important role in imagebased rendering.
Therefore, we study in detail the image based novel view synthesis
algorithms by three category. The first category uses precise 3D geometry
to facilitate the rendering. The second cooperates image samples with
rough 3D geometry, compensating the errors for both. The third renders
novel view using 2D feature correspondence instead of explicitly
representing 3D geometry. I will also propose future work direction along
this line of research.
