What is Real-time View Synthesis Using Commodity Graphics Hardware about?

We present a novel use of commodity graphics hardware that effectively combines a plane-sweeping algorithm ] and view synthesis in a single step for real-time, on-line 3D view synthesis. Unlike typical stereo algorithms that use image-based metrics to estimate depths, we focus on using image-based metrics to directly estimate images. Using real-time imagery from a few calibrated cameras, our method can generate new images from nearby viewpoints, without any prior geometric information or requiring any user interaction, in real time and on line.For a desired new view Cn, we discretize the 3D space into a number of candidate focal planes {Di} parallel to the image plane Cn of the desired view. These candidate planes discretize each desired view ray into a finite set of sample points. We step through the set of candidate focal planes, looking for the sample point along each view ray that offers the maximum color consistency among input images. Each final image pixel is determined by the color at this point of maximum consistency.To accomplish this, for each candidate plane Di we project (texture) the input images onto that plane. We then render the resulting textured plane onto the im
