Silhouette backprojection is a mapping from an epipolar plane to a polar coordinate parametric slice plane. A cosine curve on the epipolar plane corresponds to a single point on the parametric plane. If we resample the silhouette intensities along the curve in a constant interval, then the topological information on the epipolar plane is lost. We use laplacian backprojection as well as the traditional silhouette backprojection to utilize the coherence on the epipolar plane and to sharpen the silhouette slice image.
