Lossy compression algorithms Revolvy Brain revolvybrain. Since data points are represented by the index of their closest centroid, commonly occurring data have low error, and linds-buzo-gray data high error. Delaunay triangulations maximize the minimum angle of all the angles of the triangles in the triangulation; they tend to avoid sliver triangles.
That set of points called seeds, sites, or generators is specified beforehand, and for each seed there is a corresponding region consisting of all points closer to that seed than to any other. Delaunay triangulation topic A Delaunay triangulation in the plane with circumcircles shown In mathematics and computational geometry, a Delaunay triangulation also known as a Delone triangulation for a given set P of discrete points in a plane is a triangulation DT P such that no point in P is inside the circumcircle of any triangle in DT P.

The difference between the original signal and the reconstructed signal is the quantization error and, in this simple quantization scheme, is a alorithm function of the input signal.
