WebAug 22, 2014 · The Extended Gaussian Image • We can extend the Gaussian image by • placing a mass at each point on the sphere equal to the area of the surface having the given normal • masses are represented by vectors parallel to the normals, with length equal to the mass • An example: EGI of Block Block WebB = imgaussfilt (A) filters image A with a 2-D Gaussian smoothing kernel with standard deviation of 0.5, and returns the filtered image in B. example. B = imgaussfilt (A,sigma) filters image A with a 2-D Gaussian smoothing kernel with standard deviation specified by sigma. B = imgaussfilt ( ___,Name,Value) uses name-value arguments to control ...
WebThe idea is based on the representation of three-dimensional objects by their Extended Gaussian Image (EGI). The EGI is constructed by mapping each surface normal of any object to the Gaussian sphere. Web1 Lecture 23: Gaussian Image and Extended Gaussian Image, Solids of Rev-olution, Direction Histograms, Regular Polyhedra. In this lecture, we cover more on the Gaussian images and extended Gaussian images (EGI), as well as integral Gaussian images, some properties of EGI, and applications of these frameworks. 1.1
Webobject will be its Extended Circular Image representation, the two-dimensional equivalent of the Extended Gaussian Image. This approach will work only for convex polygons, for which the ECI is unique. To morph non-convex polygons, one would have to separate them into convex components and morph each separately, or use an extended version
