By Peer Stelldinger (auth.), Ullrich Köthe, Annick Montanvert, Pierre Soille (eds.)

This ebook constitutes the refereed complaints of the 1st Workshop on purposes of Discrete Geometry and Mathematical Morphology, WADGMM 2010, held on the overseas convention on development attractiveness in Istanbul, Turkey, in August 2010. The eleven revised complete papers awarded have been rigorously reviewed and chosen from 25 submissions. The publication was once in particular designed to advertise interchange and collaboration among specialists in discrete geometry/mathematical morphology and capability clients of those equipment from different fields of photograph research and development recognition.

Illuminating, generally praised booklet on analytic geometry of circles, the Moebius transformation, and 2-dimensional non-Euclidean geometries.

Geometric tomography bargains with the retrieval of knowledge a couple of geometric item from facts bearing on its projections (shadows) on planes or cross-sections via planes. it's a geometric relative of automated tomography, which reconstructs a picture from X-rays of a human sufferer. the topic overlaps with convex geometry and employs many instruments from that region, together with a few formulation from critical geometry.

First Steps in Differential Geometry: Riemannian, Contact, Symplectic (Undergraduate Texts in Mathematics)

Differential geometry arguably deals the smoothest transition from the traditional collage arithmetic series of the 1st 4 semesters in calculus, linear algebra, and differential equations to the better degrees of abstraction and evidence encountered on the higher department via arithmetic majors. this present day it's attainable to explain differential geometry as "the research of buildings at the tangent space," and this article develops this standpoint.

4(c). Then, we can consider the discrete lengths (Lhj i ,x0 ,y0 ) of the maximal segments on the subsampled shapes φxi 0 ,y0 (C) containing fix0 ,y0 (P ) with the increasing sequence of digitization grid steps hi = ih (see Fig. 4(a,b)). For a given subsampling size i, the average digital length of all the maximal hi segments containing the subsampled pixel is denoted as L . n (see Fig. 7(a,b)). According to (4) (resp. (5)), if P is located on a curved (resp. flat) part, the slope of an affine approximation of the multiscale profile should be in [− 21 , − 13 ] (resp.

P be the normal vector to n Let S be a smooth surface (at least C 2 ). Let − the surface at a point p. Let Π be the plane which contains the normal vector − →p . Plane Π intersects S at a curve C containing p: the curvature kp of C at n →p , curve point p is called normal curvature at p. When plane Π turns around − n C varies. There are two extremal curvature values k1 (p) ≤ k2 (p) which bound the curvature values of all curves C. The corresponding curves C1 and C2 are orthogonal at point p [5].

E. with coarser and coarser grid steps. , n and with shift x0 , y0 . Several subsampling processes can be considered at this stage, but it is necessary to maintain a surjective map fix0 ,y0 which associates any point P of C to its image point in the subsampled contour φxi 0 ,y0 (C). Such a function is illustrated on Fig. 4(c). Then, we can consider the discrete lengths (Lhj i ,x0 ,y0 ) of the maximal segments on the subsampled shapes φxi 0 ,y0 (C) containing fix0 ,y0 (P ) with the increasing sequence of digitization grid steps hi = ih (see Fig.
