چکیده
A data-drivcn approach is proposcd to rccognizc a family of planar ohjcc~s, which arc strctchcd along the axis of symmctry and arc partially ohscurcd, using hightuwaturc points, samplcd boundary distanccs (SBD) and a statistical mcthotl. cross correlation. In this work, thc SBD's arc thc distanccs mcasurcd to thc boundary points of an ohjcct from points cqually spaced along a linc which is cithcr a symmctric axis or assumcd to hc a symmctric axis. A rncthod for dctccting symmcuy and finding axis of symmcuy of partially ohscurcd ohjccts is prcscntcd. Thc cxpcrimcntal rcsulL~ arc also prcscntcd.

Recognition of Partially Occluded Elliptical Objects using Symmetry on Contour
There are many research efforts in object recognition. Most existing methods for object recognition are based on full objects. However, many images contain multiple objects with occluded shapes and regions. Due to the occlusion of objects, image retrieval can provide incomplete, uncertain, and inaccurate results. To resolve this problem, we propose a new method to reconstruct objects using symm...
متن کاملInterval number ranking method considering multiple decision attitudes
Many interval number ranking methods cannot representthe different attitudes of decision makers with different riskappetites. Therefore, interval numbers are expressed in the RectangularCoordinate System (RCS). After mining the interval numbers in the RCS,the Symmetry Axis Compensation Factor, which is known as (lambda),was introduced, and the Equivalent Function o...

The Ernst equation is formulated on an arbitrary Riemann surface. Analytically, the problem reduces to finding solutions of the ordinary Ernst equation which are periodic along the symmetry axis. The family of (punctured) Riemann surfaces admitting a non-trivial Ernst field constitutes a " partially discretized " subspace of the usual moduli space. The method allows us to construct new exact so...
متن کاملOptimization of Conformal Mapping Functions used in Developing Closed-Form Solutions for Underground Structures with Conventional cross Sections
Elastic solutions applicable to single underground openings usually suffer from geometry related simplification. Most tunnel shapes possess two axes of symmetry while a wide range of geometries used in tunneling practice involve only one symmetry axis. D-shape or horse-shoe shape tunnels and others with arched roof and floor are examples of the later category (one symmetry axis). In the present...
متن کاملArticle title :
RGC-sm is a state model proposed to describe complex-shaped objects within the family of right generalized cylinders (RGCs). A continuous deformation of a planar curve (contour) along the object's axis describes its surface. The contour, locally orthogonal to the axis, is modeled by a finite Fourier series (FS). The zero-order FS harmonics (contour centers) define the axis. The object is divide...
