We developed a method to obtain corner points for healthier point matching using corner properties such as corner angle, corner orientation and contrast. A large corner point set, obtained by a common corner detector (Harris, Tomasi-Kanade etc.) is given to our algorithm as input. Then, the corner properties are extracted for this point set in terns of image derivatives. Cornerness measure calculated from the image is compared with the one calculated using an ideal corner with the extracted properties. If they are close enough, which shows that the neighborhood of the point possess corner properties and estimations are successful, the corner is selected. It is presumed that corners selected by this method are more suitable for point matching. Moreover, extracted corner properties can be used as a priori information for matching.

Simulation of dynamic crack growth using the generalized interpolation material point (GIMP) method Daphalapurkar, Nitin P.; Lu, Hongbing; Çöker, Demirkan; Komanduri, Ranga (Springer Science and Business Media LLC, 2007-01-01) Dynamic crack growth is simulated by implementing a cohesive zone model in the generalized interpolation material point (GIMP) method. Multiple velocity fields are used in GIMP to enable handling of discrete discontinuity on either side of the interface. Multilevel refinement is adopted in the region around the crack-tip to resolve higher strain gradients. Numerical simulations of crack growth in a homogeneous elastic solid under mode-II plane strain conditions are conducted with the crack propagating along...
Transformation-based metamaterials to eliminate the staircasing error in the finite difference time domain method Ozgun, Ozlem; Kuzuoğlu, Mustafa (Wiley, 2012-07-01) A coordinate transformation technique is introduced for the finite difference time domain method to alleviate the effects of errors introduced by the staircasing approximation of curved geometries that do not conform to a Cartesian grid. An anisotropic metamaterial region, which is adapted to the Cartesian grid and designed by the coordinate transformation technique, is constructed around the curved boundary of the object, and the region occupied between the curved boundary and the inner boundary of the ani...
Scale invariant representation of 2 5D data AKAGUNDUZ, Erdem; ULUSOY PARNAS, İLKAY; BOZKURT, Nesli; Halıcı, Uğur (2007-06-13) In this paper, a scale and orientation invariant feature representation for 2.5D objects is introduced, which may be used to classify, detect and recognize objects even under the cases of cluttering and/or occlusion. With this representation a 2.5D object is defined by an attributed graph structure, in which the nodes are the pit and peak regions on the surface. The attributes of the graph are the scales, positions and the normals of these pits and peaks. In order to detect these regions a "peakness" (or pi...
Biased Proportional Navigation with Exponentially Decaying Error for Impact Angle Control and Path Following Erer, Korav S.; Tekin, Raziye; Özgören, Mustafa Kemal (2016-06-24) In this paper, a bias term to enhance proportional navigation is designed through an error signal that is a function of pursuit angles with the objective of accommodating both the problem of impact angle control against a stationary target and the problem of path following using the virtual target concept. The design leads to a second order transfer function describing the linear error dynamics contained within the nonlinear environment. The performance of the proposed guidance law is demonstrated in a comp...
Continuous-time nonlinear estimation filters using UKF-aided gaussian sum representations Gökçe, Murat; Kuzuoğlu, Mustafa; Department of Electrical and Electronics Engineering (2014) A nonlinear filtering method is developed for continuous-time nonlinear systems with observations/measurements carried out in discrete-time by means of UKFaided Gaussian sum representations. The time evolution of the probability density function (pdf) of the state variables (or the a priori pdf) is approximated by solving the Fokker-Planck equation numerically using Euler’s method. At every Euler step, the values of the a priori pdf are evaluated at deterministic sample points. These values are used with Ga...
