A non-adaptive image interpolation algorithm is proposed to scale images for any given scaling factor with an enhancement scheme to ensure a better picture. |In the proposed algorithm, two reference frames, one with higher resolution and another with lower resolution are generated using an original videoframefor the User defined scaling factor. Later, two Intermediate frames are generated from ...

As an application of Hirota bilinear method, perturbation expansion truncated at different levels is used to obtain exact soliton solutions to (2+1)-dimensional nonlinear evolution equation in much simpler way in comparison to other existing methods. We have derived bilinear form of nonlinear evolution equation and using this bilinear form, bilinear Backlund transformations and construction of ...

Let $A$ be an abelian topological group and $B$ a trivial topological $A$-module. In this paper we define the second bilinear cohomology with a trivial coefficient. We show that every abelian group can be embedded in a central extension of abelian groups with bilinear cocycle. Also we show that in the category of locally compact abelian groups a central extension with a continuous section can b...

In this paper, we present a general framework to construct recurrent fractal interpolation surfaces (RFISs) on rectangular grids. Then introduce bilinear RFISs, which are easy be generated while there no restrictions points and vertical scaling factors. We also obtain the box dimension of RFISs under certain constraints, where main assumption is that factors have uniform sums compatible partiti...

We proposed an intensity-based morphological pyramid image registration algorithm. This approach utilizes the global affine transformation model, also considering radiometric changes between images. With the morphological pyramid structure, Levenberg-Marquardt optimization, and bilinear interpolation, this algorithm can be implemented hierarchically and iteratively with capability of measuring,...

This talk summarizes results for all the scale independent renormalization constants for bilinear currents (ZA, ZV , and ZS/ZP ), the improvement constants (cA, cV , and cT ), the quark mass dependence of ZO , and the coefficients of the equation of motion operators for O(a) improved lattice QCD. Using data at β = 6.0, 6.2 and 6.4 we study the scaling behavior of these quantities and quantify r...

We decompose a matrix Y into a sum of rank one bilinear forms in a stepwise manner, by considering Y as a mapping from the finite dimensional space l r to the space l p . We provide transition formulas, and represent them in a duality diagram, thus generalizing the well known duality diagram in the french school of data analysis. As an application, we introduce a family of Euclidean multidimens...

We provide a new analysis of the Boltzmann equation with constant collision kernel in two space dimensions. The scaling-critical Lebesgue is $$L^2_{x,v}$$ ; we prove global well-posedness and version scattering, assuming that data $$f_0$$ sufficiently smooth localized, norm small. proof relies upon bilinear spacetime estimate for “gain” term Boltzmann’s equation, combined novel application Kani...
