Medical image registration methods which use mutual information as similarity measure have been improved in recent decades. Mutual Information is a basic concept of Information theory which indicates the dependency of two random variables (or two images). In order to evaluate the mutual information of two images their joint probability distribution is required. Several interpolation methods, su...

In this paper, we propose an effective color filter array (CFA) interpolation method for digital still cameras (DSCs) using a simple image model that correlates the channels. In this model, we define the constants as green minus red and as green minus blue. For real-world images, the contrasts of and are quite flat over a small region and this property is suitable for interpolation. The main co...

In this paper, we present an interpolation framework for structure-preserving model order reduction of parametric bilinear dynamical systems. We introduce a general setting, covering broad variety different structures systems, and then provide conditions on projection spaces the structured subsystem transfer functions such that system structure parameter dependencies are preserved in reduced-or...

This paper proposes a fast and effective image interpolation algorithm using median filter. The interpolation algorithm is composed of two steps. First, a non-linear iterative procedure is utilized to interpolate the pixel whose direction can be easily determined by local information. Second, according to the introduced assumption that image interpolation can be regarded as a local image filter...

An interpolated 3-D digital waveguide mesh algorithm is elaborated. We introduce an optimized technique that improves a formerly proposed interpolated 3-D mesh and renders the 3-D mesh more homogeneous in different directions. Frequency-warping techniques are used to shift the frequencies of the output signal of the mesh in order to cancel the effect of dispersion error. The extensions improve ...
