If z1, z2, . . . , zn are complex numbers in the open unit disk D and A1, A2, . . . , An are N ×N matrices, let F denote the family of analytic functions, bounded in D, such that for each F ∈ F , F (zk) = Ak, k = 1, 2, . . . , n. We consider ρ = infF∈F supz∈D |F (z)|sp where | · |sp denotes the spectral radius. H. Bercovici has raised the question whether this infimum is attained. We will show ...

In this paper, a new wavelet based image interpolation algorithm is proposed for remote sensing images. Remote sensing images include many mid and high frequency elements such as aerial and satellite photograph images. These frequency elements contain important information. Because conventional interpolation techniques have blurring or blocking effects, the quality of interpolated remote sensin...

In this paper, we propose two adaptive interlaced-to-progressive conversion techniques in which the adequacy of the estimated motion vector is evaluated. If the motion vector is unlikely to give a good temporal motion compensated interpolation result, spatial interpolation is favored or selected to avoid temporal artifacts. In the rst proposed interlaced-to-progressive conversion technique, cal...

In this paper, a de-interlacing technique using motion compensated interpolation is proposed. In the proposed scheme motion estimation is first performed between the same parity field i.e., reference and current field from either odd or even fields. Compared to other motion adaptive and motion compensated interpolation technique this method results in a better visual quality due to an accurate ...

We propose an interpolation-free sub-pixel Motion Estimation (ME) technique that particularly aims at providing accurate Motion Vectors (MVs), where conventional sub-pixel interpolation ME algorithms used in video coding are too complex and time consuming. The proposed algorithm is a combination of block matching algorithms and simplified optical flow, which is Taylor approximation. The techniq...

Image inpainting is the art of predicting damaged regions of an image. The manual way of image inpainting is a time consuming. Therefore, there must be an automatic digital method for image inpainting that recovers the image from the damaged regions. In this paper, a novel statistical image inpainting algorithm based on Kriging interpolation technique was proposed. Kriging technique automatical...

Inpainting is a method for repairing damaged images or to remove unwanted parts of an image. While this process has been performed by professional artists in the past, today, the use of this technology is emerging in the medical area – especially in the medical imaging realm. In this study, the proposed inpainting method uses a radial basis function (RBF) interpolation technique. We first expla...

Image interpolation is a procedure used in expanding and contracting digital images. Image interpolation is referred by various terminologies such as image scaling, image resizing, image resampling, digital zooming, image magnification or enhancement. Image interpolation is widely used in many consumer application devices such as charge-coupled device (CCD) camera, closed circuit television (CC...

due to substantial effect of classification of resource models on future mine planning, one should come with an accurate method of estimation to guarantee that the minimum error is acquired in the estimation process. the known world class cu-mo deposit, sarcheshmeh porphyry deposit (central iran) selected as the study area. the hypogene zone of the deposit was chosen as the space in which estim...
