Edge Direction Preserving Image Zooming : A Mathematical andNumerical
We focus in this paper on some reconstruction/restoration methods which aim is to improve the resolution of digital images. The main point is here to study the ability of such methods to preserve 1D structures. Indeed such structures are important since they are often carried by the image "edges". We rst focus on linear methods, give a general framework to design them and show that the preserva...
متن کاملEdge structure preserving image denoising
Image denoising is important in image analysis. It is often used for pre-processing images so that subsequent image analysis is more reliable. Besides noise removal, one important requirement for image denoising procedures is that they should preserve true image structures, such as edges. This paper proposes a novel denoising procedure which can preserve edges and major edge features (e.g., ang...
متن کاملEdge-Forming Methods for Image Zooming: Color Images
This article introduces edge-forming schemes for image zooming of color images by general magnification factors. In order to remove/reduce artifacts arising in image interpolation such as image blur and the checkerboard effect, an edge-forming method is suggested to be applied as a post-process of standard interpolation methods. The method is based on non-convex nonlinear partial differential e...
متن کاملWavelet Domain Image Restoration Using Edge Preserving
In this paper we consider a wavelet-based edge preserving regularization scheme for use in linear image restoration problems. Our efforts build on a collection of mathematical results indicating that wavelets are especially useful for representing functions that contain discontinuities (i.e. edges in two dimensions or jumps in 1D). We interpret the resulting theory in a statistical signal proce...
متن کاملEdge-preserving Regularization in Image Restoration
The reconstruction of an image u(x, y) that describes a real scene from experimental data (observed image) I(x, y) can be identified as an inverse problem. This problem is generally ill-posed in the sense of Hadamard. The regularization of an inverse problem in image processing requires smoothing homogeneous areas of the object without degrading edges. The location of these edges are unknown an...
