Image enhancement by nonlinear extrapolation in frequency space
A technique for enhancing the perceptual sharpness of an image is described. The enhancement algorithm augments the frequency content of the image using shape-invariant properties of edges across scale by using a nonlinearity that generates phase coherent higher harmonics. The procedure utilizes the Laplacian transform and the Laplacian pyramid image representation. Results are presented depict...
متن کاملResolution Enhancement in Magnetic Resonance Imaging by Frequency Extrapolation
This thesis focuses on spatial resolution enhancement of magnetic resonance imaging (MRI). In particular, it addresses methods of performing such enhancement in the Fourier domain. After a brief review of Fourier theory, the thesis reviews the physics of the MRI acquisition process in order to introduce a mathematical model of the measured data. This model is later used to develop and analyze m...
متن کاملImage enhancement by nonlinear wavelet
In this paper we describe how the theory of wavelet thresholding introduced by Donoho and Johnstone can successfully be applied to two distinct problems in image processing where traditional linear ltering techniques are insuucient. The rst application is related to speckle reduction in coherent imaging systems. We show that the proposed method works well for reducing speckle in SAR images whil...
متن کاملColor Image Enhancement by Histogram Equalization in Heterogeneous Color Space
This paper presents a luminosity conserving and contrast enhancing histogram equalization method for color images. The histogram equalization is one of the ordinary methods employed for enhancing contrast in TV and images for consumer electronics where unwanted subjective deterioration are frequently occur. Although there have been many solutions to overcome the drawback of histogram equalizati...
متن کاملOrthogonality Deficiency Compensation for Improved Frequency Selective Image Extrapolation
This paper describes a very efficient algorithm for image signal extrapolation. It can be used for various applications in image and video communication, e. g. the concealment of data corrupted by transmission errors or prediction in video coding. The extrapolation is performed on a limited number of known samples and extends the signal beyond these samples. Therefore the signal from the known ...
