Wavelet Superresolution and Quasi-superresolution in Robot Vision
This article presents results of image enhancement for robot vision. Results are obtained by superresolution techniques in wavelet domain. The calculated motion of wavelet coefficients in stationary image can enhance image quality. It can be used as interpolation information for increasing resolution. This is basis for wavelet quasi-superresolution, where one low-resolution image is interpolate...
متن کاملA Wavelet-based Interpolation-restoration Method for Superresolution (wavelet Superresolution)*
Superresolution produces high-quality, high-resolution images from a set of degraded, low-resolution images where relative frame-to-frame motions provide different looks at the scene. Superresolution translates data temporal bandwidth into enhanced spatial resolution. If considered together on a reference grid, given low-resolution data are nonuniformly sampled. However, data from each frame ar...
متن کاملMotion-Free Superresolution
In this paper, we examine the theory of motion-free superresolution by formulating the problem in the Discrete Time Fourier Transform (DTFT) and the Discrete Fourier Transform (DFT) domain. Our approach provides some new insights into how aliasing and blurring can effect exact reconstruction of the superresolved image. For ease of understanding, the analysis, is initially carried out in the 1-D...
متن کاملEstimation of Superresolution Performance
Introduction: Recently, it has been proposed that sensitivity modulations of the receiver coils might lead to an improved image resolution (superresolution) by alteration of the standard reconstruction method [1]. Simulation results and initial experimental evidence [2] have shown that low-resolution imaging modalities like magnetic resonance spectroscopic imaging potentially profit more than h...
متن کاملSuperresolution microscopy for microbiology.
This review provides a practical introduction to superresolution microscopy from the perspective of microbiological research. Because of the small sizes of bacterial cells, superresolution methods are particularly powerful and suitable for revealing details of cellular structures that are not resolvable under conventional fluorescence light microscopy. Here we describe the methodological concep...
