Multi-resolution image inpainting
2003 International Conference on Multimedia and Expo. ICME '03. Proceedings (Cat. No.03TH8698), 2003Digital inpainting is an image interpolation mechanism, which can automatically restore damaged or partially removed image. Most inpainting mechanisms use a singular resolution approach on the extrapolation or interpolation of pixels. We propose a multi-resolution algorithm, which can take into consideration the different levels of details.

Super-Resolution Imaging and Plasmonics
Chemical Reviews, 2017This review describes the growing partnership between super-resolution imaging and plasmonics, by describing the various ways in which the two topics mutually benefit one another to enhance our understanding of the nanoscale world. First, localization-based super-resolution imaging strategies, where molecules are modulated between emissive and ...

Scalable Super-Resolution Imaging
2006 IEEE International Conference on Systems, Man and Cybernetics, 2006In this study, we have developed a novel method to obtain high resolution images using an ordinary digital camera. Using successively taken images, our fusion algorithm has a profound effect in the quality of the image which contains richer independent pixels than the originals do.

Improving resolution by image registration
CVGIP: Graphical Models and Image Processing, 1991Abstract Image resolution can be improved when the relative displacements in image sequences are known accurately, and some knowledge of the imaging process is available. The proposed approach is similar to back-projection used in tomography. Examples of improved image resolution are given for gray-level and color images, when the unknown image ...

Super-resolution in PET imaging
IEEE Transactions on Medical Imaging, 2006This paper demonstrates a super-resolution method for improving the resolution in clinical positron emission tomography (PET) scanners. Super-resolution images were obtained by combining four data sets with spatial shifts between consecutive acquisitions and applying an iterative algorithm.

Super-Resolution Approach to Increasing the Resolution of Image
2014Super-resolution (SR) is a class of techniques that enhance the resolution of an imaging system by combining complimentary information from several images to produce high resolution images of a subject. Fast non-iterative and iterative algorithms are described in this article. The metrics to compare the images are investigated also. In conclusion shows

Resolution of a Paradox with After Images
Nature, 1971Two weeks ago I described the results of flash bleaching the retina with a bright uniform field seen through a set of neutral filters as shown in Fig. 1b. Ten minutes later cones had quite recovered and only rods contributed to the after image. This was observed by briefly opening the eyes from time to time and looking at a faintly illuminated white ...

Imaging model at different resolutions
ISSPA '99. Proceedings of the Fifth International Symposium on Signal Processing and its Applications (IEEE Cat. No.99EX359), 2003Multiresolution analysis is being extensively used in image processing and computer vision problems. We derive the image formation model at a coarse resolution given the image model at a fine resolution, in particular we give an expression to calculate the blur matrix at a coarse resolution given the blur matrix at fine resolution, In particular, we ...

Image and Vision Computing, 2006
Abstract The shortcomings in commonly used kernel-based super-resolution drive the study of improved super-resolution algorithms of higher quality. In the past years a wide range of very different approaches has been taken to improve super-resolution.

Resolution Limitations in Holographic Images
Applied Optics, 1969The maximum resolution in the images of a given object produced by the holographic method using a single record in which only one wave parameter is stored at each point on the wavefront is shown to be one-half as great as that which could be obtained without any increase in the size or resolution capability of the recording if two parameters were ...
