چکیده

This paper introduces a robust super-resolution algorithm for joint color multi-frame demosaicing. We show that our algorithm, although fast and simple, exhibits convincing results not only within the modeling assumptions, but also for real raw data series. The ultimate goal is its application to telemedical patient monitoring through mobile devices with limited computing power and low quality imaging devices.

Joint demosaicing and super-resolution imaging from a set of unregistered aliased images

We present a new algorithm that performs demosaicing and super-resolution jointly from a set of raw images sampled with a color filter array. Such a combined approach allows us to compute the alignment parameters between the images on the raw camera data before interpolation artifacts are introduced. After image registration, a high resolution color image is reconstructed at once using the full...

Robust super-resolution by fusion of interpolated frames for color and grayscale images

Multi-frame super-resolution (SR) processing seeks to overcome undersampling issues that can lead to undesirable aliasing artifacts in imaging systems. A key factor in effective multi-frame SR is accurate subpixel inter-frame registration. Accurate registration is more difficult when frame-to-frame motion does not contain simple global translation and includes locally moving scene objects. SR p...

Video-to-Video Dynamic Super-Resolution for Grayscale and Color Sequences

We address the dynamic super-resolution (SR) problem of reconstructing a high-quality set of monochromatic or color superresolved images from low-quality monochromatic, color, or mosaiced frames. Our approach includes a joint method for simultaneous SR, deblurring, and demosaicing, this way taking into account practical color measurements encountered in video sequences. For the case of translat...

Pseudo Zernike Moment-based Multi-frame Super Resolution

The goal of multi-frame Super Resolution (SR) is to fuse multiple Low Resolution (LR) images to produce one High Resolution (HR) image. The major challenge of classic SR approaches is accurate motion estimation between the frames. To handle this challenge, fuzzy motion estimation method has been proposed that replaces value of each pixel using the weighted averaging all its neighboring pixels i...

Super-resolution Table of Contents List of Figures

This report describes a multi-frame super-resolution image enhancement algorithm. Images are first aligned using an image registration routine implemented for the project, or with an open source registration library. The latter provides better accuracy. Colour-filtered images from digital cameras need to be demosaiced to restore missing colour information before they can be analyzed. Three demo...
