Super-resolution Image Processing Pipeline
this project describes the steps to process a Bayer raw sensor output image which is noisy, undersampled, and blurred. The final output is a de-noised, de-blurred, and upsampled version of the input image. Some of the in-between steps include lens shading correction, color balancing, demosaicing, color correction, etc. Keywords—raw image ; deblurring ; denoising ; image deconvolution ;
متن کاملImage Interpolation by Super-Resolution
Term “super-resolution” is typically used for a high-resolution image produced from several low-resolution noisy observations. In this paper, we consider the problem of high-quality interpolation of a single noise-free image. Several aspects of the corresponding super-resolution algorithm are investigated: choice of regularization term, dependence of the result on initial approximation, converg...
متن کاملSuper-resolution and Raman chemical imaging: from multiple low resolution images to a high resolution image.
Imaging in Raman spectroscopy is a valuable tool for analytical chemistry. Although molecular characterization at micron level is achieved for many applications, it usually fails producing chemical images of micron size samples as expected in chemical, environmental and biological analysis. The aim of the work is to introduce the potential of super-resolution in vibrational spectroscopic imagin...
متن کاملApplication of Super-Resolution Image Reconstruction to Digital Holography
We describe a new application of super-resolution image reconstruction to digital holography which is a technique for threedimensional information recording and reconstruction. Digital holography has suffered from the low resolution of CCD sensors, which significantly limits the size of objects that can be recorded. The existing solution to this problem is to use optics to bandlimit the object ...
متن کاملImage Super-Resolution by Vectorizing Edges
As the resolution of output device increases, the demand of high resolution contents has become more eagerly. Therefore, the image superresolution algorithms become more important. In digital image, the edges in the image are related to human perception heavily. Because of this, most recent research topics tend to enhance the image edges to achieve better visual quality. In this paper, we propo...
