Example-Based Super-Resolution
The Problem: Pixel representations for images do not have resolution independence. When we zoom into a bitmapped image, we get a blurred image. Figure 1 shows the problem for a teapot image, rich with real-world detail. We know the teapot’s features should remain sharp as we zoom in on them, yet standard pixel interpolation methods, such as pixel replication (b, c) and cubic spline interpolatio...
متن کاملHybrid Example-Based Single Image Super-Resolution
Image super-resolution aims to recover a visually pleasing high resolution image from one or multiple low resolution images. It plays an essential role in a variety of real-world applications. In this paper, we propose a novel hybrid example-based single image super-resolution approach which integrates learning from both external and internal exemplars. Given an input image, a proxy image with ...
متن کاملExample-based super-resolution via social images
A novel image patch based example-based super-resolution algorithm is proposed for benefitting from social image data. The proposed algorithm is designed based on matrix-value operator learning techniques where the image patches are understood as the matrices and the single-image super-resolution is treated as a problem of learning a matrix-value operator. Taking advantage of the matrix trick, ...
متن کاملP Example-based Approaches Image-based Modeling, Rendering, and Lighting Example-based Super-resolution
objects offer resolution independence over a wide range of scales. With this approach, object boundaries remain sharp when we zoom in on an object until very close range, where faceting appears due to finite polygon size (see Figure 1). However, constructing polygon models for complex, real-world objects can be difficult. Imagebased rendering (IBR), a complementary approach for representing and...
متن کاملSome medical applications of example-based super-resolution
Example-based super-resolution (EBSR) [3, 4] reconstructs a highresolution image from a low-resolution image, given a training set of high-resolution images. In this note I propose some applications of EBSR to medical imaging. A particular interesting application, which I call x-ray voxelization, approximates the result of a CT scan from an x-ray image. 1 Example-based super-resolution Example-...
