Example-Based Super-Resolution Using Internet Photo Collection

Example-based super-resolution is an image interpolation algorithm which uses a database of training images to create plausible high-frequency details in zoomed images [Freeman et al. 2002]. The algorithm is fairly simple, however its performance heavily depends on the database. In particular, when the characteristics of a target image to be magnified are different from the training images, the...

Example-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, ...

An Example-Based Super-Resolution Algorithm for Selfie Images.

A selfie is typically a self-portrait captured using the front camera of a smartphone. Most state-of-the-art smartphones are equipped with a high-resolution (HR) rear camera and a low-resolution (LR) front camera. As selfies are captured by front camera with limited pixel resolution, the fine details in it are explicitly missed. This paper aims to improve the resolution of selfies by exploiting...

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...

Super-resolution of Defocus Blurred Images

Super-resolution is a process that combines information from some low-resolution images in order to produce an image with higher resolution. In most of the previous related work, the blurriness that is associated with low resolution images is assumed to be due to the integral effect of the acquisition device’s image sensor. However, in practice there are other sources of blurriness as well, inc...
