What is single image super resolution?

What is single image super resolution?

Abstract—Single image super-resolution (SISR) is a notori- ously challenging ill-posed problem that aims to obtain a high- resolution (HR) output from one of its low-resolution (LR) versions. Recently, powerful deep learning algorithms have been applied to SISR and have achieved state-of-the-art performance.

Why is image super resolution?

Image Super Resolution refers to the task of enhancing the resolution of an image from low-resolution (LR) to high (HR). It is popularly used in the following applications: Surveillance: to detect, identify, and perform facial recognition on low-resolution images obtained from security cameras.

How does super resolution video work?

In general, image super-resolution methods process a single image at a time, while video super-resolution algorithms deal with multiple successive images/frames at a time so as to utilize relationship within frames to super-resolve the target frame.

What is multi image super resolution?

Abstract: Super-resolution (SR) reconstruction is a process aimed at enhancing the spatial resolution of images, either from a single observation, based on the learned relation between low and high resolution, or from multiple images presenting the same scene.

What is Set5 dataset?

The Set5 dataset is a dataset consisting of 5 images (“baby”, “bird”, “butterfly”, “head”, “woman”) commonly used for testing performance of Image Super-Resolution models.

What is Srcnn?

SRCNN[1] proposes a 3 layer CNN for image super-resolution. It is one of the first papers to apply deep neural networks for the task of image super-resolution. The SRCNN architecture is composed of three components: Feature extractor, non-linear mapping, reconstruction.

How good is Super Resolution?

Super Resolution is a new feature that was introduced in Adobe Camera Raw 13.2, and in a nutshell it provides a way of doubling the resolution of images; the height and width of a Raw file, JPEG or TIFF can be doubled to provide four times the original resolution.

What is example based Super Resolution?

Example-based super-resolution [1], also named as single-image super-resolution, is a problem of enhancing the resolution of some low-resolution images with the help of a set of training image pairs. Each of training image pairs consists of a low-resolution image and its corresponding high-resolution image.

What is super resolution monitor?

Simply put, it renders a game at a higher, more detailed resolution and intelligently shrinks the result back down to the resolution of your monitor, giving you 4K, 3840×2160-quality graphics on any screen.

How does Super resolution microscopy work?

The stripes fired at the sample interact with high frequency light produced from the sample. This interaction produces a third pattern that can be more easily analyzed. Using multiple images, further detail is obtained, and an image is reconstructed with around twice the resolution as traditional light microscopy.

What is SR CNN?

In SRCNN, it is used for single image super resolution (SR) which is a classical problem in computer vision.

What is Psnr in deep learning?

Peak Signal-to-Noise Ratio (PSNR) is commonly used objective metric to measure the reconstruction quality of a lossy transformation. PSNR is inversely proportional to the logarithm of the Mean Squared Error (MSE) between the ground truth image and the generated image.
