Super-Resolution Enhancement of Digital Video
When designing a system for image acquisition, there is generally a desire for high spatial resolution and a wide field of view. To satisfy these competing requirements, a camera system typically must employ small f-number optics, which produces an image with very high spatial-frequency band-width at the focal plane. To avoid aliasing caused by under-sampling, the corresponding focal plane arra...
متن کاملSuper-resolution Enhancement of Video
We consider the problem of enhancing the resolution of video through the addition of perceptually plausible high frequency information. Our approach is based on a learned data set of image patches capturing the relationship between the middle and high spatial frequency bands of natural images. By introducing an appropriate prior distribution over such patches we can ensure consistency of static...
متن کاملImproving Super-Resolution Enhancement of Video by using Optical Flow
In the literature there has been much research into two methods of attacking the super-resolution problem: using optical flow-based techniques to align low-resolution images as samples of a target high-resolution image, and using learning-based techniques to estimate perceptuallyplausible high frequency components of a low-resolution image. Both of these approaches have been naturally extended ...
متن کاملSuper Sampling of Digital Video
Certain imaging applications can exploit features beyond the spatial resolution of a sensor through computational super-resolution techniques. One particular method, super-sampling, involves assimilating multiple frames of digital video into composite video frames of higher average sampling density than the original sensor. Under certain conditions of scene motion and sensor characteristics, th...
متن کاملSuper-resolution from compressed video
The problem of recovering a high-resolution frame from a sequence of low-resolution and compressed images is considered. The presence of the compression system complicates the recovery problem, as the operation reduces the amount of frequency aliasing in the low-resolution frames and introduces a non-linear noise process. Increasing the resolution of the decoded frames can still be addressed in...
