متن کاملA Framelet-based Algorithm for Video Enhancement
Video clips are made up of many still frames. Most of the times, the frames are small perturbations of their neighboring frames. Recently, we proposed a framelet-based algorithm to enhance the resolution of any frames in a video clip by solving it as a super-resolution image reconstruction problem. In this paper, we extend the algorithm to video enhancement, where we compose a high-resolution v...
متن کاملHigh Precision Object Segmentation and Tracking for use in Super Resolution Video Reconstruction
Super resolution image reconstruction allows for the enhancement of images in a video sequence that is superior to the original pixel resolution of the imager. Difficulty arises when there are foreground objects that move differently than the background. A common example of this is a car in motion in a video. Given the common occurrence of such situations, super resolution reconstruction become...
متن کاملA super-resolution reconstruction algorithm for hyperspectral images
The spatial resolution of a hyperspectral image is often coarse because of the limitations of the imaging hardware. Super-resolution reconstruction (SRR) is a promising signal post-processing technique for hyperspectral image resolution enhancement. This paper proposes a maximum a posteriori (MAP) based multi-frame super-resolution algorithm for hyperspectral images. Principal component analysi...
متن کاملHigh-Resolution Image Reconstruction from Digital Video by Exploitation of Nonglobal Motion
Many imaging systems utilize detector arrays that do not sample the scene according to the Nyquist criterion. As a result, the higher spatial frequencies admitted by the optics are aliased. This creates undesirable artifacts in the imagery. Furthermore, the blurring effects of the optics and the finite detector size also degrade the image quality. Several approaches for increasing the sampling ...
