Preconditioning for Temporal Video Superresolution
نویسندگان
چکیده
Temporal superresolution produces a video sequence of high temporal resolution (HTR), i.e. frame rate, from a set of video sequences of low temporal resolution (LTR). A method for preconditioning large systems of linear equations arising in temporal video superresolution problems is presented. We show that circulant block preconditioners can accelerate the convergence of iterative techniques such as the conjugate gradient method when solving such problems. Simulations demonstrate the effectiveness of our approach.

A New Wavelet Based Spatio-temporal Method for Magnification of Subtle Motions in Video
Video magnification is a computational procedure to reveal subtle variations during video frames that are invisible to the naked eye. A new spatio-temporal method which makes use of connectivity based mapping of the wavelet sub-bands is introduced here for exaggerating of small motions during video frames. In this method, firstly the wavelet transformed frames are mapped to connectivity space a...
متن کاملA Wavelet-based Interpolation-restoration Method for Superresolution (wavelet Superresolution)*
Superresolution produces high-quality, high-resolution images from a set of degraded, low-resolution images where relative frame-to-frame motions provide different looks at the scene. Superresolution translates data temporal bandwidth into enhanced spatial resolution. If considered together on a reference grid, given low-resolution data are nonuniformly sampled. However, data from each frame ar...
