Multi-example feature-constrained back-projection method for image super-resolution

Computational Visual Media, 2017
Example-based super-resolution algorithms, which predict unknown high-resolution image information using a relationship model learnt from known high- and low-resolution image pairs, have attracted considerable interest in the field of image processing ...

Reconstructing dark energy with model independent methods after DESI DR2

European Physical Journal C: Particles and Fields
In this paper, we employ two model-independent approaches, including redshift binning method and polynomial interpolation method, to reconstruct dark energy (DE) equation of state (EoS) w(z) and DE density function f(z).

A low-overhead repair code based on hybrid grouping

Journal of King Saud University: Computer and Information Sciences
Reed–Solomon (RS) codes are widely adopted in large-scale distributed storage systems due to their optimal storage efficiency. However, repairing failed nodes in RS-based environments often requires intensive matrix inversions, which increase ...
