Affine non-local Bayesian image denoising algorithm
H Xu, X Jia, L Cheng, H Huang - The Visual Computer, 2023 - Springer
This paper proposes an extension of the non-local Bayesian denoising algorithm. The idea
is to use elliptical patches instead of regular square patches in the grou** process. We …

Discrete approximations of the affine Gaussian derivative model for visual receptive fields
The affine Gaussian derivative model can in several respects be regarded as a canonical
model for receptive fields over a spatial image domain:(i) it can be derived by necessity from …

Non-iterative covariant feature extraction based on the shapes of local support regions
L Lu, Y Zhang, K Liu - IEEE Access, 2020 - ieeexplore.ieee.org
Feature extraction is important in image matching. However, the perspective deformations,
especially the anisotropic scaling deformations will affect the performances of feature …
