Analysis of time-frequency scattering transforms
Wojciech Czaja, Weilin Li
In this paper we address the problem of constructing a feature extractor which combines Mallat's scattering transform framework with time-frequency (Gabor) representations. To do t…
Symbolic Tensor Calculus -- Functional and Dynamic Approach
A. Woszczyna, P. Plaszczyk, W. Czaja +1
In this paper, we briefly discuss the dynamic and functional approach to computer symbolic tensor analysis. The ccgrg package for Wolfram Language/Mathematica is used to illustrate…
Superresolution of Noisy Remotely Sensed Images Through Directional Representations
Wojciech Czaja, James M. Murphy, Daniel Weinberg
We develop an algorithm for single-image superresolution of remotely sensed data, based on the discrete shearlet transform. The shearlet transform extracts directional features of…
Discrete Directional Gabor Frames
Wojciech Czaja, Benjamin Manning, James M. Murphy +1
We develop a theory of discrete directional Gabor frames for functions defined on the -dimensional Euclidean space. Our construction incorporates the concept of ridge functions…
