Parameter-Minimal Neural DE Solvers via Horner Polynomials
T. Matulić, D. Seršić
We propose a parameter-minimal neural architecture for solving differential equations by restricting the hypothesis class to Horner-factorized polynomials, yielding an implicit, di…
Subspace Clustering in Wavelet Packets Domain
Ivica Kopriva, Damir Sersic
Subspace clustering (SC) algorithms utilize the union of subspaces model to cluster data points according to the subspaces from which they are drawn. To better address separability…
Estimating Uncertainty in PET Image Reconstruction via Deep Posterior Sampling
Tin Vlašić, Tomislav Matulić, Damir Seršić
Positron emission tomography (PET) is an important functional medical imaging technique often used in the evaluation of certain brain disorders, whose reconstruction problem is ill…
Accurate 2D Reconstruction for PET Scanners based on the Analytical White Image Model
Tomislav Matulić, Damir Seršić
In this paper, we provide a precise mathematical model of crystal-to-crystal response which is used to generate the white image - a necessary compensation model needed to overcome…
Single-Pixel Compressive Imaging in Shift-Invariant Spaces via Exact Wavelet Frames
Tin Vlašić, Damir Seršić
This paper introduces a novel framework for single-pixel imaging via compressive sensing (CS) in shift-invariant (SI) spaces by exploiting the sparsity property of a wavelet repres…
Sampling and Reconstruction of Sparse Signals in Shift-Invariant Spaces: Generalized Shannon's Theorem Meets Compressive Sensing
Tin Vlašić, Damir Seršić
This paper introduces a novel framework and corresponding methods for sampling and reconstruction of sparse signals in shift-invariant (SI) spaces. We reinterpret the random demodu…
2D PET Image Reconstruction Using Robust L1 Estimation of the Gaussian Mixture Model
Azra Tafro, Damir Seršić, Ana Sović Kržić
An image or volume of interest in positron emission tomography (PET) is reconstructed from pairs of gamma rays emitted from a radioactive substance. Many image reconstruction metho…
Fast low-level pattern matching algorithm
Janja Paliska Soldo, Ana Sovic Krzic, and Damir Sersic
This paper focuses on pattern matching in the DNA sequence. It was inspired by a previously reported method that proposes encoding both pattern and sequence using prime numbers. Al…
