Fast image registration with non-stationary Gauss-Markov random field templates
TL;DR: This paper proposes a framework for registering images to a non-stationary Gauss-Markov random field template in an M×M lattice, with a complexity of order M2 logM, considering only global translations.
Proceedings ArticleDOI
Boosted dictionaries for image restoration based on sparse representations
TL;DR: This paper proposes to perform image restoration using an ensemble of weak dictionaries that incorporate prior knowledge about the form of linear corruption to result in a better performance compared to using a single dictionary obtained with a traditional alternating minimization approach.
Proceedings ArticleDOI
Vector quantization of transform components for speech coding at 1200 bps
TL;DR: A transform-based system is described for vector quantizing speech at and below 1200 b/s, using a fixed-dimension codebook to quantize low-resolution harmonic components of speech.
Proceedings ArticleDOI
Quantum Machine Learning for Audio Classification with Applications to Healthcare
TL;DR: A hybrid quantum neural network (QNN) model for COVID-19 cough classification is developed and the design of the QNN simulation architecture is described and results are given with and without quantum noise.
