Sparseness Meets Deepness: 3D Human Pose Estimation from Monocular Video [PDF]

open access: yesComputer Vision and Pattern Recognition, 2015
This paper addresses the challenge of 3D full-body human pose estimation from a monocular image sequence. Here, two cases are considered: (i) the image locations of the human joints are provided and (ii) the image locations of joints are unknown.

Deterministic sparse FFT for M-sparse vectors [PDF]

open access: yesNumerical Algorithms, 2017
In this interesting paper, the authors present a new deterministic sparse (inverse) fast Fourier transform (FFT), where the resulting vector \(\mathbf x \in {\mathbb C}^N\) with \(N = 2^J\) is \(M\)-sparse, i.e., \(\mathbf x\) contains only \(M\) nonzero components. This new algorithm which generalizes the sparse FFT of \textit{G. Plonka} and \textit{K.

Sparse Sparse Bundle Adjustment [PDF]

open access: yesProcedings of the British Machine Vision Conference 2010, 2010
Sparse Bundle Adjustment (SBA) is a method for simultaneously optimizing a set of camera poses and visible points. It exploits the sparse primary structure of the problem, where connections exist just between points and cameras. In this paper, we implement an efficient version of SBA for systems where the secondary structure (relations among cameras ...

Task-Related Synaptic Changes Localized to Small Neuronal Population in Recurrent Neural Network Cortical Models

open access: yesFrontiers in Computational Neuroscience, 2018
Humans have flexible control over cognitive functions depending on the context. Several studies suggest that the prefrontal cortex (PFC) controls this cognitive flexibility, but the detailed underlying mechanisms remain unclear.

Sparse Transcription [PDF]

open access: yesComputational Linguistics, 2021
AbstractThe transcription bottleneck is often cited as a major obstacle for efforts to document the world’s endangered languages and supply them with language technologies. One solution is to extend methods from automatic speech recognition and machine translation, and recruit linguists to provide narrow phonetic transcriptions and sentence-aligned ...

Learning the Hierarchical Parts of Objects by Deep Non-Smooth Nonnegative Matrix Factorization

open access: yesIEEE Access, 2018
Nonsmooth nonnegative matrix factorization (nsNMF) is capable of producing more localized, less overlapped feature representations than other variants of NMF while keeping satisfactory fit to data. However, nsNMF as well as other existing NMF methods are

Reverberation Suppression Method for Active Sonar Systems Using Non-Negative Matrix Factorization With Pre-Trained Frequency Basis Matrix

open access: yesIEEE Access, 2021
In active sonar systems, detection always suffers from reverberation interference from multiple scatterers in oceanic environments; therefore, numerous studies have been conducted on reverberation suppression.
