Fractal-driven distortion of resting state functional networks in fMRI: a simulation study
Wonsang You, Jörg Stadler
Fractals are self-similar and scale-invariant patterns found ubiquitously in nature. A lot of evidences implying fractal properties such as 1/f power spectrums have been also obser…
Fractal analysis of resting state functional connectivity of the brain
Wonsang You, Sophie Achard, Jörg Stadler +2
A variety of resting state neuroimaging data tend to exhibit fractal behavior where its power spectrum follows power-law scaling. Resting state functional connectivity is significa…
Fractal-based Correlation Analysis for Resting State Functional Connectivity of the Rat Brain in Functional MRI
Wonsang You, Joerg Stadler
The most studies on functional connectivity have been done by analyzing the brain's hemodynamic response to a stimulation. On the other hand, the low-frequency spontaneous fluctuat…
A Proof on Asymptotics of Wavelet Variance of a Long Memory Process by Using Taylor Expansion
Wonsang You, Wojciech Kordecki
A long memory process has self-similarity or scale-invariant properties in low frequencies. We prove that the log of the scale-dependent wavelet variance for a long memory process…
Real-time detection and tracking of multiple objects with partial decoding in H.264/AVC bitstream domain
Wonsang You, M. S. Houari Sabirin, Munchurl Kim
In this paper, we show that we can apply probabilistic spatiotemporal macroblock filtering (PSMF) and partial decoding processes to effectively detect and track multiple objects in…
