AdaFNIO: Adaptive Fourier Neural Interpolation Operator for video frame interpolation

, 2022
We present, AdaFNIO - Adaptive Fourier Neural Interpolation Operator, a neural operator-based architecture to perform video frame interpolation. Current deep learning based methods rely on local convolutions for feature learning and suffer from not being scale-invariant, thus requiring training data to be augmented through random flipping and re ...

Membrane Vesicles from Lacticaseibacillus Casei BL23 Exhibit Antimicrobial Activity Against Escherichia coli and Immunostimulatory Effects on Human Peripheral Blood Mononuclear Cells

Advanced Healthcare Materials, EarlyView.
Membrane vesicles derived from the probiotic Lacticaseibacillus casei BL23 demonstrate antimicrobial properties against Escherichia coli and a potential biological effect in improving the overall survival of C. elegans infected with Pseudomonas aeruginosa. These vesicles stimulated immune responses in primary cells without causing toxicity. Our results

Local Visual Microphones: Improved Sound Extraction from Silent Video

, 2017
Sound waves cause small vibrations in nearby objects. A few techniques exist in the literature that can extract sound from video. In this paper we study local vibration patterns at different image locations.
