Eulerian Video Magnification and Analysis

Eulerian Video Magnification and Analysis

We present Eulerian Video Magnification, a computational technique for visualizing subtle color and motion variations in ordinary videos by making the variations larger.

Technical Perspective: Mapping the Universe

"HACC: Extreme Scaling and Performance Across Diverse Architectures" describes the Hardware/Hybrid Accelerated Cosmology Code (HACC) framework, which uses a novel algorithmic structure to map code onto multiple supercomputer …

Technical Perspective: Magnifying Motions the Right Way

"Eulerian Video Magnification and Analysis" demonstrates that phase differences at a given frequency band, due to subtle motions in a video, can be independently amplified and added back into the original signal.

HACC: Extreme Scaling and Performance Across Diverse Architectures

HACC

In this Research Highlight, we demonstrate the success of HACC on two very different machines, the CPU/GPU system Titan and the BG/Q systems Sequoia and Mira, attaining very high levels of scalable performance.
