A Review: Eulerian Video Motion Magnification
Thispaper reviews computational techniques to efficiently represent, analyse and visualise both shortterm and long-term temporal variation in video and image sequences. This paper reveals temporal variation in videos that are imperceptible to the naked eye. The method takes a standard video sequence as an input, and applies spatial decomposition, followed by temporal filtering to the frames whi...
متن کاملEulerian Video Acceleration Magnification
The ability to amplify or reduce subtle image changesover time is useful in contexts such as video editing, medicalvideo analysis, product quality control and sports. In thesecontexts there is often large motion present which severelydistorts current video amplification methods that magnifychange linearly. In this work we propose a method to copewith large motions while ...
متن کاملNoninvasive Free Flap Monitoring Using Eulerian Video Magnification.
Eulerian Video Magnification (EVM) can enhance subtle changes in videos to reveal what was once invisible to the naked eye. In this proof of concept study, we investigated using EVM as a novel form of free flap monitoring. Free flaps with skin paddles were filmed in the operating room with manipulation of their pedicles. In a representative 77-year-old female who received a latissimus dorsi-ser...
متن کاملA New Wavelet Based Spatio-temporal Method for Magnification of Subtle Motions in Video
Video magnification is a computational procedure to reveal subtle variations during video frames that are invisible to the naked eye. A new spatio-temporal method which makes use of connectivity based mapping of the wavelet sub-bands is introduced here for exaggerating of small motions during video frames. In this method, firstly the wavelet transformed frames are mapped to connectivity space a...
متن کاملCan we see photosynthesis? Magnifying the tiny color changes of plant green leaves using Eulerian video magnification
Plant aliveness is proven through laboratory experiments and special scientific instruments. In this paper, we aim to detect the degree of animation of plants based on the magnification of the small color changes in the plant’s green leaves using the Eulerian video magnification. Capturing the video under a controlled environment, e.g., using a tripod and direct current (DC) light sources, redu...
