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...

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 ...

Recent advances in artificial intelligence make it progressively hard to distinguish between genuine and counterfeit media, especially images videos. One recent development is the rise of deepfake videos, based on manipulating videos using advanced machine learning techniques. This involves replacing face an individual from a source video with second person, destination video. idea becoming ref...

Discerning subtle abnormal movements is often critical in making the correct neurologic diagnosis. However, many telltale movements are hardly visible to the nonspecialist’s eye. Using Eulerian video magnification (EVM), which applies a spatial and temporal filtering algorithm to amplify movements digitally on (real-time) video, we present 3 neurologic patients in whom the diagnosis became obvi...
