Our primary objective is to show spatial-temporal alterations in human face recordings that are difficult or unfeasible to see with the bare eyes in an expressive manner. Eulerian Video Magnification [EVM] Is the technique developed that accepts a conventional video sequence as input and generates decomposition at spatial level and temporal filtering. Space is known as spatial. The term temporal relates to the passage of time. The resulting signal is subsequently amplified in order to disclose previously unnoticed data. We will be able to interpret the blood flow as it fills the face, as well as enhance and tell tiny motions, using our technology. Our method can be used in real time to depict events that occur at the user-selected temporal frequency.
