In a legal process, a manipulated video can provide the necessary elements to accuse an innocent person of a crime or to exempt a guilty person from criminal acts. Therefore, it is essential to create robust forensic methods, which will strengthen the justice administration systems and thus make...
[ 1 ]. It is used in a variety of fields, including security systems, digital video processing, and so on. When there are hundreds of songs, it is difficult for music listeners to manually create and segregate the playlist. The system's overall concept is to determine the song's mood ...
The algorithm works by scanning a conventional video of an infant to detect certain poses and movement patterns. The algorithm uses a “pose estimation method” to generate a stick-man depiction of the infant. These movement patterns can then be analyzed to detect normal or unusual movements. Ch...
In this study, we present a new method for remote detection of mental stress via webcam. The system is based on remote Photoplethysmograph (rPPG) obtained from face video frames of heart rate, breathing rate, and pulse rate variability (PRV). The experiment collected pulse wave data from ...
For video data, we further introduce a weighted loss to emphasize the importance of the center frame and its near neighbors because it is unfair to treat all frames in a 3D convolution frame cuboid equally. To understand the effectiveness of our proposed method, we test on video datasets UCSD...
Instead, the bulk of related works in a broader sense comes from video annotation and key frame detection. 2.1. Video Annotation Methods The process of ground truth annotation has become a fundamental task in the development of machine learning based computer vision applications. Due to its time-...
Tributyltin (TBTO, CAS 56-35-9), formaldehyde (HCHO, CAS 50-00-0), mercury chloride (HgCl2, CAS 7487-94-7) and lindane (γ-BHC, CAS 58-89-9) were obtained from Sigma-Aldrich (St. Louis, MI, USA). 2.3. The Video-Tracking System and Exposure Experiments The swimming behaviour was...
