Abstract This chapter describes a DeepFake detection framework based on physiological measurement. In particular, we consider information related to the heart rate using remote photoplethysmography (rPPG). rPPG methods analyze video sequences looking for subtle color changes in human skin, revealing presence of blood under tissues. explores what extent is useful videos. We recent fake detector ...

Background: The accuracy of speckle-tracking echocardiography (STE) depends on temporal resolution. goal this study was to demonstrate the feasibility relatively high frame rate (rHi-FR) (~200 fps) for STE. Methods: In prospective study, echocardiographic images were acquired using clinical scanners patients with normal left ventricular systolic function rHi-FR and conventional (Reg-FR) (~50 FP...

According to investigating impact of complexity of stereoscopic frame pairs on stereoscopic video coding and transmission, a new rate control algorithm is presented. The proposed rate control algorithm is performed on three levels: stereoscopic group of pictures (SGOP) level, stereoscopic frame (SFrame) level and frame level. A temporal-spatial frame complexity model is firstly established, in ...

Virtual environments involve the user in an interactive three-dimensional computer generated environment. The methods of interaction typically involve direct manipulation of virtual objects via three-dimensional trackers. The tracking signal may be degraded in various ways, impacting the ability of the user to perform various tasks. This presentation will address the impact of two types of degr...
