A Survey – Audio and Video Synchronization
The audio and video Synchronization is extremely necessary. The synchronization loss between image and sound continues to disturb observers and irritate telecasters. The demand is to assure synchronization without adjusting content at the same time as still retaining price low. The objective of the synchronization is to line up both the audio and video signals that are processed individually. T...
متن کاملAdaptation and Synchronization in Bandwidth-Constrained Internet Video and Audio
Systems for the real-time transmission of video and audio on low-bandwidth lines must account for the limited bandwidth available, the bandwidth variance, packet loss rates, as well as CPU load. Vosaic, short for Video Mosaic, integrates real-time continuous media within standard Web pages, and handles the issues of transmitting continuous media with the Video Datagram Protocol (VDP). VDP dynam...
متن کاملObject Localization by Joint Audio-Video Signal Processing
There are many di erent approaches either for the localization of sound sources or for tracking of visible objects in image sequences. However, most applications use only one modality, that is, they process only audio or video information for object localization. In this paper we introduce a method for the estimation of object positions based on joint audio-video information. The key technique ...
متن کاملFaceSync: A Linear Operator for Measuring Synchronization of Video Facial Images and Audio Tracks
FaceSync is an optimal linear algorithm that finds the degree of synchronization between the audio and image recordings of a human speaker. Using canonical correlation, it finds the best direction to combine all the audio and image data, projecting them onto a single axis. FaceSync uses Pearson's correlation to measure the degree of synchronization between the audio and image data. We derive th...
