Real-Time Billboard Substitution in a Video Stream
We present a system that accepts as input a continuous stream of TV broadcast images from sports events. The system automatically detects a predetermined billboard in the scene, and replaces it with a user defined pattern, with no cooperation from the billboards or camera operators. The replacement is performed seamlessly so that a viewer should not be able to detect the substitution. This allo...
متن کاملTowards Real-Time Stream Quality Prediction: Predicting Video Stream Quality from Partial Stream Information
While mechanisms exist to evaluate the user-perceived quality of video streamed over computer networks, there are few good mechanisms to do so in real time. In this paper, we evaluate the feasibility of predicting the stream quality of partial portions of a video stream based on either complete or incomplete information from previously rated streams. Using stream state information collected fro...
متن کاملNear Real-Time 3D Reconstruction from InIm Video Stream
An efficient hardware architecture for the acceleration of an integrated 3D reconstruction method is presented, targeting demanding dynamic Integral Imaging applications. It exploits parallel processing and features minimized memory operations by implementing an extended-access memory scheme. Its reduced data throughput, thanks to optimized data utilization, makes it suitable for single FPGA de...
متن کاملReal-time watermarking algorithm of H.264/AVC video stream
Due to the extensive use of digital media applications, digital productions are easily copied and manipulated. Therefore, multimedia security and copyright protection is becoming important. Digital watermarking is an excellent tool to ensure security and protection of multimedia data by embedding some information into the digital production. For real time applications, such as Internet Protocol...
متن کاملAdaptive Forward Error Correction for Real-time Internet Video
Real-time video communication over packet networks is attracting a lot of attention for applications such as distributed collaborative work, teleteaching and telemedicine. Due to its sensitivity to delay, real-time communication is usually based on unreliable transport protocols, like UDP, since retransmission of lost packets is considered to take too long time. Instead of retransmissions forwa...
