Replacement of Missing Visual Data Pockets with Prediction in Visual Control of Robots

In this article, teleoperation over Internet is considered. A significant problem in teleoperations occurs if data is lost or late. This can lead to the fatal error in command decisions made by operator. Since operator must decide based on data on the client side of the link, modifications presented here are on the client side of the teleoperation system. Visual data was of particular concern. Visual data can be lost in transmission over the Internet and operator can be confused or disable in making decision of robot movement. We proposed replacement of missing data with wavelet predicted image
