One of the major constraints in multiple description coding is the introduction of a variable amount of overhead, which is necessary to achieve a good perceived quality in case one or more descriptors are lost during transmission. In this reported work, data hiding techniques are exploited to optimise the trade-off between redundancy and quality in a two-descriptors scenario.
In this paper a method for providing additional information for error concealment during the transmission of a video file over an error-prone channel is presented. The transmission of the additional information is performed without increasing the bandwidth occupation, by hiding this information into the video itself at the encoder side. The considered transmission system is the DVB-H system. The performance...
In this paper, a new methodology for embedding data in a video sequence is presented. To guarantee the imperceptibility of the embedded data, we propose a method to select frame regions that are considered perceptually non relevant. For each frame a salience analysis is performed based on features that are relevant to the human vision system. In particular, the local contrast, the color and the areas...
