Extensive adoption of video surveillance, affecting many aspects of our daily lives, alarms the public about the increasing invasion into personal privacy. To address these concerns, many tools have been proposed for protection of personal privacy in image ...
The purpose of this review is to discuss the development and the state-of-the-art in dynamic testing methods and dynamic behaviour of rock materials in tension. Loading techniques commonly used for intermediate and high strain rate testing are pneumatic-hy ...
Subjective quality assessment is widely used to understand and to study human perception of multimedia quality and as a basis for developing objective metrics to automatically predict the quality of audiovisual presentations. There are several recognized i ...
Many classes of objects can now be successfully detected with statistical machine learning techniques. Faces, cars and pedestrians, have all been detected with low error rates by learning their appearance in a highly generic manner from extensive training ...
In one example, a device for retrieving multimedia data, the device comprising one or more processors configured to retrieve data of a first segment of a representation of multimedia content in accordance with data of a copy of a manifest file stored by th ...
When a stereo pair is formed from a decoded view and a synthesized view, it is unclear how the overall quality of the stereo pair should be assessed through objective quality metrics. In this paper, this problem is addressed considering a 3D video represen ...
This paper presents a new database containing high-definition audio and video recordings in a rather unconstrained video-conferencing-like environment. The database consists of recordings of people sitting around a table in two separate rooms communicating ...
