Real-time delivery of video over best-effort error-prone packet networks requires scalable erasure-resilient compression systems in order to 1) meet the users' requirements in terms of quality, resolution, and frame-rate; 2) dynamically adapt the rate to the available channel capacity; and 3) provide robustness to data losses, as retransmission is often(More)
Scalable wavelet-based video codecs using spatial-domain motion compensated temporal filtering (SDMCTF) require a quality-scalable motion vector codec (MVC) to support a large range of bit-rates with optimal compression efficiency. This letter introduces a new prediction-based architecture for quality-scalable motion vector coding that outperforms the(More)
Modern video coding applications require data transmission over variable-bandwidth wired and wireless network channels to a variety of terminals, possibly having different screen resolutions and available computing power. Scalable video coding technology is needed to optimally support these applications. Recently proposed wavelet-based video codecs(More)
Multimedia applications emerge on portable devices everywhere. These applications typically have a number of stringent requirements: (i) a high amount of computational power together with real-time performance and (ii) the flexibility to modify the application or the characteristics of the application at will. The performance requirements often drive the(More)
The availability of affordable 'recreational' camera traps has dramatically increased over the last decade. We present survey results which show that many conservation practitioners use cheaper 'recreational' units for research rather than more expensive 'professional' equipment. We present our perspective of using two popular models of 'recreational'(More)
Video coding techniques yielding state-of-the-art compression performance require large amount of computational resources, hence practical implementations, which target a broad market, often tend to trade-off coding efficiency and flexibility for reduced complexity. Scalable video coding instead, not only provides seamless adaptation to bit-rate variation,(More)
Scalable multiple-description (MD) coding allows for fine-grain rate adaptation as well as robust coding of the input source. In this paper, we present a new approach for scalable MD coding of images, which couples the multiresolution nature of the wavelet transform with the robustness and scalability features provided by embedded multiple-description(More)
