In video streaming there is a problem of packet-loss during signal transmission. Because of this fact the quality of the video could be highly distorted. Different error concealment schemes are used at the decoder side or even after decoding process to fight this. In this paper a new spatio-temporal error concealment scheme with low computational complexity and high visual and objective quality...

An efficient error concealment algorithm for multi-view video sequences is proposed in this work. First, we develop three concealment modes: temporal bilateral error concealment (TBEC), inter-view bilateral error concealment (IBEC), and multi-hypothesis error concealment (MHEC). TBEC and IBEC, respectively, exploit intra-view and inter-view correlations in multi-view video sequences to reconstr...

Consisting of two cross-sectional studies, the present study investigated whether psychological flexibility mediates the relations between self-concealment and negative psychological outcomes. Study 1 examined whether psychological flexibility mediates the relations between self-concealment and emotional distress in stressful interpersonal situations. In addition to replicating results of Study...

In this paper, we propose content-adaptive refined error concealment schemes for video transmission over packet lossy networks. The proposed spatial and temporal error concealment algorithms improve the reconstructed video quality at the common loss rates encountered on the networks. To reduce the computational complexity, the proposed schemes make use of the existing information of Intra predi...

In an error-prone transmission environment, error concealment is an effective technique to reconstruct the damaged visual content. Due to large variations of image characteristics, different concealment approaches are necessary to accommodate the different nature of the lost image content. In this paper, we address this issue and propose using classification to integrate the state-of-theart err...

Introduction: Electrophysiological studies have demonstrated a relationship between aging and atrioventricular (AV) nodal conduction and refractoriness. The aim of the present study was to determine the effects of nodal aging on dynamic AV nodal field potential recording during atrial fibrillation (AF) in rabbit. Methods: Two groups of male New Zealand rabbits (neonatal 2-week-olds and adult...

The plant community within which flower evolution takes place has largely been ignored. We develop two models for the evolution of nectar concealment when flowers are visited by legitimate pollinators and flower parasites. When there is a single plant species, no level of nectar concealment is evolutionarily stable: any population can be invaded by mutants exhibiting a higher level of nectar co...

Small herbivores face risks of predation while foraging and are often forced to trade off food quality for safety. Life history, behaviour, and habitat of predator and prey can influence these trade-offs. We compared how two sympatric rabbits (pygmy rabbit, Brachylagus idahoensis; mountain cottontail, Sylvilagus nuttallii) that differ in size, use of burrows, and habitat specialization in the s...

Digital TV signals being transmitted over errorprone channels often suffer from lost macro blocks or slices. In literature, a wide range of approaches for error concealment is described exploiting spatial and/or temporal references. In 2008, we introduced a new paradigm for error concealment utilizing several representations of a particular TV signal which are available in multi-broadcast-recep...
