For multihypothesis-based compressed video sensing schemes, the low accuracy of weight prediction and degradation of recovery quality for high-motion videos are open challenges. To solve this problem, this paper proposes a new multihypothesis prediction scheme. To efficiently get high-quality hypoth…
A mirrored array configuration, which consists of an ordinary linear array and a reflector, is proposed. The mirrored arrays can provide composable degrees of freedom (DOF) for array processing by combined measurements with the help of mechanical adjustment (e.g., movement or rotation). This composa…
In this paper, a new method to classify the animal sound signals that are overlapped in time-frequency domain based on sparse representation is proposed. In order to obtain a discriminant sparse representation of overlapped animal sound signals, a novel dictionary atom discriminant factor is introdu…
Recent works have shown that hierarchical models lead to significant improvement in human activity recognition, which can not only enhance descriptive capability, but also improve discriminative power. However, most existing methods exploit just one of the two advantages. In this paper, a new hierar…
