The availability and exponential growth in online media provides opportunities for understanding and responding to real world challenges. In this paper we investigate the photo quality assessment problem using a large volume of online images retrieved by Google Image Search. To effectively use the big data, we present new approaches that compute discriminative features from a group of relevant images...
Large amount of spectral wavebands of hyperspectral remote sensing data provide an abundant and valuable information for classification and detection, but at the same time, this will lead to redundancy and complexity of the data. In this paper, we proposed a subspace band section based RX algorithm for hyperspectral imagery (HSI) anomaly detection. Firstly, the adaptive subspace decomposition (ASD)...
Service descriptions via Web Services Description Language (WSDL) are necessary but not sufficient to service selection based on service trust. we need a means to collect nonfunctional information about services and use that information to assign dynamic trust levels to the service providers and implementations. In this paper, we briefly discuss the problem of service selection, given some correlation...
Synthetic evaluation of maintenance accessibility is important for finding the bug of maintenance accessibility design for complex equipment and improving the design project of complex equipment. But the present maintenance accessibility definition is fall short of the characteristic of complex equipment, so put forward the concept of maintenance accessibility and establish a synthetic evaluation...
In this paper we proposed a novel approach of blind channel equalizer for underwater multiple-input multiple-output orthogonal frequency diversity multiple (MIMO-OFDM) system. Convolutional encoder is applied on reference frequency bin and each block before entre the underwater MIMO-OFDM system. The transform imposed a correlation structure on the transmitted block, after every reference frequency...
