Super-resolution (SR) plays a crucial role in improving the image quality of magnetic resonance imaging (MRI). MRI produces multi-contrast images and can provide clear display soft tissues. However, current super-resolution methods only employ single contrast, or use simple fusion mechanism, ignoring rich relations among different contrasts, which are valuable for SR. In this work, we propose m...

Offline handwritten signature verification is one of the most prevalent and prominent biometric methods in many application fields. Siamese neural network, which can extract compare writers’ style features, proves to be efficient verifying offline signature. However, traditional network fails represent writing fully suffers from low performance when distribution positive negative samples unbala...

Routing is an important challenge in WSN due to the presence of hundreds or thousands of sensor nodes. Low Energy Adaptive Clustering Hierarchy (LEACH) is a hierarchical routing and data dissemination protocol. LEACH divides a network domain into several sub-domains that are called clusters. Non-uniformity of cluster distribution and CHs selection without considering the positions of other sens...
