Image registration is used widely in applications for mapping one image to another. Existing image registration methods are either feature-based or intensity-based. Feature-based methods first extract relevant image features and then find the geometrical transformation that best matches the two corresponding sets of features extracted from the two images.(More)
Image registration (IR) aims to geometrically match one image to another. It is extensively used in many imaging applications. Among many existing IR methods, one widely used group of methods are feature-based. By a feature-based method, a number of relevant image features are first extracted from the two images, respectively, and then a geometric matching(More)
Image registration aims to map one image to another of a same scene. It is a fundamental task in many imaging applications. Most existing image registration methods assume that the mapping transformation has a parametric form or satisfies certain regularity conditions (e.g., it is a smooth function with continuous first or higher order derivatives). They(More)

We consider incorporating topic information into the sequence-to-sequence framework to generate informative and interesting responses for chatbots. To this end, we propose a topic aware sequence-to-sequence (TA-Seq2Seq) model. The model utilizes topics to simulate prior knowledge of human that guides them to form informative and interesting responses in(More)
In this paper, a component library model based on the four-layer architecture is presented. The four-layer architecture includes framework layer, component layer, leaf-class layer and leaf-function (leaf-method) layer. The component library is hierarchically constructed. The component features in different layers and the relationship among components are(More)

lifetime) and at the very end of the lifetime (about 80–95%) (11). Other potential magnetic techniques for detecting fatigue damage include measurements of the Barkhausen effect (BE) (13, 14) and magneto-acoustic emission (MAE) (15) signals. BE and MAE signals originate from discontinuous magnetisation processes occurring during the hysteresis cycle. It has(More)
We study multi-turn response generation in chatbots where a response is generated according to a conversation context. Existing work has modeled the hierarchy of the context, but does not pay enough attention to the fact that words and utterances in the context are differentially important. As a result, they may lose important information in context and(More)
