To prevent moving shadows being misclassified as moving objects or parts of moving objects, this paper presents an explicit method for detection of moving cast shadows on a dominating scene background. Those shadows are generated by objects moving between a light source and the background. Moving cast shadows cause a frame difference between two succeeding images of a monocular video image sequ...

Delivering timely status updates in a timeliness-critical communication system is of paramount importance to assist accurate and efficient decision making. Therefore, the topic analyzing Age Information (AoI) has aroused new research interest. This paper contributes results this area by systematically AoI two types Hybrid Automatic Repeat reQuest (HARQ) techniques that have been newly standardi...

Information extraction aims at extracting entities, relations, and so on, in text to support information retrieval systems. To extract information, researchers have considered multitask learning (ML) approaches. The conventional ML approach learns shared features across tasks, with the assumption that these capture sufficient task interactions learn expressive representations for classification...

We present an information-theoretic approach to the registration of images with directional information, especially for diffusion-weighted (DWIs), explicit optimization over scale. call it locally orderless directions (LORDs). focus on normalized mutual information as a robust similarity measure DWI. The framework is extension LOR-DWI density-based hierarchical scale-space model that varies and...

although explicit and implicit knowledge of language learners are essential to theoretical and pedagogical debates in second language acquisition (sla), little research has addressed the effects of instructional interventions on the two knowledge types (r. ellis, 2005).this study examined the relative effectiveness of explicit and implicit types of form-focused instruction (ffi) on the acquisit...

This paper presents an algorithm that converges to points that satisfy a first order necessary condition of weakly Pareto solutions of multiobjective optimization problems. Hints on how to include second order information are given. Preliminary numerical results are encouraging.

Animals are notoriously impulsive in common laboratory experiments, preferring smaller, sooner rewards to larger, delayed rewards even when this reduces average reward rates. By contrast, the same animals often engage in natural behaviors that require extreme patience, such as food caching, stalking prey, and traveling long distances to high-quality food sites. One possible explanation for this...
