Thermal and illumination effects on a PbI <sub/>2</sub> nanoplate and its transformation to CH <sub/>3</sub> NH <sub/>3</sub> PbI <sub/>3</sub> perovskite
摘要： Movie highlights are composed of video segments that induce a steady increase of the audience’s excitement. Automatic movie highlights’ extraction plays an important role in content analysis, ranking, indexing, and trailer production. To address this challenging problem, previous work suggested a direct mapping from low-level features to high-level perceptual categories. However, they only considered the highlight as intense scenes, like fighting, shooting, and explosions. Many hidden highlights are ignored because their low-level features’ values are too low. Driven by cognitive psychology analysis, combined top-down and bottom-up processing is utilized to derive the proposed two-way excitement model. Under the criteria of global sensitivity and local abnormality, middle-level features are extracted in excitement modeling to bridge the gap between the feature space and the high-level perceptual space. To validate the proposed approach, a group of well-known movies covering several typical types is employed. Quantitative assessment using the determined excitement levels has indicated that the proposed method produces promising results in movie highlights’ extraction, even if the response in the low-level audio-visual feature space is low.

摘要： Touch plays a prominent role in communicating emotions and intensifying interpersonal communication. Affective haptics is an emerging ?eld, which focuses on the analysis, design, and evaluation of systems that can capture, process, or display emotions through the sense of touch. The objective of this paper is to present an overview of the recent achievements in affective haptics and to discuss how the sense of touch can elicit or in?uence human emotions. We ?rst introduce a de?nition to the term affective haptics and describe its multidisciplinary nature—as a ?eld that integrates ideas from affective computing, haptic technology, and user experience. Second, we provide a thorough discussion about the effectiveness of using the haptic channel to communicate affective information through direct and mediated means. Third, we present a variety of applications in the area ranging from interhuman social interaction systems to human robot interaction applications. Finally, we discuss some of the key ?ndings discerned from the various surveyed papers, and present some of the challenges and trends in this ?eld. We extract the following conclusions pertaining to affective haptics: 1) haptic stimulation can be successfully used to achieve a higher level of emotional immersion during media consumption or emotional telepresence; 2) existing research has demonstrated that haptics is effective in communicating valence and arousal, and the emotions of happiness, sadness, anger and fear, and less focus have been given to the communication of disgust and surprise; 3) the haptic-based affect detection remains an understudied topic, whereas the haptic-based affect display is a well-established subject; and 4) the interpretation of the haptic stimulation by human beings is highly contextual.
