| 摘 要： | 为有效识别视频情感的内容,基于未确知数学理论,建立了视频低层特征和高层认知情感之间的联系,提出了一种基于未确知测度的新算法.首先,选取能反映情感变化的场景亮度、镜头切变率和色调效能作为视频情感低层特征,介绍了每种情感特征的数据提取方法,并由此构建了视频情感特征向量.其次,构造了视频场景的未确知对象空间和指标空间,并给出...

| Abstract: | Based on unascertained measure,a novel algorithm for affective content recognition of the video is proposed by establishing the relationship between low-level video features and high-level cognitive emotion about video scene.First,the scene brightness,shot cut rate and color efficacy in a video scene are selected as the low-level video features for their special characteristics that can be used to better distinguish different types of human emotion.Meanwhile,the methods of data extraction from each emotion ... |
