As a result of recent progress in networks and hardware, digital video data are increasing significantly. Audio in the video carries abundant semantic message. To understand audio semantic, an audio track semantic similarity computing approach for video semantic content analysis is proposed in this paper. In order to provide a uniform way to make different audio effects to compute quantify similarity,...
In satellite remote-sensing detection, cloud as an interference plays a negative role in data retrieval. A new method rooting on atmospheric radiation characteristics of cloud layer, in this paper, presents a sort of solution that single-band brightness variance ratio be used to detect the relative intensity of cloud clutter so as to delineate cloud field rapidly and exactly and, enable cloud elimination...
