本文根据柴西南具有相对平缓沉积背景、三大物源控制沉积相带和后期构造运动剧烈的特点,通过建立等时层序地层格架,分析各时期的主要物源和沉积相展布,研究岩性圈闭形成的构造沉积背景,明确岩性圈闭发育的主要目的层段和有利勘探区带。
5) Background/Non-Background Classification
背景/非背景分类
1.
In the AVS-based video surveillance system,the AVS coding and decoding standards are combined with other processing techniques,such as background/non-background classification,face detection and recognition,and two-level indexing structure to automatically identify the persons who appeared in the surveillance videos.
该系统结合AVS视频编解码、背景/非背景分类、人脸检测与识别等技术,可输入文本、图片和视频段对出现在监控视频中的人物进行身份的自动识别,并引入两级索引结构以达到快速检索的目的,在数字监控、门禁控制以及身份识别等方面有一定的应用价值。
6) ancient deposition setting
