Abstract

提供了一种在线视频浓缩装置、系统及方法。该方法包括：步骤1，获取一帧图像；步骤2，分割该图像的前景图像和背景图像，针对分割出的前景图像执行步骤3，针对分割出的背景图像执行步骤5;步骤3，从该前景图像中提取出运动物体；步骤4，循环执行步骤1至步骤3，累积从各帧前景图像中分别提取出的运动物体，形成运动物体序列，直到循环次数达到预定值；步骤5，循环执行步骤1至步骤2，累积各帧图像的背景图像，从中提取特定n帧背景图像作为主背景序列，直到循环次数达到预定值；步骤6，将该主背景序列与该运动物体序列进行拼接，形成浓缩视频。该方法利用在线浓缩方式，缩短了浓缩视频长度，尽量保留视频中的运动物体信息。
