Disclosed are systems and methods for detecting moving objects. A computer-implemented method for detecting moving objects comprises obtaining a streaming video captured by a camera; extracting an input image sequence including a series of images from the streaming video; tracking point features and maintaining a set of point trajectories for at least one of the series of images; measuring a likelihood for each point trajectory to determine whether it belongs to a moving object using constraints from multi-view geometry; and determining a conditional random field (CRF) on an entire frame to obtain a moving object segmentation. 本发明涉及采用单个相机检测运动物体的方法和系统。具体地，种检测运动物体的计算机执行方法包括获取由相机捕捉的串流影像；从串流影像中提取包括系列图像的输入图像序列；对于系列图像中的至少个追踪点轨迹并且保留点轨迹的集合；使用来自多视图几何图形的约束测量每个点轨迹的似然性以确定是否其属于运动物体；并且确定整个帧上的条件随机域(CRF)以获取运动物体分割。
