In this paper, a fast moving objects detection algorithm, based on motions estimation, is proposed. Our algorithm
consists of three main parts: Firstly, we use Enhanced Predictive Zonal Search(EPZS) method to match patches between
video frames, Then, moving objects contour information is extracted by applying Tree Structure Moving Compensation
(TSMC) technique into interesting patch subdivision and matching. Finally, we extract the patches of the target by the
statistics of motion vectors. By applying EPZS we can quickly detect the moving target and get its
information .Experiment shows that the algorithm can quickly and efficiently detected moving target and its contour
from adjacent frames. Compared with other algorithms, this algorithm has better usability and faster processing speed
while not be affected by the moving of camera.
