Effective Approach to Camera Zoom Detection Based on Visual Attention

摘要：

An effective approach based on geometric constraint of the motion vector field is proposed to detect camera zoom operation.The approach exploits the valid motion vectors to estimate the center of focus (COF) for zoom,and then calculates the average distance from the COF to valid motion vectors to identify zoom operation.To reduce the influence of object motion,Visual attention mechanism is employed to select valid motion vectors.Experimental results show that the proposed approach achieves a good performance.
