Moving object detection by combining SIFT and differential multiplication
For the difficulty of moving object detection by a moved camera
a method for detecting dynamic background caused by camera motion was proposed by combining a Scale Invariant Feature Transform(SIFT) and a differential multiplication. Firstly
the image registration based on SIFT features was applied to calculate transformation parameters
including translation factors
rotation angles and scaling coefficients
and to provide a robust matching for realizing the motion compensation precisely. Then
the object segmentation based on the differential multiplication was introduced to detect moving objects accurately. Finally
the experiments on the video sequences were performed to verify the robustness and validity of the method.Experiments show that instead of 6 or more frames
4 frames are enough for the differential multiplication in practical applications. The detection method is robust and denoising in dynamic scenes and has good adaptability to changing illumination
occlusion and camera movement.
