A method of motion parameters estimation based on a single color motionblurred image was proposed. Firstly, the Fourier transform of the motion blur image was analyzed, thus the motion information for motion estimation in blurred image was obtained. Secondly, the three channels were treated separately for color image motion estimation to avoid the loss of information by image conversion. Aiming at the error of parameters getting stacked, the length and orientation of the motion were estimated respectively. The orientation of motion was estimated from the response of the Gabor filters which related with the spectrum of the blurred image. Additionally, the motion extent was obtained form the motion information of the blurred image by using cepstrum method. The experimental results show that this method is more precise for the motion parameters estimation based on one single blurred image.
