Identification of Blurred Extent with Rotation Motion Blurred Image

Based on the models of image motion blurring and restoring, the element of image blurring caused by rotation motion is analyzed. Three widely used methods for the identification of blurred extent from the rectilinear motion blurred images, Fourier transform, error-parameter curve, and autocorrelation, are introduced in rotation motion blurred image analysis. The feasibility and effectiveness of the above methods´ introduction are demonstrated. The computer simulation results prove that the autocorrelation algorithm is effective to identify the blurred extent of the rotation motion blurred images.
