“…The motion-blur angle estimation has been widely researched by domestic and foreign scholars, such as Dobeš [6] uses the power spectrum gradient to calculated motion-blur angle; Ji Hui [7] uses the image gradient combined with Fourier-Radon transform to estimate the motion-blur angle; Liang Zeng [12] utilizes the Hough transform to realize the motion-blur angle estimation; the more universal angle estimation methods are based on Radon transform [2]- [5] . However, the above algorithms are mainly for square image angle estimation.…”

For the angle distortion appeared in the motion-blur angle estimation of passive millimeter wave image, this paper proposes a distortion correction algorithm for obtaining the accurate motion-blur angle 1 . The correction algorithm can correct the distortion emerged in the traditional algorithm effectively and accurately. In this paper, we adopt the traditional Fourier-Radon algorithm to estimate the motion-blur angle; then the motion-blur angle distortion of rectangle image is corrected by utilizing the non-uniform quantization distortion mechanism; the mean square error value of corrected angle can keep lower than 1 which is greatly less than traditional error. Amount of experiments had been done to certificate the efficacy and robustness of our proposed approach.
