Restoration of motion blurred image based on the digital radiography
Baolei Li · Optical Technique · 2007
In X-ray digital real-time imaging testing , the image is degraded by motion blur caused by the relative linear movement between object and image acquisition equipment .After the analysis of the theory on motion blur, discrete mathematical model of motion degeneration is established. The frequency characteristics of motion blur point spread function and the maximal average value of projection are used to determine motion direction. And rotating the Fourier transform image of motion blurred image ,the displacement of motion is determined by minimum of row projection method. Wiener filter is used to restore the motion blurred image, and a satisfactory result is gotten.
