Method for de-blurring images of moving objects
First Claim
Patent Images
1. A method for deblurring images of a scene that includes a moving object, the method comprising, obtaining a blurred primary image I of the scene that includes the moving object;
- obtaining a point spread function S that models the movement of the moving object;
obtaining a background image B of the scene;
obtaining a shape of the moving object;
computing a mask M from the shape of the moving object and the point spread function;
applying the mask to the background image B to isolate a static background component not associated with the moving object;
isolating a moving object component of the primary image I;
deblurring the moving object component by image deconvolution with the point spread function; and
superimposing the deblurred moving object component and a background component to obtain a deblurred primary image of the scene.

Abstract
Systems and methods for providing methods are provided for deblurring images, which are blurred due to the movement of objects in the imaged scene. The systems and methods involve separating a moving object component from a static or background component of a primary image. The moving object component is deblurred using suitable image processing algorithms, and then superimposed on the static or background component to obtain a deblurred primary image.

10. An image processor for deblurring a primary image I of a scene captured with a primary detector, wherein the primary image I is blurred due to the movement of an object in the scene, the processor comprising:
-
a first arrangement for separating a moving object component from the primary image I;
a second arrangement for deblurring the moving object component by image deconvolution; and
a third arrangement for superimposing the deblurred moving object component on a background image of the scene to obtain a deblurred primary image of the scene. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
