EXTENDED DEPTH-OF-FIELD CORRECTION USING RECONSTRUCTED IMAGE

A method includes obtaining 3D model of real-world environment; receiving image captured using camera, and pose information indicative of camera pose from which image is captured; utilising 3D model to generate reconstructed image from a perspective of camera pose; identifying group(s) of neighbouri...

Zusammenfassung:A method includes obtaining 3D model of real-world environment; receiving image captured using camera, and pose information indicative of camera pose from which image is captured; utilising 3D model to generate reconstructed image from a perspective of camera pose; identifying group(s) of neighbouring pixels in image that is/are out of focus; determining point spread function for group(s) of neighbouring pixels, based on correlation between group(s) of neighbouring pixels and corresponding group of neighbouring pixels in reconstructed image; and applying extended depth-of-field correction to group(s) of neighbouring pixels in image, by using point spread function.
