Abstract
A PSF cost function used for determining a PSF kernel () of at least a portion of an image () includes (i) a first fidelity term having a first direction derivative, (ii) a first fidelity term weight for the first fidelity term, (iii) a second fidelity term having a second direction derivative, and (iv) a second fidelity term weight for the second fidelity term. Another PSF cost function for determining a PSF kernel () includes (i) a first fidelity term with a first derivative in a dominant edge direction (d), and (ii) a second fidelity term having a second derivative in a perpendicular direction(p) to the dominant edge direction.
