Physically inspired depth-from-defocus

作者:

Highlights:

• Novel forward operator preserving essential physical properties is pro-posed.

• No equifocal assumption is required.

• Joint handling of depth-from-defocus and denoising can improve the re-construction quality.

• Robustification leads to a better reconstruction at strong depth changes.

• Positivity constrained minimisation strategy increases the efficiency.
