In idealized ray optics, where rays are assumed to converge to a point when perfectly focused, the shape of a defocus blur spot from a lens with a circular aperture is a hard-edged circle of light. A more general blur spot has soft edges due to diffraction and aberrations, [5] [6] and may be non-circular due to the aperture shape. Therefore ...
A miniature can also be simulated digitally, using an image editor to blur the top and bottom of the photograph, so that only the subject is sharp. With basic techniques, e.g., a tool such as Adobe Photoshop 's Lens Blur filter, [ 9 ] using sharpness gradients extending from the middle of the image to the top and bottom, the effect is quite ...
Blur kernel, downscaling operation and additive noise should be estimated for given input to achieve better results. Video super-resolution approaches tend to have more components than the image counterparts as they need to exploit the additional temporal dimension.
