The proposed method takes as input the focal stack and camera settings, and establishes a cost volume based on a lens defocus model. This design enables depth estimation with different camera settings ...

One of the most striking differences between your iPhone and a large camera like a DSLR is the way the two cameras focus and control depth of field. In a DSLR, depth of field is easy to manage by ...

In photography, depth of field refers to how much of a three-dimensional space the camera can focus on at once. A shallow depth of field, for example, would keep the subject sharp but blur out much of ...

Researchers have developed a new method for flexibly creating various needle-shaped laser beams. These long, narrow beams can be used to improve optical coherence tomography (OCT), a noninvasive and ...

Please provide your email address to receive an email when new articles are posted on . For all people, pupil size has an important role in balancing incoming light with depth of field to optimize ...

Photos can pop when one area is in sharp focus and the other blurry, providing the impression of depth in a two-dimensional image that matches how our eyes focus on objects, even though we don’t ...

In an image, estimating the distance between objects and the camera by using the blur in the images as clue, also known as depth from focus/defocus, is essential in computer vision. However, ...
