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, ...

Depth sensing technologies provide machines with three-dimensional awareness by measuring the distance between a sensor and objects in a scene. Active methods such as time-of-flight (ToF) and ...

By borrowing a trick from tiny jumping spiders, Northwestern University engineers have developed an extremely ...

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 ...
