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 ...

Estimating how far away every pixel in a photograph truly lies, in meters rather than merely in relative order, has long been ...

Lighter images represent pre-2020 models with limited data and images to use(sub-one million parameters); darker images post-2020 represent models using over a million parameters with the darkest ...

A simple pattern of black-and-white stripes could cause an autonomous vehicle or robot to misjudge how far away an obstacle is, potentially triggering an unexpected maneuver or even a collision, ...

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 ...
