Depth estimation and shape from focus (SFF) techniques remain at the forefront of computer vision research, addressing the challenge of recovering three-dimensional structural information from ...

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 ...

Results of Turbid Underwater 3D Polarization Imaging. (a) Polarization binocular underwater robot and marine experimental scene. (b) Binocular imaging restoration results, depth estimation results and ...

LVIRA™ is the first commercially available multimodal snapshot spectral imaging and light field polarization imager. LVIRA™ simultaneously captures spectral, light field and polarization information ...

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, ...
