Proceedings ArticleDOI
Instant dehazing of images using polarization
TL;DR: This work analyzes the image formation process, taking into account polarization effects of atmospheric scattering, and invert the process to enable the removal of haze from images, and obtains a great improvement of scene contrast and correction of color.
Proceedings ArticleDOI
Blind Haze Separation
TL;DR: An approach for blindly recovering the parameter needed for separating the airlight from the measurements, thus recovering contrast, with neither user interaction nor existence of the sky in the frame is derived, which eases the interaction and conditions needed for image dehazing.
Journal ArticleDOI
Polarization-based vision through haze
TL;DR: An approach for easily removing the effects of haze from passively acquired images based on the fact that usually the natural illuminating light scattered by atmospheric particles (airlight) is partially polarized, which yields a range map of the scene which enables scene rendering as if imaged from different viewpoints.
Journal ArticleDOI
Recovery of underwater visibility and structure by polarization analysis
Yoav Y. Schechner,N. Karpel +1 more
TL;DR: A computer vision approach that removes degradation effects in underwater vision is presented, which inverts the image formation process for recovering good visibility in images of scenes and analyzes the noise sensitivity of the recovery.
Journal ArticleDOI
Active Polarization Descattering
Tali Treibitz,Yoav Y. Schechner +1 more
TL;DR: The paper presents an approach for recovering the object signal, which unifies and generalizes prior polarization-based methods, which had assumed exclusive polarization of either the backscatter and the object reflection of either of these components.
