Haze can significantly reduce visibility and contrast of images captured outdoors, necessitating the enhancement of images. This degradation in image quality can adversely affect various applications, including autonomous driving, object detection, and surveillance, where poor visibility may lead to navigation errors and obscure crucial details. Existing dehazing techniques face several challenges: spatial methods tend to be computationally heavy, transform methods often fall short in quality, hybrid methods can be intricate and demanding, and deep learning methods require extensive datasets and computational power.

Objective: Cardiopulmonary bypass (CPB) initiated with high oxygen levels may expose cyanotic children to reoxygenation injury. The ideal method of initiation of bypass to prevent this phenomenon still remains largely unproven. This study tested the hypothesis that controlling oxygenation during initiation of CPB improves early postoperative outcomes.
