Effect of Bit Depth on Cloud Segmentation of Remote-Sensing Images
Remote Sensing, 2023 Due to the cloud coverage of remote-sensing images, the ground object information will be attenuated or even lost, and the texture and spectral information of the image will be changed at the same time.

Atmospheric Light Estimation Based Remote Sensing Image Dehazing
Remote Sensing, 2021 Remote sensing images are widely used in object detection and tracking, military security, and other computer vision tasks. However, remote sensing images are often degraded by suspended aerosol in the air, especially under poor weather conditions, such ...

Frequency-division-multiplexing based period-coded fringe pattern for reliable depth sensing
Journal of the European Optical Society-Rapid Publications, 2018 The fringe pattern can realize high-resolution and dense depth sensing. However, the phase ambiguity is a challenge in the fringe pattern. In this paper, one period-code pattern is embedded to the fringe pattern by the frequency-division-multiplexing ...

Depth Enhancement by Fusion for Passive and Active Sensing [PDF]
, 2012 This paper presents a general refinement procedure that enhances any given depth map obtained by passive or active sensing. Given a depth map, either estimated by triangulation methods or directly provided by the sensing system, and its corresponding 2-D image, we correct the depth values by separately treating regions with undesired effects such as ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.
