Recently, the stereo imaging-based image enhancement approach has attracted increasing attention in the field of video analysis. This paper presents a dual camera-based stereo image defogging algorithm. Optical flow is first estimated from the stereo foggy image pair, and the initial disparity map is generated from the estimated optical flow. Next, an initial transmission map is generated using...

Reliable and exact assessment of visibility is essential for safe air traffic. In order to overcome the drawbacks of the currently subjective reports from human observers, we present an approach to automatically derive visibility measures by means of image processing. It first exploits image based estimation of the atmospheric transmission describing the portion of the light that is not scatter...

The mechanism by which pluripotent progenitors give rise to distinct classes of mature neurons in vertebrates is not well understood. To address this issue we undertook a genetic screen for mutations which affect the commitment and differentiation of catecholaminergic (CA) [dopaminergic (DA), noradrenergic (NA), and adrenergic] neurons in the zebrafish, Danio rerio. The identified mutations con...

Other than pneumonia, Long COVID is currently cited as a problem with COVID-19. Among them, brain fog particular problem. Brain fog, the name suggests, refers to state in which foggy, and it thought that there communication abnormality central nervous system, including fatigue. It has been pointed out this may be caused by cytokine storm, since lowers QOL (Quality of Life), countermeasures are ...

We compare conventional intensity imaging against different modes of polarimetric by evaluating the image contrast images taken in a controlled foggy environment. A small-scale fog chamber has been designed and constructed to create necessary division-of-focal-plane camera linear polarization linearly polarized light source used for performing experiments with light. In order evaluate modes, Mi...
