Definition
The process of descattering refers to enhancing images acquired in scattering media.
Background
Imaging in scattering media poses special concerns for computer vision methods. Examples for such media include haze or bad weather, water, blood, and body tissue. Light propagating in such media is scattered and attenuated. When imaging, some light from the source is scattered back from the medium toward the camera, before ever reaching the object. This light is an additive radiance component in the image that veils the object. In air, this additive component is often termed airlight, and in water and tissue, it is termed veiling-light or backscatter (this term will be used further on). The backscatter hampers visibility by reducing contrast and signal-to-noise ratio (SNR) in the images [1]. The backscatter increases the measured radiance, which increases the photon noise, without increasing the signal...
