A Review on DCP and CAP Based Dehazing Techniques-A Literature Survey

Angitha PV, Santhini K A


Dehazing is the process of removing atmospheric suspended particles like haze from images and it plays a dominant role in many image processing applications. The visibility of outdoor images is often degraded due to the presence of haze, fog, sandstorms, and so on. Poor visibility caused by atmospheric phenomena causes failure in image processing applications. Haze removal also known as dehazing refers to
different methods that aim to reduce or remove the image degradation that have occurred while the digital image was being obtained during inclement weather conditions. This paper mainly focuses on prior based dehazing techniques. Dark channel prior based dehazing and colour
attenuation prior based dehazing are the two existing prior based dehazing technique. This paper provides a comparison between various Dark Channel Prior based dehazing techniques, gives a brief idea about Colour Attenuation Prior based dehazing and also provides an idea about an advanced colour attenuation prior based dehazing technique.
