Abstract:
Due to the medium’s scattering and absorption, underwater image captures
are prone to colour distortion, detail loss, and contrast reduction. The arti cle provides a technique for enhancing underwater photography quality that
doesn’t require any special software,more than the native single image.The
three techniques are used here for enhancing underwater image include Trans mission map, an enhanced white-balancing method,and multiscale image fu sion method .A guidance filter is adapted to refine the estimated transmis sion map depth.The suggested technique increases the underwater object’s
visibility and restores quality image. The white balancing method is to re move the color distoration from underwater image,it uses 5 channel com pensated approaches,these 5 channels are white balanced using gray world
algorithm.In white-balancing method, the Underwater Colour Image Quality
Evaluation (UCIQE) and the Underwater Image Quality Measure (UIQM)
are added together to determine the best color-compensated method. The
gamma-correction process is used to create numerous underexposure versions
from a single underwater images. Then, in the well-known multi-scale fus ing approach , suggest blending ”chrominance”,”luminance”,and ”saliency”
as three weights. The visual quality of an image is predominantly influenced
by these weights, aiming to generate a fusion result with improved visual
appeal.Through validation with a wide range of qualitative and quantitative
evaluations ,has been able to demonstrate that images enhanced by our strat egy have superior visual quality than other cutting-edge underwater dehazing
procedures.
