Underwater Image Enhancement In Multi-Domain By Enhanced Wavelength Compensation And Image Dehazing

Abstract

Underwater images usually lack contrast and suffer from color distortion due to light beam scattering and attenuation. Light scattering is due to the presence of suspended particles in water in form of both organic and inorganic material which reflects and deflects the light in an unpredictable manner before it reaches the sensor and results in an image which is low in contrast. Water as a medium readily absorbs light, and moreover different wavelengths of light as absorbs at different rates.. In this era, underwater environment has attained more attention of scholars and scientists to observe the variation in it, due to human influence. In this article, we have proposed a new enhancement technique called Wavelength Compensation and Image Dehazing (WCID) in addition with Wavelet Discrete Transform (WDT).  In this proposed technique underwater images are enhanced in frequency as well as in time domain, to boost image quality in both the domains and produce better dehazed throughput. The proposed methodology is implemented over MATLAB platform.
