Modified Adaptive Filtering and Equalization Based Wavelength Adjustment and De-Burring in Underwater Images

Underwater environments generally cause color cast or color scatter while photography. color scatter is due to haze effects appearing when light reflected from thing which absorbed or may be scattered several times by particles of water. Thesis work present a novel procedure for which is a special integration for various available techniques also it has new approach in order to image stretching and image equalisation. Proposed procedure enhances shallow ocean optical images or videos using stretching cum equalizing cum median filter and also as per wavelength properties. Our key contributions are proposed include a novel shallow water imaging model that compensates in order to attenuation discrepancy along propagation path and an effective underwater scene enhancement scheme recovered images are characterized by a reduced noised level, better exposure for dark regions, and global contrast where finest details and edges are enhanced significantly.
