Abstract

This study proposes an alternative effective sonar image enhancement algorithm. The method basically composes of two steps, including noise reduction and image sharpening. The sonar image is first de-noised using Wiener and median filters, and then it is enhanced using unsharp masking and histogram equalization. The proposed algorithm has been verified on many sonar images of different underwater structures, and shows its efficiency comparing to some well-known sonar noise reduction methods applying for sonar image data.

Key Words   
Sonar image processing; sonar noise reduction; local statistic filters
