Realization and Simulation of an Underwater Image Enhancement Algorithm
Bin Huang · Electronic Science and Technology · 2015
The characteristic and complexity of the underwater environment makes the underwater image poor in quality and low in contrast. An image enhancement algorithm based on spatial domain is put forward in this paper.This algorithm utilizes the average algorithm to estimate the background image first,then subtracts the background image,and finally sharpens the image which has had its background subtracted. An analysis of the simulation result demonstrates that the contrast of images processed meliorates distinctly and the edge of the target is much clearer.
