Image retrieving in underwater optical imaging systems based on Fourier-wavelet deconvolution
Ali asghar Askari * 1, Lale Rahimi
Abstract:   (2049 Views)
Absorption and scattering of water and in-water particles are two main factors that limit the performance of underwater optical imaging systems. Captured images of underwater imaging systems are blurred and noisy due to these effects. Fourier deconvolution was used to retrieve the original images. Deconvolution is a noise sensitive process. To suppress noise amplification during deconvolution, Tikhonov-wavelet filter has been used to deconvolve and denoise the captured image, simultaneously. Simulations show that this method is an efficient technique to extend the dynamic range of underwater optical imaging systems.
