Floating object image treatment based on wavelet

The images, photographed through a submarine periscope, are ambiguous because of submarine periscope light path energy dissipation and bad conditions. The images can be processed by Fourier transform. But the processing effect is not good. In this paper, we process the images with wavelet. Our works include removing image noise, enhancing image edge, enlarging image and diminishing image. Experiment shows that the experiment results are better.
