The holographic camera system for research and analysis on marine microorganisms and particles has a wide application prospect. Because of the special imaging technique (the holographic imaging technology) and the special imaging environment (seabed), there are a variety of different oblique stripe noises in the holograms. The existence of oblique stripe noises seriously affect quality of reconstructed image of the marine biological hologram and further processing, and the present methods for common stripe noise are no longer suitable. An effective method is proposed to deal with the oblique stripe noises. For the periodic oblique stripe noise, the local threshold method is adopted to find out the frequency center of the noise, and the Gaussian notch filter is utilized to eliminate the noise. For the aperiodic oblique stripe noise, the linear equation is used to simulate the bright line of the noise in the frequency domain, and the partial notch filter is exploited to depress the noise. Simulation results illustrate that the proposed method can filter out the periodic oblique stripe noise completely as well as the aperiodic oblique stripe noise mostly, and the useful information of the holograms can be kept.
