Holography is the optimal and the final choice among several techniques for imaging and displaying the three-dimensional (3D) objects. In this paper, we propose a new denoising algorithm for digital hologram using Fresnel transform (FT). The proposed algorithm initially transforms a digital hologram into frequency-domain data through a FT, and separates the object from the background in the transformed image. Experimental results show that the technique to reduce noise in a natural 2D image such as a smoothing filter can reduce the noise to improve the image quality for a digital hologram. We expect that the conclusions of this paper will be a very useful technique for further work in the area of signal processing scheme for electronic holographic video service.
