【摘要】：在數(shù)字全息再現(xiàn)像過程中,受到噪聲干擾,再現(xiàn)像質(zhì)量差,對比度低。為了解決當(dāng)前數(shù)字全息再現(xiàn)像方法的缺陷,獲得更優(yōu)的數(shù)字全息再現(xiàn)像質(zhì)量,提出基于輪廓波變換的數(shù)字全息再現(xiàn)像質(zhì)量改善方法。首先采用小波變換去除數(shù)字全息再現(xiàn)像噪聲,然后采用輪廓波變換方法對數(shù)字全息再現(xiàn)像再次去噪,最后采用數(shù)字全息再現(xiàn)像實驗進(jìn)行可行性分析。結(jié)果表明,本文方法有效去除數(shù)字全息再現(xiàn)像的噪聲,獲得了理想的數(shù)字全息再現(xiàn)像,有利于后續(xù)的數(shù)字全息再現(xiàn)像處理。
[Abstract]:In the process of digital holographic image reconstruction, the quality of the reconstructed image is poor and the contrast is low due to noise interference. In order to solve the defects of the current digital holographic reconstruction method and obtain better digital holographic reproduction image quality, a new method based on contour transform is proposed to improve the digital holographic reconstruction image quality. Firstly, wavelet transform is used to remove the noise of digital holographic reconstructed image, then the contour wave transform method is used to de-noise the digital holographic reconstructed image again. Finally, the feasibility analysis of digital holographic reconstruction image experiment is carried out. The results show that the proposed method can effectively remove the noise of the digital holographic reconstruction image and obtain the ideal digital holographic reconstruction image, which is beneficial to the subsequent digital holographic reconstruction image processing.
