An autocorrelation function-based method used for image denoising with
accuracy and efficiency
Abstract
Noise is always inevitably appeared in images, which directly affects
the performance of machine vision applications. Currently, the commonly
used denoising methods can be divided into three strategies: the
filtering-based, model-based, and deep learning-based methods. However,
they are always difficult to get the considerable accuracy and
efficiency simultaneously. In this study, a novel denoising method based
on autocorrelation function is investigated, which improve the image
quality by utilizing the independence of useful periodic information and
noise. Simulations and experiments compared with the current denoising
methods confirm that the investigated method has a good comprehensive
effect on noise reduction and efficiency improvement.
