| Abstract: |
| In this paper, we investigate image denoising in signal processing. This paper presents a Canny operator edge detection by wavelet thresholding approache based on wavelet transforms. The experimental results show that this approache can keep image's edges from damaging. |
| Key words: image denoising wavelet transform Canny operator edge detection |
