Abstract:
This paper proposes a novel image denoising method through the self-organizing feature map (SOFM) which exploits spatial local correlation among image neighbouring wavelet coefficients. It is well known that wavelet coefficients are both intrascale and interscale statistical dependencies. SOFM algorithm is popular for unsupervised learning and data clustering and can capture persistence properties of wavelet coefficients. Experimental results show that the performance of the proposed method is practicable and effective for image denoising. |
| Keywords and phrases: self-organizing feature maps, image denoising, neighbouring wavelet coefficients. |
