In order to improve the image denoising ability, the wavelet transform (WT) and independent component analysis (ICA) are both introduced into image denoising in this paper.
Although these two algorithms have their own advantages in image denoising, they are unable to reduce noises completely, which makes it difficult to achieve ideal effect.
Therefore, a new image denoising method is proposed based on the combination of WT with ICA (WT-ICA).
For verifying the WT-ICA denoising method, we adopt four image denoising methods for comparison: median filtering (MF), wavelet soft thresholding (WST), ICA, and WT-ICA.
From the experimental results, it is shown that WT-ICA can significantly reduce noises and get lower-noise image.
Moreover, the average of WT-ICA denoising image’s peak signal to noise ratio (PSNR) is improved by 20.54% compared with noisy image and 11.68% compared with the classical WST denoising image, which demonstrates its advantage.
From the performance of texture and edge detection, denoising image by WT-ICA is closer to the original image.
Therefore, the new method has its unique advantage in image denoising, which lays a solid foundation for the realization of further image processing task.
