A Neighborhood Wavelet Coefficient Image Denoising with Improved Threshold

  title={A Neighborhood Wavelet Coefficient Image Denoising with Improved Threshold},
  author={Bo Wang and Lian Huang and Lei Liu},
Selection of threshold and threshold function is the key of wavelet-denoising. After wavelet decomposition and conversion, the low frequency part contains plenty of useful signals, while the high frequency part with noise distributed in the whole wavelet domain contains details of a few useful signals. Processing with fixed threshold and threshold function may cause loss of details of the useful signals of high frequency part. In this article, decomposition scale is introduced for threshold and…

Image Denoising Based on Wavelet Modulus Maxima and Neyman-Pearson Principle Threshold
Simulation results show the proposed method can efficiently denoise, such as increasing Signal-to-Noise Ratio (SNR), slowing Mean Square Error (MSE) and Relative Entropy (RE), while preserving the details of the original image.
An improved wavelet algorithm of image denoising
Experimental results show that this algorithm inherits the advantage of the hard and soft thresholding function and overcomes their weakness; more over, it can well reserve the detail of the image.
Image denoising using neighbouring wavelet coefficients
This paper proposes one wavelet image thresholding scheme by incorporating neighbouring coefficients for both translation-invariant (TI) and non-TI cases, and investigates different neighbourhood sizes to find that a size of 3 × 3 or 5 × 5 is the best among all window sizes.
A generalized image denoising method using neighbouring wavelet coefficients
This paper extends the idea of Cai and Silverman for developing a new image denoising method and determine the coefficients of neighboring window for every subband and shows that in most of the cases, the proposed method performs better than the NeighRink, ModiNeighShrink, and IIDMWT in terms of peak signal- to-noise ratio and structural similarity index measure.

The theoretical analyses and experimental results presented show that this method can keep an image's edges from damage and can increase the PSNR up to 1~2 dB, and the conclusion is drawn that edge detection and denoising are two important branches of image processing.
An Improved Image Denoising Method Based on Wavelet Thresholding
An improved method is proposed, that determines a threshold as well as neighbouring window size for every subband using its lengths, that is better than the existing methods in terms of peak signal-to-noise ratio (PSNR) i.e. visual quality of the image.
An improved compromise for soft/hard thresholds in wavelet denoising
The characteristics of two traditional wavelet compromise methods,referred to as the soft-thresholding method and the hard-thresholding method,were analyzed in the wavelet domain.A new compromise
Incorporating Information on Neighboring Coefficients Into Wavelet Estimation
In standard wavelet methods, the empirical wavelet coe cients are thresholded term by term, on the basis of their individual magnitudes. Information on other coe cients has no in uence on the
