The various image denoising techniques that are proposed from time to time are offering denoising techniques preserving the original image features. The denoising is so important because ultrasound imaging today has gained wide acceptance due to its safety, easy imaging procedure, low cost and adaptability. However the main shortcomings of this process is poor quality of images which is further degraded due to the presence of speckle noise and other types of noise. Hence it has become vital to remove noise while preserving important datails and features of the image. This paper will introduce a unique method to speckle noise filtering using median filters, wavelet and SRAD filters.

INTRODUCTION Compared to other medical imaging techniques ultrasound images suffers from lower image contrast, low Signal to noise ratio, signal dropouts, shadowing of structures, variable intensity problem etc. Moreover very often they contain high noise contents against poor contrast. This ultimately results in blurred image, missing edge points, fake edge points etc. Hence due to complex and changing shapes it becomes difficult to obtain a correct edge map which is vital for diagnosis purpose. Speckle noise comes up as a result of interference between multiple scattering beams and main reflected signal. Speckle noise is a granular noise that inherently exists in and degrades the quality of the images. Generally it is found in ultrasound image and radar image.

The corrupted pixels are either set to the maximum value, which is something like a snow in image or have single bits flipped over. This kind of noise affects the ultrasound images. Speckle noise has the characteristic of multiplicative noise. Speckle noise follows a gamma distribution and is given as Where, α is variance and g is the gray level. 2. NECESSITY TO REMOVE SPECKLE NOISE As most prevalent artifact in ultrasound image which makes object detection and recognition more difficult, reduction of speckle directly improves the value of the sonogram. Because Ultrasound Images have very little contrast, edge detection is essential to object detection. Ultrasounds depend more heavily on edge detection than other medical imaging modalities. Speckle noise can distort or hide edges making object detection less reliable. Objects such as tumors or birth defects can go undetected and thus untreated 3. SPECKLE NOISE STATISTICS The Rayleigh density function, and its extension, the Rice density function, provide a good starting point for the model for the statistics of the envelope signal. The Rayleigh density function provides a good model for the backscattered echo signals when the scatterer density is very large (>10 scatterers per resolution cell). This model has been used extensively for such fully formed speckle situation. Similarly, the Rice model provides a good model for the presence of coherent backscatter. 4. REMOVING SPECKLE NOISE To develop a despeckling algorithm to filter out speckle noise we have know the mathematical model of the speckle noise .The simplified model can be described as follows: As we know speckle noise is a multiplicative noise, the logarithm of the noisy image is taken to convert the noise function to an additive one .Hence for a possible imaging let F1(m,n)=F2(m,n)*N(m,n) --------------------------(1) where F1,F2 and N are the noisy image , original image without noise and noise function respectively.By taking log on both sides eqn (1) becomes Log{F1(m,n)}=Log{F2(m,n)}+Log{N(m,n)}---(2) In eqn (2) as we observe the noise becomes an additive noise which is processed by various noise removing filters. Denoised Image is obtained by taking the exponential of the image matrix. 5. MEDIAN FILTER Median filter is a nonlinear spatial filter which is good at removing pulse and spike noise. The filtering process is described here-

For c(x), they have two coefficients options: Where k is the edge magnitude parameter. c(x) is the conduct coefficient along four directions. In practical design, the diffusion coefficient c(âI ) is anisotropic, and thus itâs called anisotropic diffusion. The option 1 of the diffusion coefficient favors high contrast edges over low contrast ones. The option 2 of the diffusion coefficient favors wide regions over smaller ones. The edge magnitude parameter k controls conduction as a function of gradient. If k is low, then small intensity gradients are able to block conduction and hence diffusion across step edges. A large value of k can overcome the small intensity gradient barrels and reduces the influence of intensity gradients on conduction. Usually k ~ [20,100]. This method can be iteratively applied to the output image, and the iteration equation is: where I (n) is the output image after n iterations. λ is the diffusion conducting speed, usually we set λ<=0.25. 7. WAVELET BASED DENOISING Wavelet transform(WT) is another transformation method like Fourier transform(FT) except that time and frequency information is obtained simultaneously in the later. FT has the drawback that it cannot provide time information of the frequency bands which is specially important in case of non stationary signals. Though STFT although provides time frequency information of the signal ,it suffers from resolution problem. WT removes this resolution problem also. As most of the practical signals are non stationary type , it is crystal clear that WT has higher preference in signal analysis. The continuous wavelet transform is given by Xw(a,b)=(1/âa)â«[h*{(t-b)/a}x(t)] Where h(t) is the wavelet basis function and x(t) is the original signal. Wavelet techniques are widely used for image denoising and image compression. The wavelet denoising method decomposes the signal image into wavelet basis and shrink the wavelet coefficients to remove speckle. At every level the coefficients are run through soft thresholding process. After thresholding inverse wavelet transform is performed to reconstruct the image. In short, âą Decomposition: A wavelet chosen with level N. The wavelet decomposition of the signal is computed at level N. âą Threshold detail coefficients: For each level from 1 to N, a threshold selected and soft thresholding applied to the detail coefficients. âą Reconstruction: Wavelet reconstruction using the original approximation coefficients of level N and the modified detail coefficients of levels from 1 to N is performed.

PROPOSED METHOD In our method we first produce artificial speckle noise which is then combined with synthetic ultrasound image to produce noisy test image. At first, denoising is performed using median filter to move long tailed noise such as negative exponential , salt and pepper noise ,spike or pulse noises etc. This of course causes minimum blurring to the image. The process is specially useful if the image contains strong unusual spikes. Secondly, the noisy image is then processed by Wavelet denoising by passing the noisy signal through a wavelet filter and soft thresholding the detail coefficients for speckle removal. At the third step ,SRAD2 filter is used to enhance the contrast of the image, smoothing homogeneous regions and to retain image edges. The whole process can be shown using block diagram as follows: Figure 1: Block Diagram Finally MSE, RMSE, SNR, PSNR are calculated the proposed method and compared with other types of filters. The process is done for three test images. Window size remains fixed 3Ă3. 9. SIMULATION Here we have used MATLAB as a simulation software .The filters codes are written and image processing toolbox is also used to enhance the simulation. 10. COMPARISON PARAMETERS To determine the image enhancement we have measured The Root Mean Square Error (RMSE), signal-to-Noise Ratio (SNR), and Peak Signal to Noise Ratio (PSNR) of the noisy image The RMSE, SNR, and PSNR are provided below.
