The filtered image is obtained by placing the median of the values in the input window, at the location of the center of that window, at the output image. The median is the maximum likelihood estimator of location in the case of Laplacian noise distribution. For relatively uniform areas, ...
The original 256 x 256 pixel image corrupted by additive Gauss noise and the alpha-trimmed mean filtered image using a 5 x 5 pixel square mask and P = 3.ParametersHDIB hDIB Handle of the DIB to filter. int N This parameter specifies the size of the square mask. N cannot be less ...
The WFM-filtered output signal is the mean value of the corrupted signals in a sample matrix, and these signals are weighted by a membership grade of an associated fuzzy set stored in a knowledge base. The knowledge base contains a number of fuzzy sets decided by experts or derived from ...

The raw image is first filtered by max-mean/max-median filter. Then the filtered output is subtracted from the original image to enhance the potential targets. A thresholding step is incorporated in order to limit the number of potential target pixels. The threshold is obtained by using the ...
A image of the North-East coast of Spain is used for analyzing the influence of the parameters of the ldquoMean Shiftrdquo method. The quality of the filtered images is evaluated by inspection and using other objective parameters. The results are compared to those obtained using the Lee filter...

image with a Gaussian or bilateral filter and then, examines the difference between the noisy and filtered images. To suppress the noise and retain the image details, the wavelet decomposition and thresholding were performed. The final restoration is achieved by using wavelet reconstruction, which ...
Each of such binary images (0, tissue absent; 1, tissue present) is then filtered (or smoothed) to generate “density” images; the image of white-matter density shown here indicates, at each voxel, local concentration of WM on a continuous scale from 0 to 1 (the hotter the color, ...
That is all — now alpha-trimmed mean calculated and signal, 1D in our case, filtered by alpha-trimmed mean filter! Let us make resume and write down step-by-step instructions for processing by alpha-trimmed mean filter.Alpha-trimmed mean filter algorithm:...
