A switching scheme for median filtering which is suitable to be a prefilter before some subsequent processing e.g, edge detection or data compression is presented to remove impulse noises in digital images with small signal distortion. The switching procedure is based on the local measurements of ...
When employed for image processing, however, median filters still exhibit blurring for large window sizes, or insufficient noise suppression for small window sizes. In this dissertation we propose an adaptive window-size median filter algorithm which can achieve a high degree of impulse noise ...

The Median Filter block replaces the central value of an M-by-N neighborhood with its median value. If the neighborhood has a center element, the block places the median value there, as illustrated in the following figure. The block has a bias toward the upper-left corner when the neighbor...
The Median Filter block applies a median filter to each pixel of an input image. For each M-by-N neighborhood, the filter replaces the central value with the median value of the neighborhood. If the neighborhood has a center element, the block replaces the center pixel with the median val...
The median filter is one of the basic building blocks in many image processing situations. However, its use has long been hampered by its algorithmic complexity O(tau) of in the kernel radius. With the trend toward larger images and proportionally larger filter kernels, the need for a more ...
We propose a fast median filtering algorithm for signal smoothing in image processing. The median filter is the well-known method in image processing because it preserves edges effectively while reducing the impulsive noise. However, it has a problem that execution speed is slow because it uses a...
