Offered research work suggested a scheme to exclude the noise from ultrasound medical image. Such sorts of
pictures are tremendously affected by noise from various sorts of medicinal equipment like CT scan, MRI or ultrasound
systems. Some techniques of Denoising like mean, median, and spatial mask filtrating are frequently used procedures to
abolish the noise. Here hybrid median filter is introduced to eliminate high density impulse noise. Hybrid median filter is
a mixture of two filters. Suggested research work likewise gives the comparison outcomes of some formerly adapted
filtration techniques for denoising of impulsive noise in medical images. With enhancement in PSNR and lesser MSE
value to significant level also suggested work offers a unique scheme in hybrid median filtration. For better preserving
the edge and texture areas, an improved median filtering scheme has been advised in this work. The proposed filter is
effective in removing noises.
