Medical Image Enhancement to Remove Speckle Noise with Various Filters

Project Description

Speckle is signal correlated noise. In ultrasound imagery also other sources of noise are presente depending on the specific application. At least one has to consider the thermal and electronic noise added at the receiver. This section offers some idea about various noise reduction techniques. Unfortunately, the presence of speckle noise in these images affects edges and fine details which limit the contrast resolution and make diagnostic more difficult. Ultrasound imaging system is widely used diagnostic tool for modern medicine. It is used to do the visualization of muscles, internal organs of the human body, size and structure and injuries. Proposed filtering is a techniques for the removal of speckle noise from the digital images. Quantitative measures are done by using signal to noise ration and noise level is measured by the standard deviation
