description: The subject of the graduate qualification work is âImproving the quality of ultrasound images by filtering noiseâ. The given work is devoted to the development of a method for filtering speckle noise on ultrasound images using a neural network. To achieve this goal, the type of noise in ultrasound images was evaluated, training images with superimposed noise were synthesized, a neural network for filtering speckle noise was implemented and the size of its optimal parameter was determined by the chosen metric. As a result of the work, a method for filtering speckle noise on ultrasound images was developed. The neural network approach was compared with classical methods of local filtering on a set of test images. The neural network approach makes it possible to remove speckle noise more efficiently in comparison with standard methods. The developed speckle noise filtering method can be applied in the future for ultrasound image processing, which will allow for more accurate diagnostics, detection of objects and segmentation of areas. Open educational resources and information search and analysis programs were used. MATLAB automated development tools were used. MATLAB software is used.
