Abstract :

Now a day in regular emerging field of technology use of digital imaging grows. Digital image processing refers to processing of digital images by the digital computer to improve the quality of image and enhancing the image and their edges. DIP is vast area of work. This digital image processing is used in many fields like in photography, high security number plate recognition system and in medical field also. This paper mainly focuses on pre- processing step of digital imaging, noise present in digital image and how filtering technique improves the quality of image and reduces the noise in synthesis medical images. In this paper we take ultrasound medical images for pre-processing on digital image processing. So the input is ultrasound image for pre-processing.
