Digital Image Noise Processing Based on MATLAB Software

On the basis of the analysis of digital image
effect improvement basic theory research, a clearer
processing algorithm of university image effect is
proposed to make the image more distinct and more
quickly presented.By MATLAB software to write
relevant simulation code, respectively using the mean
filtering method and median filtering method to denoise
the image, so as to improve the image clarity, brightness,
finally the two methods are compared, in order to better
understand the theoretical knowledge. The software
running results show that this method can achieve image
denoising succinctly and accurately, and has high
learning and practical value.
