2022-02-03 01:41:31 CSDN Q & A

The phenomenon and background of the problem

I found that other people's papers are given by Gaussian noise sigma Choice is 15 20 50 and skiamge In Chinese var Only 0.0 A few I want to ask what is the relationship between these two parameters How to convert

for image_name in image_names:
if os.path.isfile(path + image_name):
img=Image.open(os.path.join(path,image_name))
img=np.array(img)
noise_gs_img=util.random_noise(img,mode='gaussian',mean=0,var=0.02)# gaussian

Operation results and error reporting contents
My solution ideas and tried methods
What I want to achieve
