Add a user defined level of white noise to the input image.
function call:
[out_img1]=vsg('AdditiveNoise',in_img1,num1);
Arguments:
in_img1
input image, 3 channel
num1
– an integer which specifies the range of the additive noise.
Description:
out_img1
– An image which has dimensions the same as the input image. This is the
input image with noise added. Max noise level =num1/2, min noise level
=(-num1)/2.
Example:
img = openimage('lake.jpg');
[out_img1]=vsg('AdditiveNoise',img,50);
Notes:
1. For DICOM images,
the function operates on all slices separately.
2. For
