from PIL import Image
# Loads the image from the specified file
image = Image.open("image.png")
# Get the number of rows and columns in the image
rows, cols = image.size
# Creates values using a normal distribution with a mean of 0 and standard deviation of 15, the values are converted to unit8 which means the values are between 0 and 255
noise = np.random.normal(0,15,(rows,cols,3)).astype(np.uint8)
# Add the noise to the image
image = np.array(image)
noisy_image = image[:,:,:3] + noise
# Creates a PIL Image from an array
noisy_image = Image.fromarray(noisy_image)
