Benjamin_Loison 674f87d480 Remove unnecessary iterativeMean parentheses and rename addElement to add 2024-04-26 14:22:59 +02:00
Benjamin_Loison 7af96d6bf6 Add iterativeMean to utils 
Verified with:

```py
myIterativeMean = iterativeMean()
print(myIterativeMean.mean)
myIterativeMean.addElement(2)
print(myIterativeMean.mean)
myIterativeMean.addElement(3)
print(myIterativeMean.mean)
```

Note that cannot simplify as follows in the general case of using images as
`element`s for instance:

```diff
diff --git a/datasets/raise/utils.py b/datasets/raise/utils.py
index fba5523..a116edb 100644

Benjamin_Loison f88b6ec1a9 Save mean of each color channel to merge them into a single image being 
the mean of images

Otherwise for each color channel could use:

```py
plt.imsave(f'{fileName}.png', colorMean)
```

Benjamin_Loison 65708e4977 Correctly implement mean denoiser 
Used to have:

```py
imageDenoisedNpArray = imageNpArray - means[color]
imageNoiseNpArray = imageNpArray - imageDenoisedNpArray
```

so:

```py
imageNoiseNpArray = means[color]
```

then we mean the mean...

While should have:

```py
imageDenoisedNpArray = means[color]
```
