# Normalize hist with Norm_L1 doens't work ?

I am using the normalize function with this params:

```
normalize(hist, hist, 255, NORM_L1);
```

This should mean that the sum of every values inside the mat should equal to `= 255`

But later if i sum all values i get another value

```
sum(hist) != 255
```

To fix this error I need to call the normalize function like this:

```
normalize(hist, hist, 255, 0, NORM_L1);
```

Now I get:

```
sum(hist) == 255
```

Is this an intended behavior ?
