How can we divide a BGR image into three channels?

To create a BGR image from three separate channels, we simply need to call the merge function, passing as input a tuple with the channels. So, to create the BGR image from the Blue channel, the first element of the tuple should be the Blue channel and the remaining ones should be the “empty channel”.
