Re: each_channel decorator

      OK, so it is basically just a decorator which calls color.rgb2gray and passes the converted image to the function?

Sorry, but I do not understand what this decorator does. Could you provide a short example?
@each_channel
def some_gray_level_filter():
  return gray_image
image = data.something()
gray_image = color.rgb2gray(image)
some_gray_level_filter(gray_image)
some_gray_level_filter(image) <-- this works too
