2. DarkenScene: Operation to darken an image or specific annotation classes in that image. Requires a darkness parameter [0, 1] in config.

3. BrightenScene: Operation to brighten an image or specific annotation classes in that image. Requires a brightness parameter [0, 1] in config.

4. RandomBrightness: Operation to randomly brighten an image or specific annotation classes in that image based on a random distribution. Requires a distribution parameter (normal or uniform) in config.
