Generating good-looking computer-generated images requires that the light in the scene is balanced. If you have too much light, then parts will be burned out and with too little light then the result will be too dark. This is usually done manually when generating one image at a time. But when the process is automated, and several thousand images are produced every day from rooms with different size, windows, lights, glossy and/or matt materials, and other prerequisites then this needs to be done automatically.
Beside changing the amount of light in the room (by reducing the amount of light from the windows for example), this could also be achieved by a combination of light in the room and exposure of the camera.
The master thesis consists of two parts. First to identify what parts that can be configured in a modern render pipeline with respect to lights. The second part is to implement an algorithm that automatically configures the render pipeline so that it produces images that are not too bright and not too dark.
