Find best camera settings

As reflections are one of our major problems when taking images from the drone, its important to conduct some tests to find the best camera setting to reduce the reflections to a minimum. One major problem which bring reflections into the detection algorithms and human vision is that there is no contrast at these areas anymore. Its like a nonlinearity which limits the information around these areas.

Even if the image is darker afterwards, we can increase the brightness / black white adjust the image afterwards. The decrease in the colordynamics range is not so important for us as nonlinearitys.

The informationdensity can be interpreted as entropy of a image. The higher the entropy of a image, the more information is in the image. As we are also interested in the informationdensity in the area of reflections or bright spots, we should also have a look at the entropy per area.

Tests including polarizationfilters will also be analyzed here.
