The percentage of the area of the regions in relation to the area of all frames in the respective scene. This also includes image areas without pixel values. If you have defined no frame, this feature returns the percentage in relation to the whole image, i.e. the same value as Image Plane Area Percentage. In case of images with multiple scenes, the features is always calculated based on the area of a single scene.

Note that if your image does not contain areas without pixel values and you have not drawn a frame into the image, the following features all have the same result: Frame Area Percentage, Frame Data Area Percentage, Image Plane Area Percentage, and Image Plane Data Area Percentage.
