Evaluation of visual balance for automated layout

Layout refers to the process of determining the size and position of the visual objects in an information presentation. We introduce the WeightMap, a bitmap representation of the visual weight of a presentation. In addition, we present algorithms that use WeightMaps to allow an automated layout system to evaluate the effectiveness of its layouts. Our approach is based on the concepts of visual weight and visual balance, which are fundamental to the visual arts. The objects in the layout are each assigned a visual weight, and a WeightMap is created that encodes the visual weight of the layout. Image-processing techniques, including pyramids and edge detection, are then used to efficiently analyze the WeightMap for balance. In addition, derivatives of the sums of the rows and columns are used to generate suggestions for how to improve the layout.
