Landscape Specification Resizing

Abstract : In this work, we introduce a method for resizing a landscape specification, i.e., a vector model containing a set of objects present in a virtual environment. Our goal is to change the landscape dimensions while keeping its overall appearance. Our method is based on the insertion and removal of objects in the specification, followed by some adjustments of the scene adapting the initial model to these changes. Besides the proposed approach for the positioning the objects, this method can be easily extended to use techniques of the state of the art for spreading objects in the landscape. The adjustment of the scene components consists in performing vertical or horizontal translations onto the position of the objects. It is based on a removal or insertion of paths in the grid created over the scene space using dynamic programming. In spite of dealing with a vector model, all proposed operations are performed in the pixel space. This technique is an adaptation of the Seam Carving for the context of vector landscapes specification. This model is simpler than common images, and thus, we can achieve results as good as those obtained in the image context, using simpler metrics.
