The autonomous obstacle detection and avoidance technology based on the lunar surface images is crucial for the lunar probe to achieve a safe landing on the moon surface. This article has discussed how to use the real-time data of the lunar surface images to judge whether it is safe or not to land on the scheduled landing site, and proposed an effective method for obstacle detecting and identifying:...
With investigation into the style of watercolor, a method is proposed to express the style of watercolor as particular regions and to adjust the style based on the regions. First, the image is segmented into several planar regions. Based on the attributes of these regions, the shapes can be adjusted and the color can be diffused and transferred in different ways to easily get various styles of watercolor...
This paper presents a new method to translate style of line drawings. Based on the theory of shape evolution, we translated the style of line drawings by transforming the control points of each stroke and deforming the mesh of the position-feature points of all strokes in a drawing. In this way, we adjusted the appearance and arrangement of strokes and obtained different styles of the drawing. Compared...
This paper presents a method to transform style for line drawings based on their mesh presentation. We first obtain the control points and position-feature points of strokes in a line drawing, then make a mesh for these special points of the strokes, and deform the polygons in mesh using theory of shape evolution. Finally, the arrangement of strokes is changed and the line drawing gets a different...
