In experimental soil mechanics, it is important to study the motion of sand grains under high pressures. Before measuring the movement and deformation of a fraction of sand, we should detect it at first. But it is very difficult to distinguish sands automatically from each other in a dense grain image. In this paper, an approach of segmentation based on level set is proposed for dense sand grain images...
In experiments of soil mechanics, it is important to study the motion of sand grains at high pressures. Technologies of image segmentation and object tracking can help to resolve this problem. Aiming at the dense sand grains images, this paper proposes a method to track sand grains from image sequences. A novel approach of dense grain segmentation based on boundary exploration is proposed. Firstly,...
