Abstract

In this paper, the spatial property of the magneto-static field generated by the stable current is discussed and exploited in image analysis. The region-division feature of the magnetic field generated by a current element on 2D plane is investigated experimentally for some simple test images. The virtual edge current in gray-scale images is presented by a magneto-static analogy, which is composed of the tangent edge vectors as a discrete form of the physical current element. The virtual magnetic field generated by the edge current in digital images is investigated experimentally, which is applied in region border detection and region division. A novel image segmentation method is proposed based on the virtual magnetic field generated by the edge current. The experimental results prove the effectiveness of the proposed method, and also indicate the promising application of the physics-inspired methods in image processing tasks.
