| Abstract: | This paper proves the existence of rotationally symmetric solutions to a curvature flow in image processing. The flow includes the level sets flow and the mean curvature flow projected onto the normal. Sharp estimates are obtained for these solutions.. |
| Keywords: | level sets flow mean curvature flow singular ordinary differential equation priori estimate rotationally symmetry |
