Abstract :
A grain boundary detection method based on partial differential equation(PDE) is proposed. The whole scheme is improved by introducing two PDE image processing techniques: PDE-based image filtering and segmentation. The noise in microscope image is suppressed with a edge-preserving filter: total variation flow. The second contribution is an extension of level set to segment color microphotograph, where multichannel information is used to identify grains. Experimental results on real thin section image of andalusite demonstrate the performance of the proposed method.
