Abstract  

Segmenting the plant leaf by a fixed model is problematic due to different imaging conditions, such as backgrounds, shadows and reflections. In this paper,interactive plant leaf segmentation method based on robust random walk is proposed. The interactive strategy is employed to propagate prior information of user-specified pixel, and robust random walk algorithm is used to realize plant leaf segmentation. The relationship of pairwise pixels is considered based on random walk and a super-pixel-consistent constraint is added to make the edges of segmentation smooth. Since the random walk algorithm only considers pairwise pixel relations, it is sensitive to the specified and connected pixels. The prior information of specified pixel is obtained through human-machine interaction. On the basis of random walk model, a log-likelihood ratio is used to predict the probability of a pixel belonging to the background and guide the label propagation. Experiments on plant leaf images in loose controlled and uncontrolled environments show that the proposed method obtains smoother and more robust plant leaf segmentation images than other methods.
