In this paper, we present an interactive algorithm for segmentation of color images. The user first draws some scribbles into regions that must be discriminated, and the segmentation is then automatically obtained. The segmentation is based on the computation of geodesic distances within color monogenic signal (CMS) fields. An important difference with state-of-the-art methods is that scribbles, which are often segments, are sample pixels picked up by the user. It results in a much more user-friendly segmentation process. Experimental results and comparisons with recent methods show the effectiveness of the approach.
