  -This paper presents a semi automatic method used to segment color documents
into different uniform color plans. The practical application is dedicated to
administrative documents segmentation. In these documents, like in many other
cases, color has a semantic meaning: it is then possible to identify some
specific regions like manual annotations, rubber stamps or colored
highlighting. A first step of user-controlled learning of the desired color
plans is made on few sample documents. An automatic process can then be
performed on the much bigger set as a batch. Our experiments show very
interesting results in with a very competitive processing time.
