We are pleased to announce that the following paper has been accepted in the 21st International Conference on Image Processing (ICIP'14). Tree of Shapes of Multivariate Images: Leads and Traps Edwin Carlinet¹² Thierry Géraud¹² ¹EPITA Research and ²Laboratoire d'Informatique Development Laboratory (LRDE) Gaspard-Monge (LIGM) edwin.carlinet(a)lrde.epita.fr The Tree of Shapes is a morphological tree that provides an high-level hierarchical representation of the image suitable for many image processing tasks. This structure has the desirable properties to be self-dual and contrast-invariant and describes the organization of the objects through level lines inclusion. Yet it is defined on gray-level while many images have multivariate data (color images, multispectral images...) where information are split across channels. In this paper, we propose some leads to extend the tree of shapes on colors with classical approaches based on total orders, more recent approaches based on graphs and also a new distance-based method. Eventually, we compare these approaches through denoising to highlight their strengths and weaknesses and show the strong potential of the new methods compared to classical ones. -- Edwin Carlinet Doctorant à l'Université Paris-Est / EPITA
