Morphological object picking based on the color tree of shapes

Abstract: The Tree of Shapes is a self-dual and contrast invariant morphological tree that provides a high-level hierarchical representation of images, suitable for many image processing tasks. Despite its powerfulness and its simplicity, it is still under-exploited in pattern recognition and computer vision. In this paper, we show that both interactive and automatic image segmentation can be achieved with some simple tree processings.To that aim, we rely on the "Color Tree of Shapes", recently defined. We propose a met… Show more

“…In addition to the references given throughout the paper, related either to the context of our work or to its theoretical background, several other works shall be mentioned. Actually the notion of path on tree nodes also appear in [7] to assign to each node a label and then perform some scribble-based segmentation, in [8] to count level lines and build a multi-variate tree of shapes, and in [12] to compute some curvilinear variation and separate an object from its background. The notion of barrier used on the tree of shapes is also close to the one of shape saliency used in [24].…”

“…The multi-class classification problem is addressed with an extension of the interactive segmentation algorithm proposed in [14]. In this phase of preliminary experiments, the classification of the nodes is performed on the ToS (i.e., channel-wise) instead of using the Multivariate Tree of Shapes [15].…”

“…Thus, performing the classification directly on the ToS (i.e., classification of the nodes) should provide comparable results of the SDAPs since they carry information which is present in the ToS. The adopted scheme is the interactive segmentation algorithm proposed in [14] for the Multivariate Tree of Shapes [15,16]. The algorithm is extended to a multi-class classification problem, with multispectral data sets acquired by QuickBird and IKONOS sensors over urban areas.…”

“…This issue has been addressed in the framework of the Image Foresting Transform (IFT) [11] with the Differential Image Foresting Transform (DIFT) [10] a WS-based and fuzzy-connected segmentation method, whose response time for interactive segmentation is proportional to size of the modified regions of the scene. Interactivity has also been addressed in the context of object segmentation with hierarchical representations, especially for trees based on threshold decomposition i.e., component trees [20] or tree of shapes [5,19].…”
