The theory of hierarchical image representations has been well-established in Mathematical
Morphology, and provides a suitable framework to handle images through objects or regions …

With the continuous growth of sensor performances, image analysis and processing
algorithms have to cope with larger and larger data volumes. Besides, the informative …

This paper introduces Pandora, a parallel algorithm for computing dendrograms, the
hierarchical cluster trees for single linkage clustering (SLC). Current parallel approaches …

Building detection is a challenging issue that requires efficient solutions in many operational
contexts. Hierarchical image representation through tree structures is known for its …

A new algorithm for computing the α α-tree hierarchical representation of a grey-scale digital
image is presented here. The technique is based on an efficient simplified version of the …

Image processing libraries play an important role in the researcher toolset and should
respect three criteria: genericity, performance, and interactivity. In short, genericity boosts …

Interactive video editing and analysis has a broad impact but it is still a very challenging
task. Real-time video segmentation requires carefully defining how to represent the image …

α-trees provide a hierarchical representation of an image into partitions of regions with
increasing heterogeneity. This model, inspired from the single-linkage paradigm, has …

Component trees can help filter images as they are easier to traverse than an image. The
most useful tree is the tree of shapes since it works with self-dual filters. However, creating …
