Title: Part-based Object Detection into a Hierarchy of Image
Segmentations Combining Color and Topology


Object detection is one of the key components in computer vision systems.
Current research on this topic has shifted from holistic approaches to
representations of individual object parts linked by structural
information. Along this line of research, this talk will present a novel
part-based approach for automatic object detection using 2D images. The
approach encodes the visual structures of the object to be detected and
the image by a 2D combinatorial map and a combinatorial pyramid,
respectively. Within this framework, we propose to perform the searching
of the object as an error-tolerant submap isomorphism that will be
conducted at the different layers of the pyramid. The approach has been
applied to the detection of visual landmarks for mobile robotics
self-localization. Experimental results show the good performance and
robustness of the approach in the presence of partial occlusions, uneven
illumination and 3-dimensional rotations.
