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 torepresentations of individual object parts linked by structuralinformation. Along this line of research, this talk will present a novelpart-based approach for automatic object detection using 2D images. Theapproach encodes the visual structures of the object to be detected andthe image by a 2D combinatorial map and a combinatorial pyramid,respectively. Within this framework, we propose to perform the searchingof the object as an error-tolerant submap isomorphism that will beconducted at the different layers of the pyramid. The approach has beenapplied to the detection of visual landmarks for mobile roboticsself-localization. Experimental results show the good performance androbustness of the approach in the presence of partial occlusions, unevenillumination and 3-dimensional rotations.
