Semantic Region Labeling
People: Jason Corso, Albert Chen
Past Collaborators: Zhuowen Tu (UCLA), Alan Yuille (UCLA) Natural scene understanding, segmenting and labeling image regions with semantically meaningful labels (e.g., trees, cars, etc.), has increasingly attracted attention since it is a key aspect in image understanding and image search. In general, region labeling is a very hard problem due to the large variation of natural images ranging from indoor to outdoor, small to large scale, and rural to city scenes. Moreover, some type of objects, e.g. buildings, may have very different designs and appear very differently under different viewing directions and scales. We have proposed a supervised approach for combined image segmentation and region labeling. We use a hybrid discriminative-generative modeling scheme. The discriminative term is modeled by an extension of the probabilistic boosting tree algorithm that does multi-class representation in a tree structure. It can better handle the variability in natural image patches. The generative terms captures the local context of the image regions. The method has been applied to medical images (see the brain tumor page for examples). It has been applied to natural photos. Here is a montage on the MSRC v2 dataset. We've also worked with fused overhead imagery and LIDAR data for detecting buildings. We're currently working on extensions of our methods to video.
