摘要

An important problem in image labeling concerns learning with images labeled at varying levels of specificity. We propose an approach that can incorporate images with labels drawn from a semantic hierarchy, and can also readily cope with missing labels, and roughly-specified object boundaries. We introduce a new form of latent topic model, learning a novel context representation in the joint label-and-image space by capturing co-occurring patterns within and between image features and object labels. Given a topic, the model generates the input data, as well as a topic-dependent probabilistic classifier to predict labels for image regions. We present results on two real-world datasets, demonstrating significant improvements gained by including the coarsely labeled images.
