(Perceptually-relevant Retrieval Of Figurative Images)

In this Project we aim to invent and develop new techniques for the retrieval of figurative images from large databases. Our techniques will be based on the extraction and matching of perceptually relevant shape features, thereby overcoming many of the limitations of existing methods. This project will develop and evaluate algorithms for:

• Percetual segmentation of raw images, and grouping of shape elements.
• Matching of geometrical patterns representing shape features.
• Partial matching: fitting part of one shape with part of another.
• Indexing shape features in huge database of figurative images.
• Indexing the relative spatial layout of shape features within these images.

The developed algorithms will be experimentally verified in a prototype system, and subjected to rigorous evaluation on databases with independently-validated ground truth.
