Abstract : This final report describes our work on three topics. First is construction of 3-D models by use of smart 3-D pen which enables direct 3D input and manipulations. The other two efforts deal with the problem of aerial image analysis. First of these is about detecting changes in man made structures using a paradigm of comparing new images to 3-D models constructed from previous images rather than the previous images directly. The second is about detecting and describing building structures from multiple views using hierarchical grouping and matching techniques to overcome ambiguity problems.
