Here, we propose its use for an augmented reality visualization. Introducing a double mirror system [11] the optical axes of both imaging systems (X-ray and optical) can be aligned. With this property both images can be merged or co-registered by only a planar transformation.

Surfimage uses the query-by-example approach for retrieving images and integrates advanced features such as image signature combination, multiple queries, query refinement, and partial queries. The classic and advanced features of Surfimage are detailed hereafter. Surfimage has been extensively tested on dozens of databases, demonstrating performance and robustness. Several experimental results are presented in the paper.
