Due to limited computational resource, image matching on mobile phone places great demand on efficiency and scale invariant. Though spectral matching (SM) with pairwisely geometric constraints is widely used in matching, it is not efficient and scale invariant for applications in mobile phones. The main factor that limits its efficiency is that it requires to eign-decomposition of a large affinity...
Spectral decomposition subject to pairwise geometric constraints is one of the most successful image matching (correspondence establishment) methods which is widely used in image retrieval, recognition, registration, and stitching. When the number of candidate correspondences is large, the eigen-decomposition of the affinity matrix is time consuming and therefore is not suitable for real-time computer...
