@misc { , title = {A general framework for partial to full image registration.}, abstract = {Image registration is a research field in which images must be compared and aligned independently of the point of view or camera characteristics. In some applications (such as forensic biometrics, satellite photography or outdoor scene identification) classical image registration systems fail due to one of the images compared represents a tiny piece of the other image. For instance, in forensics palmprint recognition, it is usual to find only a small piece of the palmprint, but in the database, the whole palmprint has been enrolled. The main reason for the poor behaviour of classical image registration methods is the gap between the amounts of salient points of both images, which is related to the number of points to be considered as outliers. Usually, the difficulty of finding a good match increases when the image that represents the tiny part of the scene has been drastically rotated. Again, in the case of palmprint forensics, it is difficult to decide a priori the orientation of the found tiny palmprint image. We present a rotation invariant registration method that explicitly considers that the image to be matched is a small piece of a larger image. We have experimentally validated our method in two different scenarios: palmprint identification and outdoor image registration.}, note = {INFO COMPLETE (added by contact 30.01.2023 GB) PERMISSION GRANTED (hosted on arXiv under CC BY 30.01.2023 GB) DOCUMENT READY (downloaded from arXiv 30.01.2023 GB) ADDITIONAL INFO: Carlos Moreno-Garcia}, publicationstatus = {Unpublished}, url = {https://rgu-repository.worktribe.com/output/1713031}, keyword = {Image Registration, Candidate Voting, Generalised Hough Transform, Hungarian method, Iterative Closest Point, Bipartite Graph Matching}, author = {Moreno-GarcĂ­a, Carlos Francisco and Serratosa, Francesc} }
