An Image Registration Algorithm Based on RANSAC and Mutual Information and Its Hardware Implementation
In the process of image fusiontwo different-source video inputs often cause parallax between the two images due to the difference in optical system and spatial positionwhich in turn causes the problem of blurred edges and artifacts during image fusion.Thereforeimage registration is required before image fusion.Regarding the problem that the current heterogeneous image registration has poor real-time performance which makes it impossible to be applied in practical engineeringan image registration algorithm based on RANSAC and mutual information is proposedwhich divides the registration operations of different dimensions into the initial registration and real-time registrationin the meantime the POWELL optimization algorithm is introduced to speed up the searchwhich maintains a high real-time performance without reducing the registration accuracy.Finallythe proposed algorithm is transplanted to embedded hardware and accelerated based on Zynqand an embedded image registration system with high accuracy and real-time performance is realized.
