Abstract: Digital mage registration represents a problem of great importance in various field such as medicine, security, astronomy, etc. It refers to the problem of matching two or more pictures of the same scene taken at different times, by different sensors, different viewpoints. It is necessary to find a spatial relationship between these images, usually called reference image and floating images. This relationship can be a linear transformation, also known as rigid transformation, or non-linear (nonrigid, elastic) transformation. Image registration techniques can be feature based or area based. Feature based techniques provide transformation which maps floating images to the reference image based on some common features between them. These techniques are limited due the need to find the reliable feature correspondence between images. Area based techniques work with pixel values and search for the optimal parameters for transformation that aligns floating images to the reference image. In order to determine registration quality, some similarity measurement should be defined. Some of the most common similarity measurements are squared intensity differences, cross correlation, mutual information, etc. The main task in image registration is to optimize the similarity metrics, which is a hard optimization problem. In the last two decades nature inspired algorithms, especially swarm intelligence algorithms, have been widely used for solving hard optimization problems. A number of swarm intelligence metaheuristics have been developed and they have been adjusted and tuned for image registration problem. This plenary lecture will present some successful applications of swarm intelligence algorithms to the image registration problem.
