An Image Registration Method for Colposcopic Images
A nonrigid body image registration method for spatiotemporal alignment of image sequences obtained from colposcopy examinations to detect precancerous lesions of the cervix is proposed in this paper. The approach is based on time series calculation for those pixels in the first image of the sequence and a division of such image into small windows. A search process is then carried out to find th...
متن کاملDPML-Risk: An Efficient Algorithm for Image Registration
Targets and objects registration and tracking in a sequence of images play an important role in various areas. One of the methods in image registration is feature-based algorithm which is accomplished in two steps. The first step includes finding features of sensed and reference images. In this step, a scale space is used to reduce the sensitivity of detected features to the scale changes. Afterw...
متن کاملApplication of an Image Registration Method to Noisy Images
The purpose of this article is twofold: First to overview the recently proposed 3D image registration algorithm presented in the Ph.D. dissertation of the first author and secondly to apply the results to the registration of images which have a certain level of noise. Our method is developed by adjusting the divergence and curl of the image displacement field by means of which we can control tr...
متن کاملAn Octree Method for Parametric Image Registration
Already for reasonable sized 3D images, image registration becomes a computationally intensive task. Here, we introduce and explore the concept of OcTree’s for registration which drastically reduces the number of processed data and thus the computational costs. We show how to map the registration problem onto an OcTree and present a suitable optimization technique. Furthermore, we demonstrate t...
متن کاملContourlet-Based Edge Extraction for Image Registration
Image registration is a crucial step in most image processing tasks for which the final result is achieved from a combination of various resources. In general, the majority of registration methods consist of the following four steps: feature extraction, feature matching, transform modeling, and finally image resampling. As the accuracy of a registration process is highly dependent to the fe...
