In order to solve the problems of visual and IR image registration, a new registration method for visual and IR image pairs is presented in this paper. As intensity discrepancy of visual and IR images, straight lines extracted by Hough transformation are used as registration primitives because these features are common to both images. The similarity transformation is considered and the parameters...
In this work, segmentation is an intermediate step in the registration and 3D reconstruction of the lung, where the diaphragmatic surface is automatically and robustly isolated. Usually, segmentation methods are interactive and use different strategies to combine the expertise of humans and computers. Segmentation of lung MR images is particularly difficult because of the large variation in image...
This work discusses the use of breathing patterns present in time sequences of MR images in the temporal registration of coronal and sagittal images. The registration is done without the use of any triggering information and any special gas to enhance the contrast. The temporal sequences of images are acquired in free breathing. As coronal and sagittal sequences of images are orthogonal to each other,...
We present in this article two complete procedures to solve some problems of the road networks. First, we must start with a process of road networks extraction based on the fuzzy clustering unsupervised approaches, and then we apply another approach for the local registration and deformation of a cartographic and a satellite road networks. For this aim, the idea is to segment first the sensed data...
