In remote sensing applications, the traditional procedure for registering a pair of images requires the manual selection of ground control points at significant landmarks of the images. The primary drawback of this approach is that a trained expert is needed to manually select each individual ground control point in the remotely sensed images. This is very laborious and time consuming. In this paper,...
Digital Subtraction Angiography (DSA) is a powerful technique for the visualization of blood vessels in a sequence of X-ray images. In this application, it is necessary to register multiple images of the same sequence in order to reduce patient motion artifacts. The registered images are then subtracted in order to evaluate the progress of a disease and/or a treatment procedure. In this paper, a results...
In this paper, a new feature points extraction method based on the nonsubsampled contourlet transform (NSCT) is proposed for image registration. The primary motivation of this work is to determine the effectiveness of the NSCT transform for feature points extraction for the use of image registration. The performance of the proposed NSCT-based registration algorithm is demonstrated and validated in...
