Ridge detection in digital imagery, unlike edge detection, is an area that has received relatively little attention. Ridges are long, narrow structures that are perceptibly brighter than the background. Examples of ridges include roads in aerial images and vessels in medical images. The ability to rapidly and accurately label ridge pixels in a digital image(More)
A CT reconstruction algorithm to obtain selective tomography from multiple CT slices for localized 3D reconstruction is developed. The proposed method uses Radon transform to obtain projections for a region of interest. Image reconstruction is performed using filtered back projection technique. The property that distinguishes the developed algorithm from(More)
