The availability of an expediting back- projection (EBP) algorithm for circular synthetic aperture radar (CSAR) imaging is investigated. EBP works by dividing the full aperture into sub-apertures, and using a unified polar grid to generate sub-images. On the basis of the correspondence between ...

Structure from motion and structure from light are usually regarded separately. To combine both methods, using the same images to retrieve three dimensional information about the environment, both methods must work side by side without interfering each other. This research work describes how laser ...

Among current BP algorithms, the fast factorized back-projection (FFBP) algorithm is one of the most essential representatives that achieve high-resolution images in an efficient manner. In this paper, the principle and applications of the FFBP algorithm are investigated through the derivation of the...
Fan beam industrial CT system usually adopts filter back-projection algorithm to reconstruct CT images. 扇束工业CT一般采用滤波反投影算法进行CT图像重构,其计算复杂度为O(N)。 2. A Fast Implementation of the Filter Back-Projection Algorithm for Fan Beam Industrial CT; 扇束工业CT一般采用滤波反投影...
The back-projection (BP) algorithm [7] is a precise time-domain imaging method; however, its high computational complexity limits its application in large-scale scenarios. Yegulalp introduced a fast back-projection (FBP) algorithm [8] with a two-level algorithmic structure to achieve lower computa...
