This paper presents a novel approach that can quickly and effectively partition images based on fully exploiting the spatially coherent property. We propose an algorithm named iterative loopy belief propagation(iLBP) to integrate the homogenous regions

Iterative methods are popular choices in image reconstruction fields due to their capability of recovering object information from incomplete acquisition data.However,the computation process involves
We present a theoretically-exact and stable computed tomography(CT) reconstruction algorithm that is capable of handling interrupted illumination and therefore of using all measured data at arbitrary
In line X-ray phase contrast micro-computed tomography(IL-XPCT),which can be implemented at third generation synchrotron radiation sources or by using a micro-focus X-ray tube,is a powerful technique
The goal of this paper is to investigate different reconstruction methods for solving the limited angle problem in reconstructing the projection data from a stationary multi-pinhole system based on a
Axial scan along circular trajectory has been the most desirable in clinical and preclinical applications.However,due to the violation of the data sufficiency condition,the reconstruction accuracy of
This paper gives an efficient approach to reconstruct moving multiple objects(multi-object).Each object has independently rigid motion which includes translation and rotation.The traditional FBP algor
A consistency condition is developed for computed tomography(CT) projection data acquired from a straight-line X-ray source trajectory.The condition states that integrals of normalized projection data
A three-dimensional(3-D) phantom for the density distribution of the plasmasphere is established .The imaging processes of the extreme ultraviolet(EUV) Imager are computer-simulated,in which the Earth
In this paper,we propose a new image denoising method that combines total variation(TV) method and wavelet shrinkage. In our method,a noisy image is decomposed into subbands of LL,LH,HL,and HH in wave
The back-projection-filtration(BPF) algorithm has been applied to image reconstruction for cone-beam configurations with general source trajectories.The BPF algorithm can reconstruct 3-D region-of-int
