Binary Image Reconstruction Using Local Binary Pattern …

WebProblem description. The least-squares formulation of a binary tomography problem is. where A is a tomography matrix of size m times n, b is the tomographic data of size m times 1, and x is a binary image that has grey levels 0 and 1. This problem is NP-hard to solve. We propose to solve the following convex program instead: WebA recently introduced Difference-of-Convex-Functions programming approach to limited-angle binary tomographic reconstruction is complemented with Expectation-Maximization iteration, and it is shown that parameter estimation can be combined with the reconstruction process. We study two scenarios of limited-angle binary tomography with data distorted … WebAlso, when the "both-positive rule" for combining binary tests was used, adding EarlyCDT-Lung to risk models improved diagnostic performance with high specificity (>92%) and positive predictive value (>70%).
