Due to this binary nature, the BT problem usually requires projections from only a few view angles to solve, in stark contrast to the hundreds or thousands of view angles …
WebIn binary tomography, we consider a discrete version of the above tomography problem. Our ctitious X-rays probe information about a m nbinary matrix A, telling us the row and column sums. The original problem in binary tomography is then to construct an m nbinary matrix with speci c row and column sums. Ryser, and independently Gale,
WebJul 8, 2024 · The topic of this paper includes graph cuts based tomography reconstruction methods in binary and multi-gray level cases. A energy-minimization based reconstruction method for binary tomography is introduced. This approach combines the graph cuts and a gradient based method, and applies a shape orientation as an a priori information. fighting rooster stencilWebJun 19, 2006 · Abstract.
