Histogram Tomography

open access: yesMathematics in Engineering, 2019
In many tomographic imaging problems the data consist of integrals along lines or curves. Increasingly we encounter "rich tomography" problems where the quantity imaged is higher dimensional than a scalar per voxel, including vectors tensors and ...

Three-Dimensional Film Image Classification Using an Optimal Width of Histogram

open access: yesApplied Sciences, 2023
Three-dimensional film images which are recently developed are seen as three-dimensional using the angle, amount, and viewing position of incident light rays. However, if the pixel contrast of the image is low or the patterns are cloudy, it does not look
