Segmentation of Meristem Cells by an Automated Optimization Algorithm

Applied Sciences, 2020
Meristem cells are irregularly shaped and appear in confocal images as dark areas surrounded by bright ones. Images are characterized by regions of very low contrast and absolute loss of edges deeper into the meristem.

Receiver Operation Characteristics of Quantum State Discrimination [PDF]

Journal of Russian Laser Research, 2017
We provide a description of the problem of the discrimination of two quantum states in terms of receiver operation characteristics analysis, a prevalent approach in classical statistics. Receiveroperation characteristics diagrams provide an expressive representation of the problem, in which quantities such as the fidelity and the trace distance also ...
