Meaningful performance assessment of image analysis algorithms depends on objective and transparent performance metrics. Despite major shortcomings in the current state of the art, so far only limited attention has been paid to practical pitfalls associated with the use of particular metrics for an image analysis task. Therefore, a number of international initiatives have collaborated to...
Ptychography is a high-resolution imaging technique known for being capable of reaching sub-10 nm resolution. A coherent beam is required to reach this resolution. Currently, the coherent fraction of the beam for third-generation synchrotron sources is only 10%. Thus, ptychography needs to isolate the coherent flux. Consequently, more than 90% of the incoming X-rays are wasted. This reduces...
