Scientists have developed new methods for improving two of the most widespread means used in digital image processing: magnification and thresholding. The new algorithm to magnify images stands out ...

Magnification is the term for the ratio between the size of the rastered area on the sample to the size of the rastered area of the output, as depicted in Figure 1. Historically, the output size was ...

Diffractive deep neural networks (D 2 NNs) are optical systems composed of successive transmissive layers optimized through deep learning to perform computational tasks in an all-optical manner. The ...
