Real time and high-precision optical flow estimation is crucial for analyzing dynamic scenes in computer vision. Although traditional methods are fundamental, they often encounter issues with computation and accuracy, especially when executed on edge devices. The emergence of deep learning has driven the development of this field, providing higher accuracy, but at the cost of sacrificing computati...

backgroundThe Jörg Debus team from the Technical University of Dortmund in Germany is dedicated to researching optical quantum information processing and quantum sensing in materials with potential applications. The team mainly studies the fine structure of materials under light fields, such as quantum dots, quantum effects of two-dimensional materials, semiconductor defects in diamonds, and ...

Terahertz waves have significant application value in communication and imaging. The nonlinear interaction between strong field ultrafast laser and matter is one of the important ways to generate terahertz waves. The experimental and theoretical research related to terahertz generation media such as plasma, gas, and crystal is relatively sufficient. However, liquid water is a strong absorbing medi...
