Extensive experimental results on two popular 3D shape retrieval datasets have validated the effectiveness of the soft margin triplet-center loss, and our proposed 3D shape retrieval method has ...

We report a method of the construction of a sub-diffraction limit 3D focal spot array by a 4Pi focusing system consisting of two high-numerical-aperture (NA) objectives. The approach can be achieved ...

Solution self-assembly of coil-crystalline diblock copolypeptoids has attracted increasing attention due to its capability to form hierarchical nanostructures with tailorable morphologies and ...

IJPRAI welcomes articles in Pattern Recognition, Machine and Deep Learning, Image and Signal Processing, Computer Vision, Biometrics, Artificial Intelligence, etc.

In this work diffraction of light and x-rays (XRD) on opal-like structures (OLS) is considered. New methodological approaches to collection, processing and interpretation of experimental data are ...

This enables precise, diffraction-limited control of light in three dimensions, paving the way for highly customized and sophisticated optical functions for 3D optical information processing.
