Sparse arrays designed based on fourth-order difference co-array (DCA) can achieve significantly higher uniform degrees-of-freedom (uDOFs). However, most existing fourth-order sparse arrays do not ...

This study introduces a pseudo-4D printing strategy to construct microbubble arrays to tackle light trapping in QDs films. By direct writing of QD-doped polymers, microbubbles can be gradually ...

This paper presents a novel warping based method to stitch videos from unstructured camera arrays. Our approach adopts a two-step energy optimization for video stitching. In the first step, we perform ...
