STEMPix: A Phase-Transition-Material-Based Pixel Sensor for Resolving Edge-Movement Direction

On September 7, 2026, the research paper STEMPix was published on arXiv cs.CV. It introduced a new type of pixel sensor based on Phase-Transition-Material. This sensor aims to address the limitations of traditional imaging techniques in capturing the direction of edge movements, using the physical properties of Phase-Transition-Material to more accurately determine the direction of object edges.
