Abstract: Three-dimensional (3D) point cloud information hiding algorithms are mainly concentrated in the spatial domain. Existing spatial domain steganalysis algorithms are subject to more disturbing ...

Abstract: Autonomous ground robot navigation in unstructured, mapless, and uneven terrains remains a challenging task due to variable slopes, environmental occlusions, and the need to preserve robot ...

Penn researchers have developed a universal algorithm that allows 2D materials to retain mechanical strength after conversion into 3D structures. The team’s work takes inspiration from kirigami, an ...

Engineers have created intelligent 3D printers that can quickly detect and correct errors, even in previously unseen designs, or unfamiliar materials like ketchup and mayonnaise, by learning from the ...

Example image of the 3D printer nozzle used by a machine learning algorithm to detect and correct errors in real time. Highlighted regions show aspects of the image that the system focuses on, ...
