The core of Multi-view Stereo(MVS) is the matching process among reference and source pixels. Cost aggregation plays a significant role in this process, while previous methods focus on handling it via CNNs. This may inherit natural limitation CNNs that fail to discriminate repetitive or incorrect matches due limited local receptive fields. To handle issue, we aim involve Transformer into cost aggregation. However, another problem occur quadratically growing computational complexity caused by...

Tunnels for subways and railways are a vital part of urban transportation systems, where shield tunneling using assembled segmental linings is the predominant construction approach. With increasing operation time varying geological conditions, tunnels usually develop defects that compromise both structural integrity operational safety. One common issue separation segment joints may cause water/mud penetration corrosion. Existing inspection strategies can only detect openings after their...
