Inspecting the condition of the key components of freight trains is an important task in the rail
industry. Bolts on the wheel bearings are key components of a bogie, and bolt defects, such …

In recent years, microbial metabolomics, a new field that has attracted wide attention,
provides a map of metabolic pathways and clarifies the interaction mechanism between …

Recent vision-brain physiological experiments [65] have demonstrated that contours, and in
particular, contour junctions present in the 2D images are very informative for revealing the …

Fault inspection plays an important role in ensuring the safe operation of freight trains. With
the development of computer vision technology, the vision-based fault inspection has …

The trouble of freight car detection system (TFDS) is a popular application in Chinese
railway today. In this paper, the discrete-point sampling model is further developed to locate …

Long runs of railway trains inevitably lend to fault conditions. Automatic detection of defects
in train components is very important for train safety and maintenance. For a long time, our …
