Latest Patents

One of Jiawei Fan's latest patents is a few-shot object detection method. This method involves sending a weight of a backbone network and a weight of a feature pyramid to a detection network. It generates candidate regions derived from a result of foreground-and-background classification and regression of output features of the visual representation backbone network by a region proposal network. The method further includes generating candidate region features of a uniform size using a pooling operator based on the candidate regions. It performs location regression, content classification, and fine-grained feature mining on these features. Additionally, it establishes fine-grained positive and negative sample pairs through feature mining and performs comparative learning between these features. The process culminates in generating a loss function based on a strategy in fine-grained feature mining, which updates detection network parameters.

Another notable patent is the physical test system of large-scale three-dimensional multi-functional landslide-prevention and control structure. This system comprises a model test tank, a bidirectional servo loading system, a multi-scale model transformation system, a sliding surface evolution visualization system, a positive pressure monitoring system, an artificial rainfall system, and a control system. The bidirectional servo loading system applies both horizontal and vertical loads, while the multi-scale model transformation system includes retractable counterforce brackets to change the width of the model test tank. The sliding surface evolution visualization system features multiple filming devices to record the entire evolution process of a landslide sliding surface.
