The study aims to improve the accuracy and efficiency of point cloud classification and segmentation using a new network architecture.
Developed a lightweight classification and segmentation network called AFE-PointNet.
Implemented an element-wise weighting set abstraction module based on the Hadamard product for feature enhancement.
Utilized a cascaded structure with an inverted residual multi-layer perceptron for deep feature mining.
AFE-PointNet achieved an overall accuracy of 93.6% on the ModelNet40 dataset.
Achieved an overall accuracy of 84.5% on the ScanObjectNN dataset.
Attained a class mean intersection over union of 83.6% on the ShapeNetPart dataset, outperforming the PointNet++ model.
