EEP-3DQA: Efficient and Effective Projection-based 3D Model Quality Assessment

The proposed EEP-3DQA method is used for no-reference 3D model quality assessment. It first randomly samples several projections from the 6 perpendicular viewpoints and then employs the grid mini-patch sampling to convert the projections into spatial grids while maintaining the local patterns. Later, the lightweight Swin-Transformer tiny is used as the feature extraction backbone to extract quality-aware features from the sampled projections.
