3DPPE: 3D Point Positional Encoding for Transformer-based Multi-Camera 3D Object Detection

1 code implementation ICCV 2023 Changyong Shu, Jiajun Deng, Fisher Yu, Yifan Liu

Although 3D measurements are not available at the inference time of monocular 3D object detection, 3DPPE uses predicted depth to approximate the real point positions.

Channel-wise Knowledge Distillation for Dense Prediction

3 code implementations ICCV 2021 Changyong Shu, Yifan Liu, Jianfei Gao, Zheng Yan, Chunhua Shen

Observing that in semantic segmentation, some layers' feature activations of each channel tend to encode saliency of scene categories (analogue to class activation mapping), we propose to align features channel-wise between the student and teacher networks.
