MD3D: Mixture-Density-Based 3D Object Detection in Point Clouds

Jaeseok Choi;Yeji Song;Yerim Kim;Jaeyoung Yoo;Nojun Kwak

IEEE Access
Year: 2022 | Volume: 10 | Journal Article |
Cited by: Papers (4)
The design factors of anchor boxes, such as shape, placement, and target assignment policy, greatly influence the performance and latency of the 3D object detectors. Unlike image-based 2D anchors, 3D anchors must be placed in a 3D space and determined differently for each class of different sizes. This imposes a significant burden on the design complexity. To tackle this issue, various studies hav...Show More

Self-example-based super-resolution (SR) methods utilize internal dictionaries to reconstruct a high-resolution (HR) image from a single low-resolution (LR) input image. In general, a square-sized patch is used to find the LR-HR correspondences in the dictionaries.
