SSD is a single convolutional neural network-based object detection model that utilizes multi-scale feature maps and default box designs to perform classification and regression simultaneously. With an efficient structure, it achieves real-time object detection and is suitable for handling objects of various sizes.
| GPU | IXUCA SDK | Release | Branch |
|---|---|---|---|
| MR-V100 | 4.4.0 | 26.03 | release/26.03 |
| MR-V100 | 4.3.0 | 25.12 | release/25.12 |
Note: 请切换到与您的 SDK 版本对应的 Release 分支进行测试。请勿直接在 master 分支上运行测试，因为 master 分支可能包含与您的本地 SDK 版本不兼容的最新更改。
