A 3D semantic scene completion method based on hierarchical grouping and aggregation

This invention proposes a 3D semantic scene completion method based on hierarchical grouping and aggregation. The model proposes a novel dual-branch structure. The explicit constraint branch starts with the overall 3D scene features, focusing on regional aspects of the scene and aggregating explicitly similar features into grouped regional features. The implicit diffusion branch starts with the visible voxel query suggestions output by the query suggestion network, focusing on the details of objects in the scene and learning the implicit fine-grained features of the objects. A hierarchical grouping module is also proposed, which divides the 3D space into multiple sub-regions and performs similarity calculation and aggregation on the voxel features within each region, thereby generating a compact regional feature representation. This grouping method can focus on the local regions of specific objects in the scene, avoiding mutual interference from features of independently distributed objects in the distance, thus extracting more detailed and accurate semantic features.

Systems and Methods for Incremental Learning for Object Detection

A method and system perform incremental learning object detection in images and / or videos without catastrophic forgetting of previously learned object classes. A two-stage neural network object detector is trained to locate and identify objects belonging to additional object classes by iteratively updating the two-stage neural network object detector until an overall detection accuracy criterion is met. The update is performed to balance minimizing the loss of the initial ability to locate and identify objects belonging to previously learned object classes and maximizing the ability to additionally locate and identify objects belonging to additional object classes. Evaluating whether the overall detection accuracy criterion is met compares the output of an initial version of the two-stage neural network object detector with current region proposals output by a current version of the two-stage neural network object detector to determine a region proposal distillation loss and a previously learned object recognition distillation loss.
