Project overview

The work introduces CSA-AInceptNet, a unified architecture for two tightly coupled manipulation tasks: identifying an object and estimating where it should be grasped. Channel sharpening attention and adaptive inception processing are used to strengthen shared event-based features while transfer learning improves generalisation across datasets.

Core contributions

  • A single multi-task model for event-based object classification and grasping-position detection.
  • Channel sharpening attention to emphasize discriminative event features.
  • Adaptive inception processing to capture information at multiple spatial scales.
  • Cross-dataset transfer learning from E-Grasp to Neuro-Grasp for robotic manipulation.

Reported evidence

99.47%object-recognition accuracy on E-Grasp
0.9370mean IoU for grasp detection on E-Grasp
98.58%object-recognition accuracy on Neuro-Grasp

On Neuro-Grasp, the transferred model reports a mean IoU of 0.4897 in addition to 98.58% classification accuracy. Comparative and ablation experiments evaluate the proposed architecture against ConvNeXt, DarkNet, DenseNet, VGG16, and other alternatives.

Datasets and evaluation

  • E-Grasp: primary event-camera benchmark for object recognition and grasp-position detection.
  • Neuro-Grasp: target dataset used to evaluate transfer learning and cross-dataset generalisation.
  • Joint evaluation using classification accuracy and mean Intersection over Union for grasp localization.

Relevance to human-in-the-loop robotics

Joint recognition and grasp detection can reduce the number of separate perception pipelines required by a robot. This is especially useful in dynamic human–robot workspaces, where the robot must quickly understand both what an object is and how to interact with it.
