• Developed an attention-based mask region-based convolutional neural network (R-CNN) for improved detection accuracy and reduced computational cost.
• Introduced an improved feature pyramidal network (iFPN) with added bottom-up paths for enhanced feature extraction.
• Proposed a novel convolutional block attention module-convolutional denoising autoencoder (CBAM-CDAE) network incorporating channel and spatial attention mechanisms.
• Implemented pose refinement for accurate 6-DoF object pose determination.

Main Results:

• The proposed attention-based mask R-CNN significantly improved detection accuracy.
• The iFPN effectively extracted deeper image features.
