Abstract

To address the limitation of Convolutional Neural Networks (CNNs) in capturing long-range dependencies due to their local receptive fields, this study incorporated a PVTv2 Transformer encoder for powerful global context modeling. Furthermore, to mitigate the Transformer's weaknesses in local context understanding and detail perception, the study designed three novel modules: the Residual Gated Cross-Attention Module (RGCAM) enhanced activation of relevant features and suppressed irrelevant information to strengthen both long-range and local contexts; the Multi-Kernel Parallel Convolution Attention Module (MKPCAM) fused spatial-channel attention with multi-scale convolutions to synergistically boost global dependency modeling; the Cascaded Edge-Enhanced Upsampling Module (CEEUM) hierarchically processed multi-scale edge information to improve detail perception. Experimental results on the Synapse dataset demonstrated that the proposed model achieved a DSC of 83.61% and HD95 of 15.13. The model also outperformed existing state-of-the-art methods across seven binary medical datasets. These findings validate the model's comprehensive advantages in global modeling, local semantic preservation, and detail recovery, and showcase its cross-dataset generalization capabilities.
