Core Architectural Components
The Residual-SwinCA-Net integrates several innovative architectural components to achieve superior segmentation performance. These include specialized residual blocks for local features, customized Swin Transformers for global context, and advanced attention mechanisms for refined feature weighting.
Residual Learning for Local Correlated/Texture Variation
A systematic CNN residual approach has been applied to the encoder side of the proposed Residual-SwinCA-Net framework for progressively learning discriminative breast cancer features from image-based datasets. Giving the images directly to the transformer blocks will miss the local information; therefore, we have passed the BUSI through the residual blocks for learning local correlated and texture patterns. This residual block employs a 1×1 convolution for channel-wise transformation, followed by a 3×3 linear projection layer to map the learned representations into richer and more distinct output dimensionalities. For ensuring the adaptive nature preservation of the fine-grained local details, such as subtle texture variations and tumor boundaries, by incorporating a 3×3 kernel size, which is critical for reliable breast cancer analysis. The residual block learn complex BUSI lesion patterns and keeps the gradient flow intact through its skip connection.
Customized SwinT for Global Structural Feature Extraction
The transformer encoder consists of a MSA module and a Multi-Layer Perceptron (MLP), both preceded by LN and followed by residual connections, which facilitate stable gradient flow at each stacking layer. The transformer input layers are carefully customized for the imaging domain of the breast cancer dataset in the proposed 'Residual-SwinCA-Net' segmentation framework. Specifically, preceding residual CNN blocks are incorporated to extract locally correlated features. These features comprise a significant BUSI lesion pattern, like dense tissue regions, tumor boundaries, and subtle textural variations. A windowing-W-MSA mechanism incorporated by Swin Transformer overcomes computational limitations by restricting attention to localized regions. This localized attention improves both efficiency and sensitivity to small-scale abnormalities.
Multi-Scale Channel Attention and Squeezing (MSCAS)
The MSCAS block is introduced for capturing multi-scale channels from diverse receptive fields into a single discriminative descriptor. A multi-scale squeeze extracts both global and boundary-aware cues, which involves a lightweight excitation stage using 1×1 convolution, normalization, and nonlinear gating that leverages to emphasize channels tied to subtle tumor boundaries and heterogeneous tissue texture. SoftMax-normalized attention weights subsequently reweight the feature map, amplifying clinically meaningful channels while suppressing redundant or background-driven activations. Through this targeted recalibration, MSCAS improves hierarchical feature flow and substantially elevates the encoder's ability to represent malignant structures under dense-tissue and noise-prone imaging conditions.
Pixel Attention for Fine-Grained Focus
This block will perform a pixel attention mechanism, which enhances the discriminative ability of the segmentation network by allowing it to focus on the most informative spatial locations within each feature map. Pixel attention helps in the discrimination of the lesion region by giving weight to the individual pixel, unlike channel attention, where emphasis was placed upon channel-level features. This kind of pixel attention is important due to the variant natures of the pixels with intra and inter class, irregular shapes, and low contrast boundaries. Pixel attention suppresses background level information and highlights tumor edges, micro-lesion clusters, and texture irregularities, improving lesion discrimination and noise reduction.
