Accurate and early detection of precursor adenomatous polyps their removal at the stage can significantly decrease mortality rate occurrence disease since most colorectal cancer evolve from polyps. However, accurate segmentation by doctors are difficult mainly these factors: (i) quality screening with colonoscopy depends on imaging experience doctors; (ii) visual inspection is time-consuming, burdensome, tiring; (iii) prolonged inspections lead to being missed even when physician experienced. To overcome problems, computer-aided methods have been proposed. they some disadvantages or limitations. Therefore, in this work, a new architecture based residual transformer layers has designed used for polyp segmentation. In proposed segmentation, both high-level semantic features low-level spatial utilized. Also, novel hybrid loss function The focal Tversky loss, binary cross-entropy, Jaccard index reduces image-wise pixel-wise differences as well improves regional consistencies. Experimental works indicated effectiveness approach terms dice similarity (0.9048), recall (0.9041), precision (0.9057), F2 score (0.8993). Comparisons state-of-the-art shown its better performance.

Polyp segmentation within colonoscopy video frames using deep learning models has the potential to automate screening procedures. This could help improve early lesion detection rate and in vivo characterization of polyps which develop into colorectal cancer. Recent state-of-the-art polyp have combined Convolutional Neural Network (CNN) architectures Transformer (TN) architectures. Motivated by aim improving performance their robustness data variations beyond those covered during training, we propose a new CNN-TN hybrid model named FCB-SwinV2 Transformer. was created making extensive modifications recent FCN-Transformer, including replacing TN branch architecture with SwinV2 U-Net. The is evaluated on popular benchmarking datasets Kvasir-SEG, CVC-ClinicDB ETIS-LaribPolypDB. Generalizability tests are also conducted determine if can maintain accuracy when outside training distribution. consistently achieves higher mean Dice IoU scores compared other reported literature therefore represents performance. importance understanding subtleties evaluation metrics dataset partitioning demonstrated discussed.

ABSTRACT Current colorectal polyps detection methods often struggle with efficiency and boundary precision, especially when dealing of complex shapes sizes. Traditional techniques may fail to precisely define the boundaries these polyps, leading suboptimal rates. Furthermore, flat small blend into background due their low contrast against mucosal wall, making them even more challenging detect. To address challenges, we introduce SCABNet, a novel deep learning architecture for efficient polyps. SCABNet employs an encoder‐decoder structure three blocks: Feature Enhancement Block (FEB), Channel Prioritization (CPB), Spatial‐Gradient Boundary Attention (SGBAB). The FEB applies dilation spatial attention high‐level features, enhancing discriminative power improving model's ability capture patterns. CPB, alternative traditional channel blocks, assigns prioritization weights diverse feature channels. SGBAB replaces conventional mechanisms solution that focuses on map. It Jacobian‐based approach construct learned convolutions both vertical horizontal components This allows effectively understand changes in map across different locations, which is crucial detecting complex‐shaped These blocks are strategically embedded within network's skip connections, capabilities without imposing excessive computational demands. They exploit enhance features at levels: high, mid, low, thereby ensuring wide range has been trained Kvasir‐SEG CVC‐ClinicDB datasets evaluated multiple datasets, demonstrating superior results. code available on: https://github.com/KhaledELKarazle97/SCABNet .
