dc.description.abstractIn biological image analysis, instance segmentation is crucial but challenging due to newlineoverlapping objects, blurry boundaries, complex backgrounds, and variations in object newlineappearances. This study introduces an enhanced DenseNet architecture I and#8722; DNet that newlineutilizes a residual attention feature integration method to effectively combine instance newlineand semantic information. I and#8722;DNet resolves segmentation challenges by augmenting newlinethe model s ability to assimilate contextual information through the integration of semantic newlinecontext and instance predictions. Reliability is enhanced by a robust sub-branch newlinethat aligns object recognition precision with predictive confidence. The research explores newlineportable deep learning methodologies for lung image segmentation, specifically newlinedesigned for X-ray imaging devices and independent of cloud computing. A novel newlinescaled attention mechanism s and#8722; AM is proposed, specifically designed for advanced newlineX-ray apparatus. A compilation of 360-degree lung X-ray images is utilized to train the newlines-AM model alongside other economical deep learning techniques. The rapid segmentation newlineapproaches are evaluated and contrasted using several accuracy metrics. A novel newlinepanoptic-segmentation model is introduced to markedly enhance segmentation accuracy newlineby bidirectional communication within a transformer network, integrating instance newlineand semantic information. The bidirectional link established between the memory path newlineand the CNN pixel path ensures the seamless operation of the dual-path transformer newlineblock. The system integrates multiscale features from various decoding algorithms using newlinestacked decoding blocks. The transformer architecture integrates essential mechanisms newlinesuch as pixel-to-pixel self-attention, memory-to-memory self-attention, pixelto- newlinememory feedback attention, and memory-to-pixel attention. The proposed models newlinedemonstrate significant improvements in lung segmentation tasks, enhancing both performance newlineand reliability. These advancements streamline the medical workflow and newlineimprove patient care outcomes by
