    This study introduces a novel feature-driven model for medical image segmentation, enhancing accuracy for complex lesions like colorectal cancer by integrating frequency domain analysis, anatomical priors, and boundary awareness.

    Area of Science:

    • Medical Imaging
    • Artificial Intelligence
    • Computational Biology

    Background:

    • Accurate medical image segmentation is vital for clinical decisions.
    • Deep learning methods struggle with complex lesion variability, limiting generalization.
    • Challenges include difficult data acquisition and diverse morphological features.

    Purpose of the Study:

    • To develop an advanced feature-driven segmentation model for improved medical image analysis.
    • To overcome limitations of traditional deep learning methods in segmenting variable and complex lesions.
    • To enhance segmentation accuracy and boundary perception in challenging medical imaging tasks.

    Main Methods:

    • A spectrum-prior-boundary triple modeling paradigm was developed.
    • Frequency domain reconstruction and modulation identified ambiguous signals.
