What are the Challenges of Region Growing in Cancer Imaging?
Despite its advantages, region growing also faces some challenges:
Selection of Seed Points: Accurate initial seed point selection is critical for successful segmentation. Incorrect seed points can lead to poor results. Homogeneity Criteria: Defining appropriate similarity criteria can be complex, especially in heterogeneous tumors. Noise Sensitivity: Medical images often contain noise, which can affect the accuracy of region growing. Boundary Leakage: The algorithm may sometimes include adjacent non-tumor tissue, especially in areas with gradual intensity changes.
