    This study introduces multilevel band pass filtering for chest radiograph analysis. This technique separates textural and skeletal components, improving image evaluation and enabling targeted enhancement of specific structures.

    Area of Science:

    • Digital image processing
    • Radiological imaging analysis
    • Medical image filtering

    Context:

    • Conventional chest radiographs lack detailed structural separation.
    • Evaluating subtle changes in radiographs can be challenging.
    • Existing methods may not effectively isolate specific image components.

    Purpose:

    • To develop a digital image processing technique for chest radiographs.
    • To separate textural and skeletal components using multilevel band pass filtering.
    • To facilitate the evaluation of radiological images by analyzing components at different levels.

    Summary:

    • Chest radiographs were digitized and processed using multilevel band pass filtering.
    • This method isolates structural components based on local spatial frequencies, separating textural from skeletal elements.
