Abstract:A method of lung images edge detection is provided based on multi-resolution analysis for medical chest digital X-Ray images.The method combines mathematical morphology with wavelet transform technology.An image pyramid is constructed.Low-resolution edge image is propagated,searched and refined to high-resolution in the pyramid to detect and locate the lung edge.The experiment shows that calculation speed of the algorithm is very fast and the edge detected is accurate,smooth and continuous.
Keywords:Multi-resolution analysis Wavelet transform Mathematic morphology Edge detection DX image
