| 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. |
