Abstract
A method for automatically segmenting lung regions in a chest radiographic image comprising; providing an input digital chest radiograph image; preprocessing the input digital radiographic image; extracting the chest body midline and lung centerlines from the preprocessed image. Locating one-by-one, the chest body model, the spine model and the two lung models in the image based on the extracted chest body midline and two lung centerlines; and detecting the lung contours by deforming the lung shape models to converge to the true lung boundaries as a function of the extracting and locating image processing.

3. A method for automatically segmenting lung regions in a chest radiographic image comprising:
-
providing an input digital chest radiographic image;
preprocessing the input digital radiographic image by;
(a) estimating two lung regions and a mediastinum region, and (b) normalizing the radiographic image with the estimated two lung regions and mediastinum regions;
extracting a chest body midline and two lung centerlines from the preprocessed image;
locating one-by-one, the chest body model, the spine model and the two lung models in the image based on the extracted chest body midline and two lung centerlines; and
detecting the lung regions by deforming the lung shape models to converge to the true lung boundaries using both region and edge information. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12)
