Stereophotogrammetry is finding increasing use in plastic surgery, both for breast reconstruction after oncological procedures and cosmetic augmentation/reduction. The ability to visualize and quantify morphological features of the breast facilitates pre-operative planning and post-operative outcome assessment. Breast contour is an important attribute for quantitative assessment of breast aesthetics. Based on the detected breast contour, relevant morphological measures such as breast size, shape, symmetry, volume and ptosis can be determined. In this study we present an approach for the automatic contour detection of the lower breast in three-dimensional (3D) images. Our approach employs surface curvature analysis. We first identify the points with the lowest Gaussian curvature within the one-ring neighborhood on the surface mesh, and then apply the random sample consensus (RANSAC) algorithm to non-deterministically estimate the lower breast contour from the set of low curvature points.
