在本文中，我们提出了一种方法，用于匹配的时变立体图像之间的变形对象。开发该方法主要是为了找到同一乳房的头尾（CC）（头到脚）和内外斜（MLO）（肩到对侧髋）X射线乳腺摄影之间的对应关系。这两张乳房X光照片是在乳房被压缩在X光机的暗盒和板之间时拍摄的。这导致每个方向上的压缩量不同。由不同的压缩引起的乳房的变形导致相应的点出现远离从双目立体视觉熟悉的直的"核线"。本文提出的方法是通过模拟微分变形和投影对应点的三维曲线来计算对应于CC图像中的点的MLO图像中的曲线。在真实的数据上的实验表明，该方法能很好地预测出对应位置在另一幅图像中的位置。我们还说明了该程序的能力，以估计在未压缩的乳腺病变的三维位置。(C)北京：科学出版社.
In this paper, we propose a method for matching a deformable object between time-varying stereo images. This method has been developed primarily to find correspondences between a cranio-caudal (CC) (head to toe) and a medio-lateral oblique (MLO) (shoulder to the opposite hip) X-ray mammogram of the same breast. The two mammograms are taken while the breast is compressed between the cassette and plate of the X-ray machine. This results in a different amount of compression in each direction. The deformations of the breast caused by the different compressions cause corresponding points to appear far from straight "epipolar lines" familiar from binocular stereo vision. The method developed in this paper calculates the curve in a MLO image corresponding to a point in the CC image through simulation of the differential deformation and the projection of a 3D curve corresponding to the point. Experiments on real data show that the method predicts well the corresponding position in the other image. We also illustrate the program's ability to estimate the 3D position of a lesion in the uncompressed breast. (C) 2001 Academic Press.
