我们解决的问题，找到一个初始估计的图像上的地标的位置，当地标是难以区分的图像上，当位置是依赖于一起从外力，如增长。我们的方法解决了这个问题，使用自适应坐标空间的位置注册。在这个空间中，可变性大大降低。观察训练集以自动构建地标的均值和变异性模型。该模型用于预测新图像的初始估计。将该方法应用于头颅X线片的判读难题，取得了较好的效果。
We address the problem of finding an initial estimation of the location of landmarks on an image, when the landmarks are difficult to distinguish on the image and when the locations are dependent together from external forces such as growth. Our method solves the problem using an adaptive coordinate space where locations are registered. In this space, variability is greatly reduced. A training set is observed to build automatically a mean and a variability model of the landmarks. This model is used to predict the initial estimation on a new image. This method is applied to the difficult problem of the interpretation of cephalograms, with good results.
