所提出的Trace变换是Radon变换的一种推广，它包括用直线跟踪图像，沿着直线计算图像函数的某些函数。可以使用的不同函数对于图像的不同变换可能是不变的。本文介绍了该方法在三种不同应用中必须具备的性质：构造图像旋转、平移和缩放的不变特征，构造图像旋转、平移和缩放参数的敏感特征，以及构造可能与我们希望监测的某种现象密切相关的特征。
The Trace transform proposed, a generalization of the Radon transform, consists of tracing an image with straight lines along which certain functionals of the image function are calculated. Different functionals that can be used may be invariant to different transformations of the image. The paper presents the properties the functionals must have in order to be useful in three different applications of the method: construction of invariant features to rotation, translation and scaling of the image, construction of sensitive features to the parameters of rotation, translation and scaling of the image, and construction of features that may correlate well with a certain phenomenon we wish to monitor.
