Much of our research over recent years has been oriented towards pattern recognition invariant to changes of orientation, scale, 3-D rotations, illumination and other distortions. Here we propose to extend this research and some new approaches. A key concept in many parts of this program is a vector space approach to image representation and processing. The nonlinear locally adaptive correlation filter methods developed to obtain correlation peaks invariant to illumination are being extended to face recognition, and we are extending the vector space approach to change detection in images invariant under local changes of illumination. We are also working in collaboration with industry towards practical applications of some of our previous research using circular harmonic filters for security applications. In collaboration with the defense Department, we will develop the use of correlation techniques along with morphological processing for data mining purposes. Combination of correlation techniques with morphological processing should lead to some more powerful image processing techniques.

近年来，我们的大部分研究都是针对方向、尺度、三维旋转、光照和其他失真变化的模式识别。在这里，我们建议扩展这项研究和一些新的方法。在这个程序的许多部分的一个关键概念是一个向量空间的方法来表示和处理图像。非线性局部自适应相关滤波器的方法，以获得相关峰不变的照明正在扩展到人脸识别，我们正在扩展的向量空间方法，在图像中的变化检测不变的局部变化的照明。我们还与工业界合作，将我们以前的一些研究成果应用于安全应用中。在与国防部的合作中，我们将开发相关技术的使用，沿着形态学处理，用于数据挖掘目的。相关技术与形态学处理的结合将产生一些更强大的图像处理技术。
