Abstract

The projection-slice theorem, often used in tomographic applications for medical imaging, is utilized in conjunction with the SDF concept to implement a distortion-invariant filter. The marriage of these two well-known fields results in an effective tool for invariant pattern recognition. 1D filtering and phase-only techniques are used to implement the projection-slice synthetic discriminant function filter, which is then compared with bench-mark filters, such as the SDF filter and the matched filter in both complex and phase- only forms for a particular set of images.
