Paper Abstract

Distortion-invariant correlation filters are used to detect and recognize distorted objects in image scenes. We describe a new way to design distortion-invariant correlation filters that ensures good generalization (same performance on training and test sets). The traditional way of designing correlation filters uses different types of frequency domain preprocessing and linear combination of training images. We show that these different approaches can be implemented in a framework using linear combination of eigen-images of preprocessed training data. Using eigen-domain data is shown to generalize well regardless of preprocessing used. We show results on SAR data using eigen-MINACE filters.
