In this work, a distortion-invariant pattern recognition scheme called the composite training image method is introduced. Usually, in attempting to detect the distorted (rotated, size- changed, shifted) versions of an object, a large number of raw training (distorted) images are used. However, there is a trade-off between this number and the ratio of signal correlation intensity peak to the maximum sidelobe (RSMS). In order not to degrade this ratio, the number of training images should be reduced as much as possible. We show how to fuse several similar raw training images into a composite training image. In this paper, we illustrate the feasibility of using such composite training images.
