In this paper we introduce the notion of a focused filter and discuss its application to the problem of target detection. A focused filter is a filter designed to give a maximum response to one pose of the target. This pose is called the focus of the filter. As the pose of the target deviates from the focus, the filter's responses should exhibit a graceful (and controlled) degradation. When presented with a test image, the responses of all focused filters are collected in a vector. This new vector will have a peak with the same shape as that used in designing one focused filter. Preliminary simulation experiments shows the robustness of this method.
