Abstract : Summarizes work performed by McDonnell Douglas Aerospace on a contract under the ARPA University-Industry ATR Initiative. The focus is on a preliminary investigation into the use of wavelets to extract local feature points to be used for matching 2-D and 3-D structure in multiple images. The approach is to detect dominant local discontinuities (i.e., point features, corners, curvature discontinuities) as a function of wavelet coefficients.
