Paper Abstract

Filtering a sequence of images for target detection is discussed using multiresolution wavelet techniques and nonlinear size limited band filters based on partial differential operators associated with curvature of image level sets. In the latter procedure, evolution of the image under the differential operator is analogous to morphological erosion using structure sets, while backwards time evolution corresponds to dilation. The composition of these operations is subtracted from the original image to give the size limited `tophat' operator. Application of this procedure is demonstrated using synthesized targets embedded in actual infrared camera data.
