On the Realization and Analysis of Circular Harmonic Transforms for Feature Detection
Hugh L Kennedy
Circular-harmonic spectra are a compact representation of local image features in two dimensions. It is well known that the computational complexity of such transforms is greatly r…
Multidimensional Digital Smoothing Filters for Target Detection
Hugh L. Kennedy
Recursive, causal and non-causal, multidimensional digital filters, with infinite impulse responses and maximally flat magnitude and delay responses in the low-frequency region, ar…
Parallel software implementation of recursive multidimensional digital filters for point-target detection in cluttered infrared scenes
Hugh L. Kennedy
A technique for the enhancement of point targets in clutter is described. The local 3-D spectrum at each pixel is estimated recursively. An optical flow-field for the textured back…
Multidimensional Digital Filters for Point-Target Detection in Cluttered Infrared Scenes
Hugh L. Kennedy
A 3-D spatiotemporal prediction-error filter (PEF), is used to enhance foreground/background contrast in (real and simulated) sensor image sequences. Relative velocity is utilized…
