Paper Abstract
An improvement to the wavelet-modified Optimal Trade-off Maximum Average Correlation Height (OT-MACH) filter
with the use of the Rayleigh distribution filter is proposed. The Rayleigh distribution filter is applied to the OT-MACH
filter to provide a sharper low frequency cut-off than the Laplacian of Gaussian based wavelet filter that has been
previously reported to enhance OT-MACH filter performance. Filters are trained using a 3D CAD model and tested on
the corresponding real target object in high clutter environments acquired from a Forward Looking Infra Red (FLIR)
sensor. Comparative evaluation of the performance of the original, wavelet and Rayleigh modified OT-MACH filter is
reported for the recognition of the target objects present within the thermal infra-red image data set.
